What is fhcleanup.dll?

fhcleanup.dll is a legitimate Microsoft system file known as the File History Cleanup COM Server. It is an essential component of the Windows operating system, specifically used by the File History backup feature to clean up old versions of backed-up files and manage storage space.

Standard File Location

The standard and safe location for this file is in the Windows system directory:

C:\Windows\System32\

Note: If you find this file in any other folder (especially temporary folders or the user profile), it could potentially be malware camouflaged as a system file.

How to Fix fhcleanup.dll Errors (Without Downloading Anything)

You do not need to download third-party DLL files, which are often unsafe. Because fhcleanup.dll is an official Windows component, you can repair it using built-in Windows tools.

1. Run the System File Checker (SFC)

This tool scans all protected system files and automatically replaces corrupted or missing ones with a healthy cached copy.

Press the Windows Key, type cmd, right-click Command Prompt, and select Run as administrator.
Type the following command and press Enter:
```
sfc /scannow
```
Wait for the scan to reach 100%. Restart your computer.

2. Run the DISM Tool

If the SFC tool cannot fix the file, the Deployment Image Servicing and Management (DISM) tool will fetch a fresh copy of the file directly from official Windows Update servers.

Open Command Prompt as administrator again.

Type the following command and press Enter:

DISM /Online /Cleanup-Image /RestoreHealth

Allow the process to complete, then restart your PC and run sfc /scannow one more time.

3. Re-register the DLL file

If the file exists but Windows cannot read it correctly, registering the file again via the Command Prompt can resolve the issue.

Open Command Prompt as administrator.
Type the following command and press Enter:
```
regsvr32 /u fhcleanup.dll
```
(This unregisters the file)
Next, type this command and press Enter:
```
regsvr32 fhcleanup.dll
```
(This re-registers the file)
Restart your system.

4. Turn File History Off and On

Since the error is directly tied to the File History backup system, resetting the service can stop the error loop.

Open the Start Menu, type Control Panel, and open it.
Click on Save backup copies of your files with File History (or search for "File History" inside Control Panel).
Click the Turn off button.
Reboot your computer, return to the same menu, and click Turn on.

If the error continues to pop up, let me know:

The exact error message text you are seeing
When the error occurs (e.g., at startup, when opening a specific app, or during a backup)

I can give you a more specific solution based on those details.
