Several Windows 10 users are reporting a wide range of issues after installing Windows 10 KB4549951 cumulative update. Others still are reporting error messages when they try to download and install an important security package released on Tuesday, via Windows Latest.
Microsoft faced heavy criticism after the company shipped, what many users perceived to be, a botched update for Windows 10 in October 2018, and now it looks like Microsoft has released one more lack-lustre, bug-riddled update.
In Microsoft’s forum and Feedback Hub, many users have reported that Windows 10 installation issues are once again back with KB4549951 and this apparent bug is preventing people from keeping their devices up-to-date.
Despite these issues, it is imperative that users keep their machines properly updated with the latest security patches. Unfortunately for many, this is another update that fails to install with generic error messages like 0x8007000d, 0x800f081f, 0x80073701, etc.
As of yet, it is still unclear why Windows 10 updates are failing to install for some users and Microsoft still hasn’t acknowledged or documented the issues.
If you have already followed the traditional workarounds available on the internet and nothing seems to work to resolve the issue with Windows Update, you may want to consider performing a clean installation of Windows 10. To perform a clean installation, you’ll need to download ISO images and reinstall Windows 10.
However, this method comes with apparent risks, such as losing user data on the machine – so if you’re considering this, you should ensure your data is backed up.
Further Windows 10 KB4549951 Issues
Other than stopping users from downloading important updates, this patch has also shipped with broken Bluetooth, WiFi, connectivity problems, BSOD, poor system performance, and even complete system crashes for some users. Not every user is being affected by these issues, however, and many are presenting with only particular problems.
“I wanted to let you know that after installing this update “KB4549951″ my device no longer has a Bluetooth adapter according to Windows (which of course is false since it still worked yesterday before installing this damn update,” one user told Windows Latest in an email.
“I updated (KB4549951) my Windows 10 on 15.04.20. After updating, Bluetooth stops working. Now Bluetooth is not showing in Device Manager. I tried to uninstall Updates but still, it is not showing. What to do now. My Laptop supports Bluetooth,” another user reported the same issue in Microsoft’s forum.
As of now, it appears there is a distinct compatibility issue between the Bluetooth Driver and this latest Windows 10 update. Users who are encountering this problem should roll back to a previous version of Windows and reinstall the driver if it still isn’t available.
This update is also reportedly causing the dreaded “Blue Screen of Death” for some users.
The BSOD signals a complete system crash and is reserved for major failings in software.
One victim wrote that their MSI computer booted with a BSOD after applying this update.
“I was hit with the infamous blue screen ( YOUR DEVICE RAN INTO A PROBLEM AND NEEDS TO…..) with each time a different stop code,” the user explains.
“I noticed that after installing the KB4549951 update, I get BSODs with the error ‘KERNEL MODE HEAP CORRUPTION’ whenever I try to do something seemingly CPU-heavy (watching livestreams/conferences, even trying to look at the Event Viewer). I did some experimenting and noticed that the update was seemingly the cause of the BSOD – everything else seems to be fine,” another frustrated documented the bug.
As the world turns inwards with COVID-19 on the rise, a buggy update is the last thing millions of Windows users need to face as they attempt to work from home.
