By default parallels maps a drive on Windows 8 guest OS (z:\ to \\psf\Home). This drive is visible and usable when I'm running application that are not elevated. For application that are elevated the z:\ is not visible. I can still access \\psf\home but not z:\. I've tried the following: http://support.microsoft.com/kb/937624 But it does not help. Anyone solve this?
I had a same issue, but I could resolve the issue tentatively. Create a batch file containing the below: net use z: \\psf\Home Run the batch file as administrator by right-click on the batch file whenever I log in Windows 8. Then I can access the z-drive even when any application is elevated. I tried to make a shortcut to the batch file in shell:startup but made no success yet.
You can add a scheduled task to run on log in that will execute the bat file with elevated privileges. Then you don't have to remember to manually run the script.
