(Basically I need to access FTP site and want to setup IIS)

I have set path also in Environment variable
Also cannot do anything from Registry Editor

My PATH in Environment variable is

Hi @AkDev

There are many reasons for this problem, you can try the following solutions:

1. Use the System File Checker tool to troubleshoot missing or corrupted system files on windows.
2. Open a command prompt with admin rights, run this new DISM command to fix this corruption: DISM /Online /Cleanup-Image /RestoreHealth
3. If it still does not work, please perform system restore according to the version of your windows version.
