Windows 10 has had its fair share of failings recently but none are as damaging as the latest update, which is causing Blue Screen of Death errors and deleting files. 

Users who downloaded Windows 10 KB4549951 are reporting a range of problems, from system errors to personal files being deleted without permission, Windows Latest reported. Microsoft released the latest version of Windows 10 on April 14 to patch a number of security problems. 

Soon after, users started complaining that their laptops were showing the Blue Screen of Death, which typically signifies a serious hardware or driver problem. A portion of the users hit by this issue experienced a complete system failure. 

Windows 10 file deletion bug

If Blue Screen of Death sounds bad, it gets even worse. The update now appears to be moving and deleting files. 

As Windows Latest reports, users are reporting that documents, pictures, files and personal settings are vanishing from their system after installing Windows 10 KD4549951. 

“This update is a disaster. It deleted my files, pictures, documents saved in system drive and as well as my apps which I downloaded from Windows Store,” one user wrote in the Windows Latest comments.

“I guess this latest update happened last night. I switch on this evening and all my personal settings are deleted. No bookmarks in Firefox or Chrome. I don’t want Bing or Internet Explorer. Wallpaper removed,” another Windows 10 user wrote on Microsoft’s forum.

This isn't the first time we've heard of files getting deleted off of Windows 10 PCs. In February, Windows 10 version KB4532693 was causing the desktop to return to its default settings, and in 2018, the now-defunct Windows 10 October update was erasing PC users' documents, photos and music folders. 

What to do

Your best line of defense against Windows 10's update bugs is to revert to an older, more stable version of the operating system. We don't typically advise uninstalling an update meant to fix security issues, so only do so if you're experiencing problems with version KB4549951. 

If you fall into that category, open your Settings, press "Update & Security" and choose "Windows Update" on the left side. 

From there, click "View update history" and find the KB4549951 to uninstall. Once you've done that, you'll need to restart your PC.
