Visual Studio 2012 (or an update to VS2012 maybe) messes up the HKEY_CLASSES_ROOT\VisualStudio.xxx.11.0 ACL's, resulting in an "Access Denied" error. When searching for the issue, I can see numerous people are experiencing different types of errors, related to "Access Denied" from the registry.
For me, the error is that I cannot add any files to my TFS Server, because it needs to read those registry keys.
The worst part is, that I cannot use regedit (or a script), to reset the Access on the registry keys, because that also results in an "Access Denied" error. Reinstalling VS2012 does not help either, the error persist.
No one in forums, etc. has been able to resolve this critical issue, or offer any workarounds, so now I am hoping that you guys can provide some means of help.
