The order never changes. While Rain Cleaner is checking, nothing is modified.
It only looks at the places it cleans. It does not go through your documents, and it changes nothing while it looks.
For every finding it says what it is, where it came from and what you lose. When something is better left alone, it says so plainly.
You approve the change. With every new driver the old one is kept, so there is always a way back.
Most features wait for your confirmation. Ransomware protection is the exception, because during an active attack a delay means lost files. At the first serious sign it takes a disk snapshot and stops the program that is writing, then shows you what it caught and why. Both actions can be switched off — they are the only ones that happen without asking.
From Microsoft's own update catalogue. Rain Cleaner does not host drivers and does not repackage them. When a manufacturer releases a newer version before Microsoft, it points you at their page.
The old driver is kept before the new one goes in. Rolling back is one click, and it works even when the new driver has broken the network.
No. The changes apply only while the booster is on. If the power goes out mid-game, the next start finds the record and puts the settings back.
For driver updates, yes. Emergency drivers exist for exactly the case where you have no connection.
No, and it is not sold as one. There is no virus database behind it. It watches what a program does — whether it rewrites files, deletes restore points, shuts down the security service.
It does not act on a guess. An odd command can raise an alarm but never stops anything. A program is stopped only on a clear action, and the reason is recorded alongside it.
The connection itself, no. It can measure which DNS servers answer fastest and switch to a faster one, which shortens the pause when you open a new site.
Windows 10, Windows 11 and Windows Server. On a server it advises instead of cleaning.
Rain Cleaner is code-signed by Where2Go LTD, so Windows shows who published it. The signature is new, so SmartScreen may still warn until the file is widely downloaded. If you would rather skip that screen, take the portable version.
