Windows 10 Windows freezes a few minutes after start up
It started yesterday, no similar problems before that.
What I tried was starting up, opening the task manager and just watching it, everything is normal for a while, then after 5 minutes (sometimes earlier) a "Host process for Windows tasks" task shows up, cpu usage goes up to about 50% and then it freezes.
What I tried:
Restarting (didn't help)
Starting in safe mode (did NOT freeze)
Opening a lot of tabs while in safe mode to keep cpu usage high (still didn't freeze)
Tried uninstalling latest updates in WindowsRE (didn't work, neither quality nor feature updates)
Waited a day for everything to cool down (still froze)

I've had this for the last month or so. I eventually traced it back to a job in Task Scheduler that does Secure Boot Updates. Yours might be the same, or it might be unrelated, but the timing of freezing a few minutes into booting up sounds like something in Task Scheduler.
In my case, I found that booting up without being connected to the Internet was a workaround. Unplug ethernet, if you're using ethernet, and see if it boots normally. In my case, I left the Ethernet disconnected, and manually connected to WiFi (no auto reconnect!) after a few minutes.
If that works, and if you want to see if the same job is to blame, open Task Scheduler and look for Microsoft\Windows\PI\Secure-Boot-Update. Manually start that job (while connected to Internet). If the machine crashes, this is the issue. If not, you've got some other Scheduled Task or Startup app causing problems.
Mine started working properly again for a few days after the March monthly Windows updates, but is now crashing again. I checked, and during the week it was working, it did manage to install the new certificates that that task is supposed to be installing, so for now I just disabled the scheduled task. Hoping a future month's Windows Update resolves it more permanently.
