What is the default Windows %PATH%?

The path is based on programs installed on the computer, so there is no "default path." However, the Windows minimum path is often the path below.

%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem
Note

Keep in mind that as you install programs, the path is updated with the paths for the newly installed programs. So, if you have erased your path after installing other programs, those programs may be affected.
