How to uninstall K-Lite Codec Pack Standard on Windows

Save wanted files and settings before removing K-Lite Codec Pack Standard 20.0.0 on Windows. The locations below were observed in this test; keep shared components separate from app data.

Use the app's uninstaller

Quit the bundled MPC-HC player and configuration tools, then uninstall K-Lite Codec Pack from Settings › Apps › Installed apps.

Data and remaining locations

Enter each complete path in File Explorer. Copy wanted data and settings first; unused caches can be removed. Keep drivers, shared parent folders and shared registrations.

Check the result

Get-Process 'mpc-hc64','CodecTweakTool','mediainfo' -ErrorAction SilentlyContinue
Test-Path "${env:ProgramFiles(x86)}\K-Lite Codec Pack" -ErrorAction Stop
Test-Path 'HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\KLiteCodecPack_is1' -ErrorAction Stop
winget list --id CodecGuide.K-LiteCodecPack.Standard --exact

Test-Path returns True if that exact path exists and False if it is absent; True is expected for data you kept. Resolve query errors before drawing a conclusion. If a process, service or app query lists this product, check its path and installation source. Empty output with suppressed errors alone does not prove removal.

If you installed it with winget

These commands invoke the vendor uninstaller. This test used Mole and did not repeat removal separately through winget.

winget uninstall --id CodecGuide.K-LiteCodecPack.Standard --exact

What Mole lists

The program, Start menu shortcuts for bundled tools and usage records are selected by default. Shared file associations and the Windows graphics-preferences container remain.

What this test covered

Tested on October 5, 2026, in a Windows 11 ARM64 VM with a Mole development build, covering first launch and uninstall. Playback, codec functionality or settings recovery, other installation channels and the released download were not verified. Automatic detection after an external uninstall was not verified.
