Curious what you have seen in Windows 7 vs XP with regard to the number of WMI failures.
Certainly think it is lower just wondering if anyone has done stats?
Tuner log on machine where details are reported inaccurately:
#Winscan: # winscan 8.2.00
#Winscan: Fall back to non-wmi as IWebLocator object creation failed.,The Specified module could not be found
We have used WMIDiag 2.1 -Download The WMI Diagnosis Utility -- Version 2.1 from Official Microsoft Download Center
Also used the following from MS to reset WMI as a bat file run with elevated rights.
sc config winmgmt start= disabled
net stop winmgmt /y
for /f %%s in ('dir /b *.dll') do regsvr32 /s %%s
sc config winmgmt start= auto
net start winmgmt
for /f %%s in ('dir /s /b *.mof *.mfl') do mofcomp %%s
Are you doing anything to find/resolve WMI issues?
