Windows 10: After start seeing desktop icons flash

Couple times today, I've seen the desktop icons all flash/flicker for a micro second. You know the type when something installs and desktop refreshes. But of course I am not installing anything. So possibly something background happening/updating. Is there some kind of process monitor/log that I can open to determine what happened?

Untitled messages after start up

Thanks for your help, I have now restarted the laptop only to find a black desktop and flashing icons! These do settle down after a while but appear to start flashing again when file explorer is selected.

 

Why do my quick launch icons flash when I click on the Chrome quick launch icon? Win 10

Before I start the Troubleshooting, I just wanted to tell you that the Google quick launch icon is the only quick launch icon that causes the other icons to flash. As far as desktop icons go, the Google Chrome desktop icon is the only one that makes that
quick launch icons flash. Sometimes both Google Chrome icons will cause some, or all, of my desktop icons to flash.

I'll try the Troubleshooting method as soon as I get the chance.

Thanks.

 

Totally speculating but maybe it's Windows defender causing it. I notice the defender icon since anniversary update now sits handily in the system tray. After a login I notice after a few minutes it obtains an exclamation Mark purely because I haven't ran a scan in a while. I wonder if it's that which causes the desktop icons to flash/ re draw in a micro second. I've just ran a quick scan to eliminate that prompt/exclamation to see if it stops this.

woukd be good to know how to see the timeline of updates, events , installations though. I know there is a way where it displays in chart format. Before the recent store update it was the only way to see what apps were updated and when (if the update process was on auto). But I cannot remember or find what it is one has to launch to see it

 

I found the cause of the flashing icons. There was an office update early yesterday and now this is seemingly running all the time.

i did re enable onedrive to run at Windows start yesterday which in turn also seemed to add icon for office upload centre to system tray. Is it anything to do with that

EDIT : I notice this is happening on our other machine too so it must be to do with the office 365 updates yesterday morning. Question is, is it normal to now run this at every boot/login and what does it do?
