I experienced an issue with Windows today. After unsuccessfully trying to fix the problem, I fully reloaded Windows 7. But now when I open Paralells, with Windows 7, I can't access any of the files between the Mac and Windows. For example, I copied a file on my Mac desktop, which used to appear on the Windows desktop too, but now it does not. Options/Sharing shows that the files should be accessible. (I'm running Parallels 10 on Yosemite.) Any help?
Glad you have it resolved by reinstalling Parallels Tools. Feel free to reach out anytime. We are here to help!
