The most recent cumulative updates for many versions of Windows 10 have a bug that's causing some PCs to produce a black screen after they've been installed, potentially leading some users to worry that their system might be seriously broken - but fortunately, the cure is simple to apply.

Windows Latest reports that the problem can occur to those running the April 2018 Update in addition to those found on the October 2018 Update, although it apparently only affects a small amount of those users. As stated, the issue crops up after getting the latest patches for that operating system, and rebooting laptop computer post-installation.

Microsoft observed: "We are investigating reports that the few devices may startup to a black screen throughout the first logon after installing updates."

Fortunately, all you have to do when confronted with said black screen is to press Ctrl + Alt + Delete together, click on the Power button (lower-right) and select Restart. Your PC will reboot, and also the desktop should then appear as per normal.

So this is almost not a huge problem, but nonetheless, it could cause some heart-stopping moments since the last thing you want to see post-patching is a blank screen instead of your desktop.

Microsoft says it's working on an answer right now, so hopefully this isn't a glitch which will hold off for too much time.

Bluetooth blues

Meanwhile, in other Windows 10 bug news, there's an additional issue affecting the famously gremlin-plagued October 2018 Update, also it relates to Bluetooth devices.

Specifically, it's brought on by cumulative update KB4494441, that was actually deployed in May having a number of important security countermeasures. However, this update causes issues with certain devices using Realtek's technology.

As highlighted by Softpedia, Microsoft explains: "Devices with Realtek Bluetooth radios in some circumstances might have issues pairing or connecting to devices."

If you are experiencing such difficulties, then the good news is that Microsoft promises a fix will be delivered later in June, so either now or next.

It hasn't been a lot of fun for Bluetooth devices where Windows 10 is concerned, since very recently we found out that Microsoft is blocking certain bits of hardware from wirelessly connecting.
