The ultimate optimizer for Windows
Maximum speed. Zero bloatware.
Clean gigabytes of leftover Windows files, stop invasive telemetry, speed up your boot time and unclog your PC's performance in a single click.
⚠️ Some antivirus tools may flag the installer on first run. This is a known false positive with unsigned Python-based Windows apps that request admin access — not a sign of anything malicious. Read why, and how to verify the file yourself.

Why You Can Trust This
No fake reviews, no countdown timers, no "expiring" discounts. Just what's actually true.
SHA-256 verified installer
Every download is checked against a cryptographic hash before it runs. If the file doesn't match exactly, the app refuses to install it — no unverified binaries, ever.
No telemetry added by us
We don't add our own analytics or tracking. What Windows itself collects is a separate matter — and that's exactly what the Telemetry Blocker module is for.
14-day refund, no questions
Email us within 14 days of buying and you get a full refund. No form to fill in, no reason required — it's in our published refund policy, not just a sales claim.
One developer, not a faceless company
OpenClean Studio Pro is an independent project. Support emails go straight to the person who wrote the code — not a ticket queue.
One price, no dark patterns
€8.99 + VAT, once. No subscription, no auto-renewal, no surprise charge on your card next month.
Newly launched — try before you buy
This product is new, so we'd rather say that plainly than fake years of five-star reviews. Download the free demo and judge it on your own PC first.
Frequently Asked Questions
Everything you need to know about licensing, payments and compatibility.
We've reported these false positives to the antivirus vendors, and we're working on getting the installer code-signed, which resolves most of these warnings. In the meantime, you can verify the file yourself: check its SHA-256 checksum, or scan it on VirusTotal before running it.
