Win10 10061 black screen blue screen emergency patch KB3055415 how to install?
Windows 10 Build 10061 brings a lot of new features and improvements, it is worth experiencing, but naturally there are a bunch of bugs, which can be tolerated, and the big one can't stand it.
For example, when you lock the screen, you will find that the screen is black or blue, leaving only one mouse cursor swaying, but there are no buttons or dialogs that can be manipulated.
At this time you either restart the computer directly, or press the Ctrl key to blindly enter the password. The former will naturally make your current work in the middle, the data is lost, and the latter may not really know, even if you know the operation is a bit difficult.
So Microsoft urgently released a repair patch KB3055415, which solved this problem urgently. Build 10061 users can now download updates on Windows Update and restart after installation.
