Corrupt registry value's in hkey_classes_root\clsid

I have a weird problem on a lot of machine's wich i cannot
solve.

As my job as a technical support provider i see a lot of
strange stuff, but this one I just cannot solve.

On a lot of computers at my location I have the following
problem.

Under the hkey_classes_root\clsid key there are a lot off
entry's

On a number off those entry's I have some corrupted
regisrty key's.

For instance HKEY_CLASSES_ROOT\CLSID\{00020420-0000-0000-
C000-000000000046}

Normaly you will see there two key's :
InprocServer
inprocserver32

(Default)oleaut32.dll
ThreadingModel "Both"
