Windows 7: Suddenly UAC and other things fail

01 Nov 2010   #1

Windows 7 Ultimate x86
Suddenly UAC and other things fail

I'm working with an Acer 9920 Laptop, with win 7 u installed. Until quite recently everything worked well. But now I have problems. For instance I want to install some software by doubleclicking on the msi file I see in Windows Explorer. After entering Admin credentials I get a message that the file I'm just seeing in WE cannot be found.
Similarly, when I want to edit extended system properties, C:\Windows\system32\systempropertiesadvanced.exe cannot be found.
Something apparently related is that when I want to start Eclipse which is a Java app the system fails telling me that no client JVM at xxx can be found.
When I log in as an admin everything seems to work right.
Maybe I changed something inadvertently, but I have no idea what this could be.

Are there any suggestions?

The first thing to try is a System Restore to before the problem started, see if that fixes it.
