Accidentally Delete Windir in System Variable

Question

Hi,

I accidentally delete WINDIR when I change the setting in System Variable.

Now, I can't open any applications. For example, I can't run the administration for Command Prompt, or open Registry Editor.

Could you help me to reset WINDIR in System Variables?

Thanks.

Hi Gustavo,

Thank you for replying.

I did try to restore my system, but it said 'the system doesn't have anything to change.

I couldn't reset my PC either and I couldn't access the 'Edit The System Environment Variables'.

Do you have any other ways?

Thanks.

Answer 3

What do you show in the registry key shown below?

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment

Answer 4

Hi Saltgrass,

I couldn't open Registry Editor.

I try different ways to open it but it doesn't give me access. Such as, Using Windows + R and typing Regedit or searching for Registry Editor.

Besides, I couldn't open Command Prompt as administrator.

If you need other information, please let me know.

Thanks,

Are you an administrator on that system. The Winkey + R should be able to open the Registry editor. If you aren't admin, then it is understandable why your options for the Environments are greyed out.

You might also try changing the directory to were regedit is actually kept.. Go to C:\Windows\ and double click the regedit or right click and select run as admin. Or try C:\Windows\regedit.exe in the run box.
