If after uninstalling the update but the issue isn’t resolved, try the next solution.

2] Perform System Restore

As you’re unable to log into your Windows device and get to the desktop, you can perform the System Restore method when you can’t boot to the desktop.

This System Restore operation reverts your system back to an earlier state before the update installation that is causing issues at the moment.

After that, you may Hide that update or Pause Updates for say 7 days – which gives time for Microsoft to release an updated fix.

3] Reset Windows 10

Here again, as you can’t get to the desktop on your Windows 10 device to perform a reset, you can try the Reset method from Advanced Options. Here’s how:

Turn off and start the computer.
Press F11 to enter the Windows Advanced Startup Options menu.
Select Troubleshoot.
Select Reset this PC.
Select Keep my files option..
Follow the on-screen instructions.

Make sure you make Windows 10 save your existing files and data.

Hope this helps!
