Change Windows Restriction for any Program

You can add and delete Windows features in this Key shown below. Zero is Off and the value 1 is On. Example: to Save Windows settings add or modify the value name NoSaveSettings to 0, if set to1 Windows will not save settings. And NoDeletePrinter set to 1 will prevent the user from deleting a printer.

The same key shows up at: 

HKEY_USERS\(yourprofilename)\Software\Microsoft\Windows\

CurrentVersion\Policies\Explorer so change it there also if you are using different profiles.

1.Open RegEdit

2.Go to 

HKEY_CURRENT_USER\Software\Microsoft\CurrentVersion\Policies

3.Go to the Explorer Key (Additional keys that can be created under Policies are System, Explorer, Network and WinOldApp )

4.You can then add DWORD or binary values set to 1 in the appropriate keys for ON and 0 for off.

This key has many other available keys, there is one to even hide the taskbar, one to hide the control panel and more. I'm not telling you how, as someone may want to play a trick on you. The policies key has a great deal of control over how and what program can run and how one can access what feature.

In the System key you can enter:
NoDispCPL - Disable Display Control Panel
NoDispBackgroundPage - Hide Background Page
NoDispScrSavPage - Hide Screen Saver Page
NoDispAppearancePage - Hide Appearance Page
NoDispSettingsPage - Hide Settings Page
NoSecCPL - Disable Password Control Panel
NoPwdPage - Hide Password Change Page
NoAdminPage - Hide Remote Administration Page
NoProfilePage - Hide User Profiles Page
NoDevMgrPage - Hide Device Manager Page
NoConfigPage - Hide Hardware Profiles Page
NoFileSysPage - Hide File System Button
NoVirtMemPage - Hide Virtual Memory Button

In the Network key you can enter:
NoNetSetup - Disable the Network Control Panel
NoNetSetupIDPage - Hide Identification Page
NoNetSetupSecurityPage - Hide Access Control Page
NoFileSharingControl - Disable File Sharing Controls
NoPrintSharing - Disable Print Sharing Controls

In the WinOldApp key you can enter:
Disabled - Disable MS-DOS Prompt
NoRealMode - Disables Single-Mode MS-DOS

To add or remove programs in the Registry
1.Open RegEdit

2.Go to the desired Key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunHKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServicesHKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\RunHKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices

3. Add a new String Value and name it anything you like
4. For the value data, enter the path and executable for the program you want to run.

By adding the value to the HKEY_CURRENT_USER hive instead allows the program to start only when that user is logged on.

If you add the value to the RunOnce key the program will run once and be removed from the key by Windows.
