SUPPORT SCAN NOT SCANNING HARDWARE

@MAHESH SHARMA 

Please try disabling your security software (anti-virus, anti-malware).  These applications are known to interfere with the SupportAssist Hardware scan.  If disabling them works, then please go into those applications and add the following folders to exceptions (do not scan on access):

C:\Program Files\Dell\SARemediation; and,
C:\Program Files\Dell\SupportAssistAgent.

I hope this helps.  Have a great day.

Regards,
-Phil
