This pops up every time i start up pc

Just checked one of my other computers and saw that it was also showing the same popup/date of expiry.

It is on 25324.1001 Windows 11 Pro Insider Preview and that is a way old build that you should get updated!

To update, you will either in-place upgrade with the right edition/language of Windows 11 Insider via link: https://aka.ms/wipiso

Or you will go to Windows Update; make sure that your insider channels are still correct and checking for updates to flight to the next build!
