I noticed that commands weren't working in my command prompt. I tried rebooting but still the same problem. Eventually after looking in this forum, I found out that my PATH variable was effectively deleted and the only entry is one directory of the program I was installing. I uninstalled it, but now the PATH variable is empty. How do I restore the path to an old version from say yesterday?
I tried the methods in How to restore the Path environment variable I deleted? but I have no entry ControlSet002 in Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment
