How to Fix Errors Without Downloading

DLL errors usually mean the file is corrupted, misplaced, or deregistered. You can fix this safely using built-in Windows tools.

Method 1: Run System File Checker (SFC)

This tool scans and repairs corrupted Windows system files automatically.

1. Press Windows Key + X.
2. Select Command Prompt (Admin) or Terminal (Admin).
3. Type sfc /scannow and press Enter.
4. Restart your computer after the scan finishes.

Method 2: Run DISM Tool

If SFC fails, the Deployment Image Servicing and Management tool fixes deep system corruption.

1. Open Command Prompt (Admin).
2. Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
3. Wait for the process to hit 100%.
4. Run the sfc /scannow command one more time.

Method 3: Re-register the DLL File

If the file exists but Windows cannot read it, re-registering it fixes the link.

1. Open Command Prompt (Admin).
2. Type regsvr32 /u compiledcomposition.microsoft.powershell.gpowershell.dll to unregister.
3. Type regsvr32 compiledcomposition.microsoft.powershell.gpowershell.dll to re-register.
4. Press Enter and restart.

Method 4: Turn PowerShell Features Off and On

This forces Windows to reinstall clean copies of the PowerShell binaries.

1. Press Windows Key + R, type optionalfeatures, and press Enter.
2. Scroll down to Windows PowerShell.
3. Uncheck the box and click OK (removes the feature).
4. Reboot your computer.
5. Open Optional Features again, check the box, and click OK (reinstalls the feature).
