released the cumulative updates for Windows 10 version 1803
and it appears to be causing a number of issues on some
systems. Windows 10 KB4103721 bricks PCs and the
installation results in a black screen on a number of
systems. KB4103721 is the first patch for Windows 10 April
2018 Update and it was supposed to fix all the reported issues.
A number of users on Microsoft’s Community forums reported that
there’s a problem with KB4103721. The Windows
10 KB4103721 is causing black screen and the system fails
to boot. The only workaround which works for most of the users
is to restore the system to the previous version of Windows 10.
While the first cumulative update for Windows 10 April
2018 Update (version 1803) includes bug fixes for the reported
issues, it appears that there’s a bug in KB4103721 which
is bricking PCs and preventing them from booting. It is,
however, worth noting that not all systems are impacted.
There’s indeed a problem with this cumulative but it’s hard to
determine a fix or the pattern at this point. In most of the
cases, restoring the PC to the previous version of Windows
helps and the PC finally boots to the login screen.
While several users have confirmed the bug on Microsoft’s
Community forums, the software giant hasn’t acknowledged the
installation issues yet.
Recover PC from the black screen after installing Windows 10
While the official workaround is not available at the moment,
most of the users have managed to fix the installation issues
by restoring the system to a previous point or downgrading to
Windows 10 Fall Creators Update (version 1709).
You can only restore your PC to the previous version of Windows
if you haven’t touched the windows.old and $windows.~bt folders
after the upgrade.
The recovery process basically takes your PC back to an
earlier point in time. Microsoft says that it is generated
every time you install a new Windows update or driver. While
restoring won’t affect your personal files, but the process
will remove the apps, divers, and updates that you installed
after the restore point was made.
To restore your system, you may need to enter the Advanced
Startup. To enter Advanced startup and fix the installation
issues, do the following:
- Hit F11 as soon as the computer powers on. This can get you
to the Advanced Startup Options menu, but it also depends on
the manufacturer. And if nothing works, the PC should
automatically boot to Advanced Startup after several failed
- In Advanced options, click “Go back to the previous build”.
- (Or System Restore if nothing works).
You can also create the installation media on your second PC
clean install Windows 10 April 2018 Update.
Microsoft is yet to acknowledge issues with this cumulative
update. We’ll be keeping an eye on the forums and update the
article when the official workaround is available.
