Problem: My laptop, which was working fine until yesterday, suddenly started giving the above warning meaning that you are not authorized no matter what I try to do (I am under Admin privileges), it says I can’t even open the control panel
, you don’t have permission.

Solution: If a spy, virus or malware did not cause it, do the following to overcome this sudden unauthorized problem, which can be seen especially in windows 7 and Vista
1. Here Download and install subinacl.msi from the link. (will be installed in the following path)

C:Program FilesWindowsResource KitsTools

2. Run cmd with admin privileges and switch to the top directory, then issue the following commands

subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f subinacl /subkeyreg_ministrators/subkeystrads= HKEY_CLUs %SystemDrive% /grant=administrators=f subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=system=f subinacl /subkeyreg HKEY_CURRENT_USER /grant=system=f subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=system=f subinacl /% /subdirectories%System f

Paste these codes to a notepad and click File – Save As…

Give any name in the window that opens (edit the file name and extension part as you wish) and save and run as .cmd

(into C:Program FilesWindowsResource KitsTools) then run this cmd
