Verify your download
Open PowerShell in the folder where you saved the installer and run:
Get-FileHash .\RainCleaner-Setup-2.22.0.msi -Algorithm SHA256The result must match the SHA-256 above, character for character. If it does not, do not run the file.
Digital signature
Right-click the file → Properties → Digital Signatures. The signer must be Where2Go LTD and the signature must be valid. If the tab is missing or shows another name, do not run the file.
Signs of a file that is not ours
- The SHA-256 does not match the one on this page.
- It came as an .exe wrapper, a download manager or a “setup” with offers — ours is a plain .msi or .zip.
- Someone asks you to pay outside the program or outside Stripe checkout.
- It came from a site that is not in the official sources list below.

What Rain Cleaner can change
This is every area where the program can change something on your PC. Nothing happens until you press the button for it.
| Area | What it reads | What it may change | Asks first | Can be undone | Record kept |
|---|---|---|---|---|---|
| Cleanup | Sizes of temp folders, Windows Update download cache, Delivery Optimization, setup logs, crash dumps, thumbnail and browser caches, Windows.old, Recycle Bin | Deletes files inside those folders only. A fixed list of allowed folders is enforced right before every delete. | Yes — you pick the items | No. Deleted cache files are gone (Windows and browsers rebuild them). | History entry with every group and its size |
| Startup programs | The same startup lists Task Manager shows | Switches an entry off or on the way Task Manager does, with the approval flag. Nothing is deleted. | Yes | Yes — switch it back here or in Task Manager | History entry |
| Drivers | Installed drivers and what Windows Update offers for your hardware | Installs drivers from Microsoft’s Windows Update catalogue only. Makes a restore point and exports the current drivers first; if neither works, nothing is installed. | Yes | Yes — roll back to the restore point or the exported drivers | History entry, driver backup folder |
| DNS | Your current DNS server and the response times of Cloudflare, Google, Quad9, OpenDNS and AdGuard | Switches the network adapter to the DNS server you choose. | Yes | Yes — the previous DNS is kept and can be restored | History entry with before and after |
| Game Booster | Running processes and the power plan | For the session only: game priority up, a short list of background programs eased off, High performance power plan, GPU preference for the game. | Yes — you press Boost | Yes — ends with the session, and is restored on the next start after a crash or power cut | Session file on disk + history |
| Offline rescue | Network devices without a working driver | Reinstalls network drivers already on the PC, through Microsoft’s pnputil, when there is no internet. | Yes | Partly — drivers are exported before changes | History entry |
| Ransomware shield | Hidden bait files in your user folders and who writes to them | On signs of encryption it can take a shadow copy and, if you allowed it, stop the process that is doing the writing. It never deletes a file on its own. | You decide whether it may stop processes and take snapshots | Yes — files can be rolled back from the shadow copy | Hash-chained shield journal |
| Programs | The installed programs list Windows keeps | Starts a program’s own uninstaller. Rain Cleaner never deletes program files itself. | Yes | No — reinstall the program | History entry |
| Pro: Autopilot and space agent | Disk space and the same cleanup groups | Runs the safe cleanup on a schedule you turn on. Finds drivers but never installs them without you. | You turn it on once; nothing risky runs on its own | As for Cleanup | History entry for every run |
What Rain Cleaner will never do
- Clean the registry. There is no registry cleaner and there will not be one.
- Show a “free RAM” button. The booster eases off background programs during a game; it makes no memory-cleaner claims.
- Promise “300% faster” or any number it did not measure on your PC.
- Bundle other software, toolbars or offers.
- Install drivers from anywhere but Microsoft’s catalogue.
- Touch Documents, Desktop, Pictures, Videos, Music, Downloads or any personal file.
- Mine crypto, sell data or share what is on your PC.
- Invent threats or inflate numbers to scare you into buying.
- Do something risky without asking you first.
What happens when you click Clean
- 1Scan
Measures each folder. Nothing is changed.
- 2Explain
Shows what each group is and why it is safe.
- 3You approve
You choose what goes. Nothing is pre-ticked that should not be.
