A user on the Windows Forum reported that,

Lately, I’ve been getting BSODs with the error “KERNEL MODE HEAP CORRUPTION” whenever I try to do something seemingly CPU-heavy (watching live streams/conferences, even trying to look at the Event Viewer). Following some experimenting, I noted that the KB4549951 update was not necessarily the cause of the BSOD because it happened even after I uninstalled it. I have recently updated my Intel display driver, but I can’t seem to roll it back from the Device Manager.

Numerous users are also facing WiFi connectivity problems after installing this update. In a post on the Windows forum, a user shared the WiFi Problems he has been facing coupled with the fixes he has tried so far.

Since the KB4549951 I have no more wifi on my computer.

I already tried all those, unsuccesfully:
– Uninstall update

– All the problem resolution software inside windows

– Restart the services linked to network

– Updating the drivers (drivers are up to date for sure now)

– Adding a usb wifi adapter, doesn’t work either

When I try to have help with the asking for help or send a comment on top right of parameter window, both tell me I’m not connected to internet but yes I’m with an ethernet cable, proof is I’m writing this post asking for help…

I try now to have the last update of Windows but Windows update is now stuck with error 0x80070422…

Some other error includes (Error 0x80073701)

Lastly, users are also facing other serious problems like decrement in performance, difficulties while opening windows defender, store games crash issues, USB-C monitor output problems, and several sound issues.

  1. Cant uninstall the update no option for it there please help my pc keeps crashing whenever i try to run a game even the light ones

  2. When I install the update and reboot, my premium-version of Microsoft Jigsaw reverts to free version, with all ads and reduced features. It offers to let me pay for a premium version upgrade – again! When I tried that for a one-month premium version (my premium version licence is actually for a year, doesn’t expire until November), it took my one-month money all right – but generated an error 0xc03f300d – and it still only plays as free version. Uninstalling the KB fixes the problem.

  3. uninstalled update and now i don’t get bsod on shut down. Tried everything I could think of to fix it and only uninstalling the update corrected it.

  4. Shailendra – to uninstall, go into a cmd or PowerShell shell as administrator and run this:

    wusa /uninstall /KB:4550945 /forcerestart

    That will uninstall it and restart.

  5. Hello,
    My HP Envy (purchased 10/2014) came with Excel and Word originally installed. (2013 version?). Now they are gone. The same with my sound. I was able to go to HP and correct the sound, but HP can’t help with retrieving Excel/Word. Did the updates delete these so that I have to purchase Office 365?

  6. folks this is the new Microsoft Id advise don’t update anything the techs working on this and the executives who order the updates don’t care about their customers just reformat and go to umbato lol

  7. The problem i have is that my pc doesnt start up anymore after this update. I get the blue screen of death. I can launch in safe mode and uninstall but it requires a restart at which point i get the blue screen of death so it is never uninstalled. When relaunching via safe mode i see that the the update has been unsuccessfully uninstalled and reinstalled again. Any subsequent restarts involve the blue screen of death. Not sure what else i can do aside from reinstalling windows 🙁
