Windows 10 - Defender Offline Scan not working

Was this issue solved? I am having the same problem - additionally when in safe mode (including safe mode with networking) - windows defender has no options to run any scans

Hi Ole,

My Windows 10 machine is version 1703 (OS build 15063.540)

2017-08 Cumulative Update for 64bit KB4034674

I have not been involved with the problem that you describe. Is it possible that

there may be remnants of your old antivirus present? If you dare, you might

search your Registry. CAUTION: changes can be fatal!   Good Luck, Glen

Hi Cass,

The current question is; Exactly what should WDO look like during an offline

scan. Before Cumulative Update 2017-06 KB4022716 and 2017-07 KB4025342,

the "splash screen" would display, indicating that WDO was preparing to run,

and then the WDO GUI would display during the scan. No doubt, scan running.

I never paid any attention to how long the "splash screen" was on before, but

on my machine it runs for two minutes now. That doesn't seem long enough

for a scan. But it does seem more than enough to prepare!  

I am currently trying to get the answer. Please see the LINK

Regards,  Glen

Hi,

Apologies for the confusion.  The problem that I posted is related to the original question on this thread from A. User (I appear to have the same problem):

"Win Defender Offline Scan not starting, not rebooting, nothing happens (?)"

Regarding the problem posted by Cass, I am not sure what is going on.  I have two other devices running Windows 10 1703, and I get the same exact response i.e. I only get what looks more like a splash screen, and then it reboots again.  

GlenProuty - what version of Windows 10 are you on?

My sense (for this second issue) is that there are two possibilities, given that many seem to have this problem:  1) On recent builds (i.e. 1703) this is "normal" i.e. the splash screen is actually the scan itself or 2) on recent builds, WDO is fubar and not working at all, and MS will have to acknowledge and fix this problem on future updates.
