Problems with Windows scaling after the latest release.
Problems with Windows scaling after the latest release.
It seems the latest update affected my scaling settings severely, making it impossible to use the system again. I had to reinstall Windows. You might want to try DDU to show drivers and reinstall them. If that fails, ensure all monitors are set to 100% scaling, then sign out/reboot and reapply your preferred values. As a last option, consider removing the old DPI registry data (back it up first).
The September update KB5065426 introduced several new bugs, though scaling problems weren’t mentioned. It’s possible the update could cause such issues as well. https://www.windowslatest.com/2025/09/22...25-update/ You can submit your problem to Microsoft via their "Feedback hub" app—its usefulness remains unclear.
It occurred before on my laptop too. The reason wasn’t clear, just a random day. I tried disabling the custom scaling and signing out option, and it fixed the issue.
