Ok..that's good- you know something to try next time..
FYI I had this same issue when I was using any browser (for anyone that reaches this in a search).
It turns out it is the wireless driver, when I tested that theory by plugging in the Ethernet cable, the problem does not occur. The machine also comes back from being in sleep mode and gives the user/pw prompt immediately instead of hanging like it used to.
My built in wireless card is an Intel Dual Band Wireless_AC 7265.
I'm going to try and update the driver after an uninstall/reinstall and if that doesn't work, I'll try a USB wireless card with new driver.
I notice this sort of problem after Windows has about a month of uptime. When screen saver (specifically monitor shuts off to standby via Windows power management), normally system is idle and monitor LED turns amber and screen is off. But after some weeks, an anomaly occurs where monitor LED stays green, but backlight shuts off, then flashes on/off every few seconds. Simultaneously, there is lots of disc activity, as seen by flashing disc LED. When I press a key to 'wake' the PC, I see that all processor cores in Taskman are showing 100% spikes and is very dynamic up/down graphs.
Rebooting fixes the problem for several weeks until it returns eventually. Just another Windows 10 quirk?
I dealt with this issue for months , come to find out Microsoft has a known issue with the Windows photo viewer causing high cpu usage and just has refused to fix it.
This is what fixed it for me .....
Solved: Shell Infrastructure Host Having High CPU Usage
After this my cpu went from usage in the high 90's all the way down to the low 20's
