As expected, April’s cumulative updates – KB3147458 & KB3147461 – have some bugs associated with them which are causing issues for some minor set of Windows 10’s userbase. More details after the bump.
When your software is used by hundreds of millions of people, you are bound to have users find pesky little, difficult-to-reproduce bugs that your Quality Assurance team couldn’t find.
Such is the case with Microsoft’s Windows 10 – used by over 270 million people worldwide. So, whenever a new cumulative update releases, we hear reports of users finding troublesome bugs and issues that make using their PC a bit of a problem.
Yesterday, Microsoft released April’s cumulative updates KB3147458 & KB314746 for Windows 10. At the end of the post, we suggested users wait a couple of days before downloading the update. It appears our suggestion was correct, since we are hearing reports of issues in KB3147458 – the cumulative update specifically for Windows 10 1511 Threshold 2 (TH2) users – not in KB3147461 as per our observation.
Update: You should go for the latest Windows 10 cumulative updates. They have many bug fixes and improvements.
KB3147458 Breaking USB mice, Not Downloading, Messing Up Programs & More
Some users of KB3147458 update are reporting it breaks their USB mouse. trulygenericname1 over on Reddit notes Windows 10 detects their mouse for five seconds before throwing recognition errors and shutting off power. The comment received six upvotes, which suggests some other users are experiencing it, too. In related comments, people say their keyboard wouldn’t work either (though I’m not sure how they then typed their comment. Hmmm…)
DeltaF1 says Cortana’s reminders aren’t working as well anymore; apparently she keeps setting all reminders for the next day and when you ask her for changing the time to today, she says she can’t time travel.
Slad74 says the cumulative update broke their PC “just like the last two cumulative updates”.
Another user Jakobus3 couldn’t download the update at all in the first place. They say they’re stuck at an unspecified older version of Windows 10 10240 – the original Threshold release in mid 2015. We also heard reports of KB3147458 downloading properly, but failing to install.
Other users claimed the new update would cause compatibility issues with their displays.
Over on Microsoft Community, we’re hearing users say the April update has ‘messed up’ their programs. One user chimed in saying that right-clicking on any executable file crashes Windows Explorer.
Temporary Solutions To All Issues
That’s the gist of the issues we’ve come across so far. We will update this post, and share fixes that solves these issues as we dig deeper into the situation. Until then, we recommend uninstalling the KB3147458 or KB3147461 – whichever of the April cumulative update you’re having trouble with – from your Windows 10 PC.
To uninstall a cumulative update, go to Control Panel > Programs > Uninstall a program > View Installed Updates. From here, you should be able to see the latest build in the list. Right-click on it, and select Uninstall to remove it from your PC.
If you had to do that, take this as a lesson not to immediately install the latest update. Wait a bit before taking the dive. Prevention is better than cure!
