Win10 Preview 10061 is updated to solve black screen Bug

Computer Store News: Microsoft launched a small update (KB3055415) for Win10 Preview 10061 to solve the lock screen bug. The problem is that a black screen with a mouse cursor may appear, and Microsoft has provided some workarounds and fixes. Build 10061 was recently released to the Windows Internal Plan participants of the “Fast Ring” channel.

Microsoft explained that, when you log in to the Windows 10 Technology Preview Build 10061 and return to the lock screen, you may only see the black screen with the mouse cursor. Pressing Alt + Tab or Ctrl + Alt + Del has no obvious effect. "If you are experiencing this problem and cannot log in to Windows, try these solutions:

1. Black screen Next, press the physical Ctrl key (in this case, any virtual keyboard does not work. After pressing the Ctrl key, the mouse will move to "Invisible" login password input box)

2. Now enter the user password and press Enter, so you can log in to Windows and the desktop will appear.

3. If you are unable to log in because you entered the wrong password, press Enter again, then re-enter the password and press Enter.

4. If you have successfully logged in, go to Windows Update to download and install the KB3055415 update.

Users who are experiencing this issue can patch the issue through the Windows Updater after entering the system.
