How to restrict the guest account

Step 1:
Log into a local administrative account.
Choose Manage from the My Computer Context Menu.
From the Computer Management window browse to
System Tools > Users and Groups > Users
Double click on Guest to access the Guest Properties window
Click the Member Of tab
Click the Add button
From the Select Groups window click the Advanced... button
Click on the Find Now button
Select Administrators from the list
Keep clicking on all the OK buttons till it exits the Guest Properties window

This step just gave the guest account administrative privileges to run tools such as regedit, GPedit.msc, Services.msc, MMC, DOC, etc.

Close all the open windows and log off from the administrative account.

Step 2:
Log into the local Guest account.

Apply whatever restrictions you wanted to add to the guest user using regedit, MMC, or other tools.

Log off from the Guest Account.

Step 3:
Log back into the Administrative account.

Go back into Local Users and Groups>Users>Guest

Open the Guest Properties and click the Member Of tab. Select Administrators and click the Remove button.
Click OK.

Thats it. You now have a guest account with whatever restrictions you wanted to apply to it.

Prohibit a user from changing LAN settings using the registry

To provide restrictions even for administrator accounts merge the following in the registry:

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Network Connections]
"NC_EnableAdminProhibits"=dword:00000001

To prohibit access to properties of a LAN connection:

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Network Connections]
"NC_LanProperties"=dword:00000000

To disable the Ability to enable/disable a LAN connection:

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Network Connections]
"NC_LanConnect"=dword:00000000

To prohibit TCP/IP advanced configuration:

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Network Connections]
"NC_AllowAdvancedTCPIPConfig"=dword:00000000

To Prohibit access to the advanced settings item on the advanced menu:

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Network Connections]
"NC_AdvancedSettings"=dword:00000000

To Prohibit access to the new connection wizard:

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Network Connections]
"NC_NewConnectionWizard"=dword:00000000

Prohibit a user from changing LAN settings using Group Policies

One way is to give a limited account to the user. But what about accounts that need other administrative privileges? Well here how you can restrict network settings for the administrative user account:

Run GPEdit.msc

Go to User Configuration> Administrative Templates > Network > Network Connections.

Here you’ll find many network restrictions.

The ones I find useful are:
Prohibit access to properties of a LAN connection
Ability to enable/disable a LAN connection
Prohibit TCP/IP advanced configuration
Prohibit access to the advanced settings item on the advanced menu
Prohibit access to the new connection wizard

None of the above seemed to be working for an administrative account. Later on I learned that for it all to work in an administrative account I had to enable this:

Enable Windows 2000 Network Connections settings for Administrators.

How to edit the windows registry: Video tutorial for beginners

Well here’s a simple video tutorial to edit the registry. It lacks audio though.

Hope it helps somebody:)

Prevent changing file associations using the Folder Options

Disable access to a drive

To prevent users from using My Computer, Explorer, Run, Map Network Drive to access the content of selected drives:

In the Windows Registry Editor (regedit) navigate to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Create a new DWORD Value named: NoViewOnDrive

The value for NoViewOnDrive needs to be calculated as follows:

A drive that needs to be hidden is represented by a binary 1.

ZYXWVUTSRQPONMLKJIHGFEDCBA
00000000000000000000100000

For example to hide drive F the value for NoDrives = 20 in hexadicimal

Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] "NoViewOnDrive"=dword:00000020

To hide all drives except C, D and E the binary value is 11111111111111111111100011

So the value for NoDrives will be: 3FFFFE3

If a user tries to access the drive he will get a restriction warning stating "This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator."

Disable personalizing the target location for My Documents, My Music, My Pictures and Favourites

Detecting Arrow keys on a windows form application using VB.NET

Handling arrow keys on a VB windows form is a pain until you find a solution that works according to your needs:) Well I posted this coz I got excited having solved a problem I had with detecting the arrow keys in VB.NET. I've been struggling to detect the arrow keys on a windows application form that I was designing in VB 2008.

The form contained a TabControl and needed to detect the keys only on TabPage1. Since there were many other controls on the form I had to use an overriding function.

i.e:

Protected Overrides Function ProcessCmdKey(ByRef msg As Message, _ ByVal keyData As Keys) As Boolean

 ' detect which key is pressed and perform some action

End Function

The problem is that TabPage2 contained a textbox and would allow me to enter only a single character. To continue typing into the textbox I needed to click in the textbox and type the next character. To overcome this problem I needed to check which TabPage had the focus. But the problem was where to check the focus.

