Damaged Windows filesRuns Microsoft's built-in repair, which finds and restores corrupted system files.
Drive optimizationTidies how files are stored so the drive finds them faster. Windows picks the right method for your drive.
Registry checkSaves a backup to your Desktop first, then looks for leftovers from uninstalled programs. Looks only; changes nothing.
What it never touches
If it's yours, ORION leaves it alone.
Your filesDocuments, photos, videos, downloads, desktop. Nothing in the Recycle Bin either.
Passwords and loginsYou stay signed in to everything. Browser history and bookmarks stay too.
Your programs and settingsNothing gets uninstalled, disabled, or turned off. No Windows services are changed.
Anything that needs a restartIt finishes and you keep working. Restarting afterward is optional.
How to run it
About five minutes. You can keep using the computer while it works.
STEP 1
Download itThe button at the top. Save it anywhere — Downloads is fine.
STEP 2
Right-click → Run as administratorIt needs permission to clean Windows' own folders. Click Yes when Windows asks.
STEP 3
Click Clean & Speed UpThat's the only button. It tells you what it did when it's done.
If Windows shows "Windows protected your PC": click More info, then Run anyway. That warning appears for any small program that isn't from a big company — it's not a virus scan result.
It makes a backup first. Before anything runs, ORION saves a copy of your Windows registry to your Desktop. There's an Undo last run button inside the app if anything feels off.
There's an Advanced area for people who know what they're doing — turning off background services, clearing browser cookies, that kind of thing. The one-click button never touches any of it.
No ads, no account, no internet needed. It doesn't phone home. Run it once and delete it, or keep it around for next time.
