After that there was some 'computer cleaning' which unfortunately we don't know details of.
Well, it sounds like "the cleaning" screwed up the WMI service -- maybe beyond repair. Either have whoever did the cleaning undo that cleaning, or have them fix the many group policy settings that cover things like access for users to communicate with the WMI service.
From TurboActivate.h:
/* MessageId: TA_E_COM Message code (in Hex): 0xB Message code (in Decimal): 11
MessageText:
The hardware id couldn't be generated due to an error in the COM setup. Re-enable Windows Management Instrumentation (WMI) in your group policy editor or reset the local group policy to the default values. Contact your system admin for more information.
This error is Windows only.
This error can also be caused by the user (or another program) disabling the "Windows Management Instrumentation" service. Make sure the "Startup type" is set to Automatic and then start the service.
To further debug WMI problems open the "Computer Management" (compmgmt.msc), expand the "Services and Applications", right click "WMI Control" click "Properties" and view the status of the WMI.*/#define TA_E_COM ((HRESULT)0x0000000BL)
