Class Not Registered for all sections

I've been using Speccy for a while both on this desktop and my laptops. All use Windows XP3, all use Avast! A/V etc.

Recently (I don't remember when) when I opened Speccy for each and every field I see "Class not Registered" entered for

the results. This is strange. I thought maybe the "upgrade" that I had gotten might have been bad, so I have re installed

1.20.xx and even 1.02.xx yet all show the same results.

HP workstation xm8200

3.2ghz processor,

Don't know what or where to look.... screen shot here,

It may be to do with the WMI service (Windows Management Instrumentation)

Old thread here which may be worth considering.

Or try to run the program "Windows Repair" (www.tweaking.com) and make sure you tick the box "Repair WMI".
