Microsoft's latest Windows 10 update is bricking some PCs, causing them to enter an endless loop, unable to boot.
The update in question is the first cumulative patch for the April 2018 update to Windows 10, and users might want to postpone installing it until Microsoft solves the issue.
Windows 10 Update Bricking Some PCs
News of the issue first surfaced on Microsoft's official forums, where users complained of a KB4103721 update bug that sends some PCs spinning in a loop of failed boots. The bug doesn't affect all PCs, and Microsoft detailed which models are affected.
In response to user complaints, Microsoft took to its forums and expanded its KB4103721 patch notes to mention that some PCs with Intel SSD Pro 6000p Series or Intel SSD 600p Series might be affected by this bug, which causes them to stop working or puts them in a UEFI screen loop after the system restarts.
Microsoft has yet to offer more comments or solutions for this situation, so users took it upon themselves to find temporary workarounds until Microsoft fixes the problem. One such workaround would be to roll back to a previous Windows 10 version, unaffected by this bug.
How To Roll Back To A Pre-KB4103721 Windows 10 Version
Rolling back to a previous Windows 10 version might seem complicated at first for some, but it's actually a simple and straightforward process. Windows automatically creates a restore point before installing an update, so users need to get back to that point. To do so, access the Advanced Startup Options menu.
To enter the ASO screen, restart your PC and press F11 as soon as it starts powering up before it gets to display the Windows logo. If you missed this window, restart the PC again and repeat the move until you manage the ASO screen. If you can't access the ASO, check the website of your PC maker - some change the F11 default key to something else.
Once you've accessed the ASO screen, select Advanced Options > Go back to previous build. Windows should restart, roll back to the previous version before the buggy update, and start fresh.
To avoid the hassle, however, those with PCs equipped with the aforementioned Intel SSDs are advised to wait for a fix from Microsoft and only then install the latest update. Microsoft is expected to patch things up soon, but no timeline is available at this point.
