Windows 10 freezes up 3 minutes after start up since recent update

If the system freezes a few minutes after startup
If login works but the PC consistently freezes a few minutes after boot (for example, around 5 minutes) following an update, a scheduled task may be involved. One reported case of Windows 10 freezing a few minutes after startup was traced to the scheduled task:
Task Scheduler → Task Scheduler Library → Microsoft → Windows → PI → Secure-Boot-Update
Disabling this task stopped the freezes in that scenario. To try this workaround:

1. Boot into Windows (or Safe Mode if needed).
2. Open Task Scheduler.
3. Browse to Microsoft → Windows → PI.
4. Locate Secure-Boot-Update, right‑click, and choose Disable.
5. Restart and test whether the freezes at login/shortly after login stop.
   This is a workaround; once Microsoft releases a specific fix, re‑enable the task and install the updated patches.
