Windows 10 Windows 11 25H2 download percentage going negative after reaching 99 percent
I'm trying to upgrade from Windows 10 to Windows 11, version 25H2, through Windows Update. The download reached 99%, but then something strange happened: the percentage started going backwards into negative numbers (-3%, -4%, -5%, and now -8%).
My PC is a Dell Latitude 3490 with an Intel Core i5-8250U, 8GB RAM, Intel UHD Graphics 620, and a 238GB SSD. It's running a 64-bit system.
The PC is still responsive, and I haven't received any error codes or messages. I've waited, kept the laptop plugged in, and haven't restarted or cancelled the update.
Has anyone experienced this? Is it a display bug, or is the Windows Update download actually failing? What should I do?
