System Restore has been turned off by group policy

I get the error message:

System Restore has been turned off by group policy. To turn on System Restore, contact your domain Administrator.

Nor does my task manager open, as my administrator disabled it.

I'm the only one who uses this computer, my account is the master account.

Regedit and CMD don't work either...

copy/paste these into Start -> Run

for CMD:
REG add HKCU\Software\Policies\Microsoft\Windows\System /v DisableCMD /t REG_DWORD /d 0 /f

for regedit:
REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f

Task Manager:
REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableTaskMgr /t REG_DWORD /d 0 /f

For System Restore:
* Click Start, Run and type REGEDIT and press Enter
* Navigate to the following key:
HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\SystemRestore
* In the right-pane:
* Delete the value DisableConfig
* Delete the value DisableSR
