No access to W7 main profile

Windows 7 Enterprise desktop is black and icons on desktop and taskbar can't access shortcut destinations. Can't change desktop background t normal.
MS Excel icon on desktop doesn't function at all. When starting MS Excel manually, there doesn't seem to be any problems.

Lightroom can't start because cannot create files in temporary file location c:\users\...AppData\Local\Temp

Pinned Windows Media Player on the Taskbar gives an error: Can't open this item, it may be removed, deleted and etc.

At first glance Advanced security settings of Users\user folder are correct.
Looks like user doesn't have access right to profile. Is there any ideas how to fix?

Thanks!

Still the same problem - Windows 7 Enterprise computer not accessible and there seems to be no knowledge available how to fix :-( Microsoft help just asks your name, address and money but doesn't fix anything - do we really want this???
