I installed an application that screwed my PATH variable. Now I cannot run anything from the command prompt. Is there any way I can restore PATH variable?

Got the answer on Experts Exchange. Here is the excerpt:

Start regedit and check for the "Path" value in HKLM\System\ControlSet<xx>\Control\Session Manager\Environment (replace <xx> with all numbered ControlSet entries that are present. No need to check CurrentControlSet, it's one of the ControlSetxx keys, and you won't find anything under there.)

These are the "Last Know Good" configurations; if you're lucky, there's still one left that has a path variable.

If not, the bare minimum required is this:

C:\WINNT\system32;C:\WINNT;C:\WINNT\System32\Wbem

The default environment variables are stored in the registry under following key

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment

Set the path variable to its default value here:

"C:\Windows\System32\;C:\Windows\;C:\Windows\System32\Wbem"

A system restore should restore the PATH variable.

Did you use google at all?

Note: If you had other applications installed before you damaged your path variable, you need to make certain they are also placed on your PATH.

The path variable is a simple list, with semicolon delimitation.