Download my code to find out how I solved my problem: http://www.mediafire.com/?wnw3zduymtj Hopefully someone finds this post useful.

Configure Hidden options through the registry

To disable changing the hidden files and folder settings in Folder Options:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL] "CheckedValue"=dword:00000000

To disable showing hidden files and folders:

Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced] "Hidden"=dword:00000000

To disable showing superhidden files and folders:

Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced] "ShowSuperHidden"=dword:00000000

To enable changing the hidden files and folder settings in Folder Options:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL] "CheckedValue"=dword:00000001

To enable showing hidden files and folders:

Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced] "Hidden"=dword:00000001 To enable showing superhidden files and folders: Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced] "ShowSuperHidden"=dword:00000001

Edit the registry using Powershell

If you use the Get-PSDrive cmdlet you'll notice that HKCU and HKLM appear as drives. This allows us to use item cmdlets to manage items in the HKLM: and HKCU: drives.

To change your location to the HKCU: drive use either Set-Location HKCU: or cd HKCU:

To navigate through the registry drive: you can use cd the same way you would use it to navigate through directories in the command prompt. You can also use Set-Location

Example to navigate to HKCU/Control Panel/Desktop
PS HKCU:\> Set-Location "HKCU:/control panel/desktop"

or

PS HKCU:\> cd "HKCU:/control panel/desktop"

To view subkeys: Use either dir or Get-ChildItem

To create a new registry key:
To create a new registry key within a subkey we can use the New-Item cmdlet
For example, to create a key named PUNKISNAIL under hkcu/control panel/desktop
PS HKCU:\control panel\desktop> New-Item PUNKISNAIL

To delete a registry key:
Here we can use the remove-item cmdlet.
For example to delete the key PUNKISNAIL which we created under hkcu/control panel/desktop use:
PS HKCU:\control panel\desktop> remove-item PUNKISNAIL

If you're in a different drive you can use the following to delete the key:
PS C:\>remove-item -path "hkcu:/control panel/desktop/punkisnail"

To get the registry entries in a key:
Here we can use the Get-ItemProperty cmdlet.

To get the properties for menushowdelay found in HKCU/Control Panel/Desktop use: Get-ItemProperty -path "hkcu:/control panel/desktop" -name menushowdelay

To create a registry entry use:
new-itemproperty -path somepath -name someEntryName -value AnyValue -propertyType SomeType Example: new-itemproperty -path "HKCU:/control panel/desktop/punkisnail" -name MyNameIs -value "Shane Lobo" -propertyType string

possible property types are: String, ExpandString, Binary, DWord, MultiString, QWord, Unknown

To clear the value of a registry entry use:
Clear-ItemProperty Clear-ItemProperty -path SomePath -name SomeEntryName

To delete a registry entry use:
remove-ItemProperty remove-ItemProperty -path SomePath -name SomeEntryName

Killing processes using the command prompt

To kill a process in the command prompt we need to know either its Image Name or Process ID. One way to find this is in the Windows Task Manager. The other way is to use the Tasklist command in the command prompt.

Command to kill a process in Windows XP Pro:

 taskkill [/pid processID | /im ImageName]} [/f] [/t]

/pid processID Specifies the process ID of the process to be terminated.

/im ImageName Specifies the image name of the process to be terminated.

Use the wildcard character (*) to specify all image names.

/f Specifies that processes be forcefully terminated.

/t Terminates the specified process and any child processes started by it.

Example: taskkill /im notepad.exe

Command to kill a process in Windows XP Home Edition: Windows XP Home Edition users can use the tskill command as follows: tskill {processID | processName}

Example: tskill notepad

Edit the registry using the command prompt

To know the contents of a particular registry key or a particular value:

REG QUERY KeyName [/v ValueName | /ve] [/s]

/v Specifies the registry value name that is to be queried.

/ve Runs a query for value names that are empty.

