Microsoft released a cumulative update KB3124263 last week, and it supposed to be just a regular cumulative update, with a few bug fixes and invisible system improvements. But, it actually caused a lot of problems to users who installed it.

Users are experiencing various problems upon installing the latest cumulative update, and some of them aren’t even able to install the update at all. So, if you still didn’t update your Windows 10 computer with the latest cumulative update, we’ll convey you the reported issues, so you’ll know what to expect when you install (or try to install) KB3124263 update.

Cumulative Update KB3124263 Reported Issues

Let’s start with the installation issue. Namely, some users reached Microsoft Community forums complaining that they’re unable to install the latest cumulative update.

“Have tried 3x to install Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3124263) but after restart tells me it was unable to install but no error code. Have tried with ZoneAlarm off but get the same results,” one of the users whose computer got impacted by the problem explains on the forums.

Although a few users reported this issue, Microsoft Engineers remained silent about it, which means that the solution is still unknown. We know that Microsoft never re-releases a cumulative update, which probably means that those who didn’t receive the update will have to wait for another cumulative release to receive all updates.

But even those who were able to install KB3124263 update weren’t safe from the problems. First thing that caught our attention is the problem with wireless connection after installing the update, as one user reported the problem on the forums.

“After todays update (14th Jan) KB3124263, the PC rebooted and WiFi failed to reconnect. It appears my Wireless Adapter will not now stay on. Everytime I turn it on, it turns itself off after a few seconds. The only way I can get it to stay on is to Uninstall it and then rediscover it and reconnect to my wireless. Then if the PC goes into hibernate or is restarted I’m back to square one. I tried rolling back the update but no difference. Anyone else had the same problem?”

Microsoft engineers weren’t so helpful in this case either, as they recommended a few usual solutions for solving Wi-Fi problems in Windows 10 (same solutions as the ones we listed in our article about problems with Wireless adapter in Windows 10), but these proved to be unhelpful. So, if you’re facing this issue, as well, we still don’t have a proper solution to offer you.

The update did even more damage to another Windows 10 user, who reported that some crucial features of the system lost their functionality after he installed the update.

“kb3124263. I also have had a problem installing the referenced patch. It disables Start. Banishes Cortana. And removes everything from the tray. MS Office apps no longer appear anywhere. I right clicked start and went to updates. I selected kb3124263 and deinstalled it. Restarted. Suddenly everything was back to normal functioning the way it apparently should be.”

So as you can see, the only known solution is to completely uninstall the update, but since Windows 10 will install it again, and you shouldn’t deactivate your Update process, the permanent fix is still missing. We can tell you to try our solutions for broken Start Menu and Cortana in Windows 10, but we’re not sure if these will work in this case.

For some users, it even disabled the update service for some programs, and the system itself:

“Microsoft seems to have soiled the bed with this update, a lot of people seem to be having critical issues with this update, for me, windows and steam can’t update, I guess I’d just say to do what you did before to get it working and see if there’s any way you can postpone the update.”

We have our own solutions for Windows Update problems, but once again, we cannot guarantee that these solutions will be helpful, as we’re not sure which is an exact cause of the problem.

As you can see, KB3124263 causes a lot of problems to users, a lot more than just a regular cumulative update should. If you experienced some problems that we didn’t list here, let us know in the comments. The same thing goes for solutions, so if you found a solution for any problem caused by this update, share it with us in the comments, it will surely help a lot of people.

Let me start. this is gonna be harsh.

Booted up my Laptop with preinstalled windows 10. I was greeting with
a blue screen and large font of windows installing new update. After it
finished with this update. My whole desktop had changed. over half of
my short cuts were missing. Important text
documents were missing that were saved on my desktop. I was furious!
and something called Onedrive now on my PC.. All of my I went to open
“My documents” folder.. OMFG! all of my folders (about 100gigabytes)
were missing!Not to mention all of my
important Firefox bookmarks are missing! (which took me many months to
find and mark!)

So.. I had to search and navigate to find these files that were in my
orignal documents folder.. I managed to find them buried within the C
drive under the user/name/documents location.. I proceeded to cut and
paste them back into the normal documents folder
where they were originally. I set all my shortcuts and files back onto
the desktop where they were supposed to be…. WELL…

I rebooted my pc and was going to proceed to start to reinstall all
of my programs that this stupid windows 10 update had removed,
rearranged and or moved WITHOUT my consent or warning..

PC rebooted.. GREAT! now i have a black background on my desktop.. my
shortcuts on my desktop Fk’n DISAPPEARED again! all of my files i had
just put into my documents folder?? GONE! AGAIN! and now they were
permanently GONE! all of my important files and
text documents, GONE!!

so OK OK.. I’ll call Microsoft tech support.. Didn’t Help.. Windows
10 software, windows 10 update. This screwed up my PC! and you guys want
to charge me $100+ to fix YOUR Fked up update? Now what the hell am i
supposed to do? your update caused me to
lose over 100 gig worth of extremely important and EXPENSIVE software,
text documents that cannot be replaced or restored.. OH btw on that
part…. This update.. It wiped out ALL Of my restore points.. all of my
Recovery options to take it back to an earlier

I should not have to be charged $100+ to fix what this latest update
has done to my pc and cause me to lose $100’s of extremely important
software, files, documents, pictures (which I will never be able to get
back!!!), music etc!!!!

It’s in my list of installed updates but it won’t uninstall.I can’t open notifications or settings,there’s no Windows update icon in control panel but the service is running.Those are the only problems that I’ve discovered so far,although there may be more.I’m thinking that I’ll end up reinstalling 10 because there’s no way to delete the update and no way to update anything even if a fix becomes available.Any more crap like this and I’ll go back to 7 and stay there until support for it runs out.Then I’ll either switch to Linux or buy a Mac.
