Environment Variables in Windows 10  

Actually, no. That's how I ran into the issue. I use an SSD drive for windows but it is small so my user root is on D. When I tried %Homepath% in a command line parameter, it did not work. I believe %Homepath% usually works because a typical installation defaults to C: not D: as in my case. %userprofile% is equivalent to %homedrive%%homepath% and will work more generally.

BTW, thanks for the article. I couldn't remember the ENV variable "homepath" and learned a few new ones at the same time.

I don't see anything wrong with how it was done either.

I wonder if it is related to a problem I had in Vista once where a whole load of the environmental variables wouldn't work such as %APPDATA%, I eventually found some registry items that had been removed (I'm not sure by what) and once I put them back all the other variables started working

I don't know what this is, but it seems that someone that does may find it useful....