/s Specifies to query all subkeys and value names recursively. Example to query the value of menushowdelay at HKCU/control panel/desktop

reg query "hkcu/control panel/desktop" /v menushowdelay

To add new registry keys:

REG ADD KeyName [/v ValueName | /ve][/t Type][/d Data] [/f]

/t Specifies the type for the registry entry which must be one of the following: REG_SZ REG_MULTI_SZ REG_DWORD_BIG_ENDIAN REG_DWORD REG_BINARY REG_DWORD_LITTLE_ENDIAN REG_LINK REG_FULL_RESOURCE_DESCRIPTOR REG_EXPAND_SZ

/d Specifies the data for the new registry entry.

/f Adds the registry entry without prompting for confirmation.

Example to change the value of menushowdelay to 0:
reg add "hkcu/control panel/desktop" /v menushowdelay /t REG_SZ /d 0

To delete registry keys:

REG DELETE KeyName [/v ValueName | /ve | /va] [/f]

/va Deletes all entries under the specified subkey. Subkeys under the specified subkey are not deleted.

to export and import registry keys:

To export: REG EXPORT KeyName FileName

To import: REG IMPORT FileName

Manage services using windows powershell

To get a list of objects representing the services and their running status:
type: get-service
To get the status of a particular service, type: get-service -name servicename
where, servicename is the short name for the service.
To get the status for a service using its display name, type:
get-service -displayName "displayname"
example: get-service -name wuauserv
get-service -displayName "Automatic Updates"
both the examples will give the same result.

To start, stop, pause and resume services:
To start a service using short names , type: start-service -name servicename
To start a service using display names, type: start-service -displayName "displayname"

To stop a service using short names , type: stop-service -name servicename
To stop a service using display names, type: stop-service -displayName "displayname"

To pause a service using short names , type: suspend-service -name servicename
To pause a service using display names, type: suspend-service -displayName "displayname"

To resume a service using short names , type:resume-service -name servicename
To resume a service using display names, type: resume-service -displayName "displayname"

To restart a service using short names , type: restart-service -name servicename
To restart a service using display names, type: restart-service -displayName "displayname"

To set how a service starts up:
set-service -name servicename -startupType {<automatic>|<manual>|<disabled>}
or
set-service -displayName displayname -startupType {<automatic>|<manual>|<disabled>}
Example: set-service -name wuauserv -startupType manual

Change attributes of a file using the command prompt

The attrib command is used to Display, set, or remove attributes assigned to files or directories. using attrib without parameters displays attributes of all files in the current directory.

Syntax
attrib [{+|-}r] [{+|-}a] [{+|-}s] [{+|-}h] [{+|-}i] [drive:][path][fileName] [/s [/d] [/l]]
+ is for setting the attribute
- is for clearing an attribute
r is for the Read-only file attribute.
a is for the Archive file attribute.
s is for the System file attribute.
h is for the Hidden file attribute.
i is for the Not Content Indexed file attribute.

/s Applies attrib and any command-line options to matching files in the current directory and all of its subdirectories.

/d Applies attrib and any command-line options to directories.

/l Applies attrib and any command-line options to the Symbolic Link, rather than the target of the Symbolic Link.

If a file has the System (s) or Hidden (h) attribute set, you must clear the attribute before you can change any other attributes for that file.

Examples:
To assign the Read-only attribute to the file named Report.txt, type:
attrib +r report.txt
To remove the Read-only attribute from files in the Public directory and its subdirectories on a disk in drive B, type:
attrib -r b:\public\*.* /s

Managing Windows Services using the command prompt

To configure how a service starts: sc config servicename start= {auto|demand|disabled}

use auto for services that need to automatically start each time the computer is restarted.
use demand for services that need to be started manually.
use disabled for services that need to be disabled/prevented from starting..

To create a text list of running services use the command:
sc query > serviceslist.txt

To create a list of all services, use:
sc query type= service state= all > allserviceslist.txt

To start, stop, pause and resume services:

To start a service, type:
net start servicename

To stop a service, type:
net stop servicename

To pause a service, type:
net pause servicename

To resume a service, type:
net continue servicename

servicename Specifies the short name of the service.

 

To get the short name of the service from the descriptive name (Example for Remote Registry): sc getkeyname "Remote registry"

Download a list of short names for services: http://www.mediafire.com/?zfmyzd5yjzy

Using Netsh to configure IP settings

To get the IP automatically using DHCP use this command:
netsh int ip set address "local area connection" dhcp

To get the DNS server address automatically:
netsh int ip set dns "local area connection" dhcp

local area connection can have any name. Just look in your control panel>Network Connections for the correct name.

