Když všechno selže, zkus tohle:
Rebuild your Windows Management Instrumentation (WMI) Repositiory where the system information is stored.
On the Desktop, right-click My Computer, and then click Manage.
Under Services and Applications, click Services, and then stop the Windows Management Instrumentation service.
If asked about stopping other services (Windows Firewall/Internet Connection Sharing (ICS)), respond in the affirmative. You can consider disconnecting from the Internet before stopping the Windows firewall.
Delete all of the files and folder that are in this folder:
c:\Windows\System32\Wbem\Repository
(or %SystemRoot%System32\Wbem\Repository)
They will be recreated shortly after rebooting.
Immediately restart the computer so the Firewall will be restarted.
Verify the WMI Service has been restarted
After the system restarts, click Start, Run and in the box enter:
rundll32 wbemupgd, UpgradeRepository
Click OK to rebuild the contents of the Repository folder.
This will repopulate the Repository folder with fresh information.
Try your msinfo32 operation now.
V českých Windows by se to mělo jmenovat Služba WMI.
