FAQ

Should you run fix start menu not opening on windows immediately?

Usually only after you confirm the symptom matches. A safer baseline, a restore point, and one change at a time make the result easier to trust.

What should you verify after running the script?

Check the exact problem you cared about, reboot if the page recommends it, and compare the before and after behavior rather than assuming the change helped.

Can you undo the change later?

For most pages here, yes. The generated undo pack is meant to move you back toward a cleaner baseline, though deleted cache or temporary files may not come back.

Will this page fix every version of the problem?

No. These pages are meant to be high-signal starting points. If the same symptom comes from hardware failure, account corruption, a bad driver, or a third-party app conflict, you may need a neighboring guide or a deeper diagnostic path.