To set a static IP address use this command:
netsh interface ip set address "Local Area Connection" static ipaddr subnetmask gateway metric

NOTE: Replace ipaddr with the static IP address, subnetmask with the subnet mask, gateway with the default gateway and, if necessary, metric with the appropriate metric.

The following example changes the interface "Local Area Connection" to a static address of 192.168.0.10 with a subnet mask of 255.255.255.0, and the interface has a default gateway of 192.168.0.1 with a metric of 1:

netsh interface ip set address "Local Area Connection" static 192.168.0.10 255.255.255.0 192.168.0.1 1

 

To change the DNS server address use:
netsh int ip set dns "local area connection" static 192.168.0.254 primary

To add more DNS server addresses entries use:
netsh int ip add dns "local area connection" 192.168.1.254

How to hide applets in the control panel

The control panel applets are stored in the X:\WINDOWS\system32 folder.

X: represents the drive where you have installed windows.

Open regedit. Navigate to HKEY_CURRENT_USER\Control Panel\don't load

Insert a new String value and rename it with the applets name that you want to hide. Give it the value: No

Prevent access to registry editing tools

Method 1: One way to do this in Windows XP professional is through gpedit.msc

Start>Run... type: gpedit.msc

In the 'Group Policy' window expand 'User Configuration' expand 'Admininstravive Templates' and select 'System'

Double-click 'Prevent access to registry editing tools' in the pane towards the right.

Choose 'Enabled' and apply.

 

Method 2: The second way is to use the registry itself. To disable it for the current user: [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System] "DisableRegistryTools"=dword:00000001

To disable it for all users: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System] "DisableRegistryTools"=dword:00000001

If one tries to run regedit after applying this tweak a message box will appear stating "Registry editing has been disabled by your administrator"

Hiding Drives in the Windows Explorer

This will hide a particular drive in My Computer, Explorer, Send To, ... In the Windows Registry Editor (regedit) navigate to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Create a new DWORD Value named: NoDrives

The value for NoDrives needs to be calculated as follows:
A drive that needs to be hidden is represented by a binary 1.

ZYXWVUTSRQPONMLKJIHGFEDCBA
00000000000000000000100000

For example to hide drive F the value for NoDrives = 20 in hexadicimal To hide all drives except C, D and E the binary value is 11111111111111111111100011 So the value for NoDrives will be: 3FFFFE3

Disable detection of USB Storage devices

To disable the detection of USB Storage devices paste the following in notepad and save it with a '.reg' extension.

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR] "Start"=dword:00000004

merge it with the Windows registry.

To re-enable the detection of USB storage devices use:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR] "Start"=dword:3

Write-Protect USB Drives

You can use this to prevent data theft through the USB port. Paste the following in notepad and save it with a '.reg' extension.

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies] "WriteProtect"=dword:00000001

Then merge it with the windows registry.

Disable Autorun on all drives

Many viruses spread through removable storage drives using the drives autorun feature. For example as soon as one inserts the USB drive an autorun.inf file that links to the virus gets executed.

To disable automatically running this autorun.inf file use the following steps:

1) If you use Windows XP Professional:

click Start>Run... type:

gpedit.msc and hit Enter. This will open a 'Group Policy' window. Expand: 'Computer Configuration' then expand 'Administrative Templates' Select 'System' and in the pane towards the right look for 'Turn off Autoplay'. Double-click 'Turn off Autoplay' and choose 'Enabled'. Where it says 'Turn off autoplay on:' choose 'All Drives' . Click 'Apply' and 'OK' Follow the same steps by expanding 'User Configuration'

2) In case your version of windows does not run gpedit.msc try the following method that uses the Windows Registry:

open Notepad and paste the following in it:

Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] "NoDriveTypeAutoRun"=dword:000000ff

Save the file with a '.reg' extension and double-click the file. You might be prompted to merge it with the registry. Agree to do so.

Note : if you double-click the drive it might still execute the autorun.inf file.

A safer option to open drives is to use the Windows Explorer View (WinKey + E). Or maybe you'll need to import this in the registry too: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdrom] "AutoRun"=dword:00000000

I'm not too sure but I guess the above tweak removes the Autoplay entry from the CDROM context menu.
