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?

Had the same thing happen to me after I installed Delphi 7 ent. Luckily I'm running Windows 7 and some other fella showed me the way at [another thread](http://superuser.com/questions/265532/how-to-extract-environment-variables-from-system-restore-point-windows-7-64-bit)! – k9dog Jan 19 '13 at 21:55

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"

Windows XP System Environment Variables
The key is
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
The value is
Path REG_EXPAND_SZ %SystemRoot%\;%SystemRoot%\system32\;%SystemRoot%\system32\wbem\
That's it.
