Facepalm: What's worse than (another) full-screen pop-up from Microsoft warning Windows 10 users that they should be planning for Windows 11's arrival? A pop-up that freezes and crashes as soon as it appears. It's not a good look for Microsoft and does little to instill confidence in Windows 10 users who refuse to upgrade despite the OS' impending end-of-support date. Microsoft has been nagging Windows 10 users to move to Windows 11 for years. With the older operating system reaching its end-of-life date on October 14, 2025, the Redmond firm has been ramping up its efforts to get people to make the move, reviving an aggressive upgrade campaign in February and again in November.Most people still using Windows 10 have little intention of upgrading until they absolutely have to, which means intrusive, full-screen pop-ups aren't something they want to see. Incredibly, Microsoft has managed to make its latest one even worse for some users.As reported by WindowsLatest, Microsoft recently started rolling out a new full-screen pop-up titled "Start planning for Windows 10 end of support." The message contains the usual information about Windows 10 no longer receiving security updates after its end-of-support date, and Windows Backup helping users transfer important files.X user @ems_konto highlighted another issue some Windows 10 users are discovering with the pop-up: it stops responding after it appears, showing a message that reads "Reusable UX Interaction Manager is not working." // Related StoriesThe Reusable UX Interaction Manager (RUXIM) is a component of Windows primarily associated with Windows Update. It assists in scheduling and delivering these updates and managing interaction campaigns, which includes full-screen notifications or messages related to system updates or promotions, such as the Windows 11 campaign.For the first time ever, Microsoft is allowing individual users, not just those in enterprise and education, to continue receiving Critical and Important security updates for Windows 10 after the October 14 end-of-support date. The caveats are that it will cost $30 for a year and new features, bug fixes, and technical support will not be included in the program.Despite Microsoft's efforts, Windows 10's global market share increased over the previous two months to 62.7% while Windows 11 fell to 34.1%, according to Statcounter. The Steam survey paints a different picture, though: Windows 11 is the most popular OS among participants. It holds a 55% share while Windows 10 has dropped to 42%.Will you be moving to Windows 11 this year?
