Yet another huge issue caused by the latest Windows 10 April 2018 Update 1803. The symptom of this problem is that after applying Windows 10 update, your computer boots into a blue screen asking you to choose your keyboard layout.
After choosing a keyboard layout, you are given a few options similar to the following:
- Windows Rollback
- Windows 10 on Volume 2
- Windows 10 on Volume 3
If you choose Windows Rollback, your PC will restart and startup into the same choose your keyboard layout blue screen again (we are calling this Windows rollback loop today). If you choose latter two options, you will be booted into Windows 10 black screen after login with no icons and only a working cursor.
In the previous blue screen, you will also be given options to Troubleshoot the Windows 10 startup where you will have access to tools such as command prompt, system restore, Windows 10 reset, startup repair and rollback to previous version. Try the workaround below first, only then you decide if you want to restore or reset your Windows 10.
