Subject: [PATCH] Fix 1024 character limit with setx

setx will automatically truncate the PATH to 1024 characters if it is longer than that. It also mixes the local user's path with the machine-wide path, which is no good.

Unfortunately, the only way around this is running PowerShell to set the PATH manually.