- 4Safety net
For drivers: a restore point and a driver export first.
- 5Action
Deletes only inside the allowed folders, checked file by file.
- 6History
Writes what was done, before and after, to the action history.
The history lives in ProgramData\RainCleaner\history, one file per month, readable only by administrators. You can export it; names, paths and identifiers are removed from the export.
Privacy and network
Rain Cleaner has no in-app telemetry or third-party analytics; server logs are only aggregated into daily statistics. Your scans, history and settings stay on your PC. These are all the servers it contacts:
| Server | Why | What is sent | Required |
|---|---|---|---|
raincleaner.eu/v1/version | Update check, at most once a day | Nothing but the request itself | Can be turned off in Settings |
raincleaner.eu/v1/activate, /trial, /release, /portal | Pro licence | Your licence key and a machine ID (a SHA-256 hash, see below) | Only for Pro |
Windows Update (Microsoft) | Finding and downloading drivers | What Windows sends to Windows Update | Only when you search for drivers |
1.1.1.1, 8.8.8.8, 9.9.9.9, 208.67.222.222, 94.140.14.14 | DNS speed test | Five lookups of public names (google.com, microsoft.com…) | Only when you run the network test |
Stripe checkout (in your browser) | Buying Pro | What you type on Stripe’s page; card data never reaches us | Only when you buy |
Machine ID: a SHA-256 hash of the Windows MachineGuid, the system drive size and the PC name, cut to 32 characters. It lets a licence work on the same PC after a reinstall. It cannot be turned back into any of those values.
Never sent
- Files, file names or paths
- Browsing history or passwords
- The list of your programs
- Scan results or your action history
- Anything while Rain Cleaner is not running
Diagnostic data leaves your PC only if you export the history yourself and send it to us.
Recovery and what can be undone
Can be undone
- Drivers — restore point plus an export in ProgramData\RainCleaner\driver-backups
- Startup entries — switch them back on
- DNS — the previous server is recorded
- Game Booster — every change is written before it is made and restored when the session ends
- Files hit by ransomware — from the shadow copy, if the shield made one
- Pro: Undo Anything reverses entries in the history that have an undo step
Cannot be undone
- Deleted temp and cache files
- An emptied Recycle Bin
- A removed Windows.old folder (you can no longer go back to the previous Windows)
- An uninstalled program (reinstall it)
We do not promise that everything can be undone. The list above is what the program actually records.

Questions people ask
Is Rain Cleaner safe to use?
You can check it yourself on this page: the installer and the program files are code-signed by Where2Go LTD, and the current Microsoft Defender and VirusTotal results and the SHA-256 of every file are listed. Nothing is deleted until you approve the list, there is no in-app telemetry, and driver, startup, DNS and Game Booster changes can be undone.
How can I check that my Rain Cleaner download is genuine?
Download it from raincleaner.eu or one of the official sources on this page. Then run Get-FileHash in PowerShell on the file and compare the result with the SHA-256 in the Current release table. If the two values differ, do not run the file.
Is Rain Cleaner code-signed?
Yes. From version 2.15.1 the installer and the program files are signed by Where2Go LTD. To check, right-click the file → Properties → Digital Signatures: the signer must be Where2Go LTD and the signature must be valid. The signature is new, so SmartScreen may still warn for a while.
Does Rain Cleaner send data about my PC?
There is no in-app telemetry and no third-party analytics. Your scans, history and settings stay on your PC. The program contacts our server for the update check (at most once a day, can be turned off) and, with Pro, for licence checks with your key and a hashed machine ID. Every server it talks to is listed under Privacy and network.
Is Rain Cleaner an antivirus?
No. It has no signature database and is not sold as an antivirus. Its ransomware shield watches hidden bait files; on signs of encryption it can take a shadow copy and, if you allowed it, stop the process doing the writing.
Can I undo what Rain Cleaner changed?
Driver installs, startup entries, DNS changes and Game Booster sessions can be undone. Deleted temp and cache files, an emptied Recycle Bin, a removed Windows.old folder and uninstalled programs cannot. Rain Cleaner asks before each of these changes.
