Windows Maintenance

Rebuild Icon Cache

Open a command prompt:

TaskKill /f /im explorer.exe
DEL /F "%LocalAppData%\Microsoft\Windows\Explorer\*Cache*.db"
DEL /F "%LocalAppData%\IconCache.db"
explorer.exe

Alternatively:

ie4uinit.exe -show

Freeing Space

You can compact / free up WSL virtual hdd with the following:

wsl --manage docker-desktop

docker image prune -a # Prune all images that aren't in use by any containers
docker container prune
docker volume prune

Deployment Image Servicing and Management tool (DISM)

DISM can be used to mount and service a Windows image from a .wim file, .vhd file, or a .vhdx file or, in some cases, to update a running operating system.

You can use DISM to do various cleanup operations related to installed components, updates and service packs.

Remove Service Pack backup components after Service Pack installation

After installing a Service Pack, you can clean up backed up components:

dism /online /cleanup-image /spsuperseded /hidesp

Note this will make it impossible to uninstall the service pack.

Remove all superceded components

dism /online /Cleanup-Image /StartComponentCleanup /ResetBase

This will clean up updates and service pack components, but mean you cannot uninstall Service Packs or installed Windows Updates.
