How to Fix `windows.storage.compression.dll` Errors Without Downloading

Do not download individual DLL files from third-party websites. Those files are often outdated, bundled with malware, or cryptographically unsigned. Instead, repair the file using native Windows troubleshooting tools.

1. Run the System File Checker (SFC)

The SFC utility scans your core operating system files for corruption and automatically replaces missing or damaged DLLs using a secure local cached copy.

Press the Windows Key.
Type cmd.
Right-click Command Prompt.
Select Run as administrator.
Type sfc /scannow and press Enter.
Wait for the verification process to hit 100%.
Reboot your computer.

2. Run the Deployment Image Servicing and Management (DISM) Tool

If the SFC tool cannot find a clean cached version of the DLL to replace the broken one, use DISM. This utility connects to official Windows Update servers to pull down authentic system components.

Open Command Prompt as an administrator.
Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
Let the tool complete its repairs (this requires an active internet connection).
Restart your computer.

3. Re-register the DLL File

If the file exists physically in your System32 directory but Windows throws registration errors, you can manually reset its registration entry in the Windows Registry.

Open Command Prompt as an administrator.
Type regsvr32 /u windows.storage.compression.dll to unregister the file and press Enter.
Type regsvr32 windows.storage.compression.dll to re-register the file and press Enter.
Close the command prompt and test the application again.
