The battle between Windows 10 users and Microsoft is reaching unprecedented heights, as exhibited by one user’s unusually frustrating experience. After months of refusing to upgrade to Windows 11, which was offered to him on his Windows 10 PC, djseifer on Reddit was shocked to discover that his PC made that decision for him. When he left his computer unattended to take a shower, it went ahead and upgraded to Windows 11 without asking. The Reddit thread has attracted lots of attention (over 5,500 upvotes) and amusing comments, ranging from “That’s why I never take a shower” to “You’re being upgraded, please do not resist.” Can Microsoft force Windows upgrades? What’s puzzling here is that it shouldn’t actually be possible for Microsoft (or your own PC) to initiate an upgrade from Windows 10 to Windows 11 unprompted. As the affected user himself writes, he was repeatedly asked to do so but refused the switch every single time. It’s therefore more likely that this is either a bug or that the user accidentally agreed to it before going to take that shower. In any case, the damage shouldn’t be too great since users can always revert back to the previous version after upgrading to Windows 11. This rollback can be done either through the official channel , which is available for 10 days after an upgrade, or with free tools that also significantly increase the support period for Windows 10 . How to prevent automatic updates If you’re still concerned that Microsoft could install updates or even upgrade to Windows 11 on your PC without your permission, there are certain precautions you can take: Disable automatic Windows updates so that only you can decide if and when they’re installed. However, if you do this, you shouldn’t delay critical security updates for too long. Disable TPM so that your PC is no longer eligible for the upgrade to Windows 11. To do this, go to “Security” or “Advanced” in your BIOS settings and search for TPM/FTPM/PTT. (Disabling this should not cause any problems on a Windows 10 PC.) With tools such as Rufus , you can not only install and launch different versions of Windows from a USB flash drive, but also bypass Microsoft’s frequent (annoying) upgrade prompts.
