Last active October 24, 2025 14:12

Aggressively reclaim disk space in a Windows partition

	::
	:: Reclaims Windows disk space in a "destructive" manner (can't uninstall service packs and updates afterwards, etc.).
	:: Use at your own risk. Useful for Windows installations in space-constrained environments, such as a small Boot Camp
	:: partition on a Mac.
	::
	:: [IMPORTANT] It is strongly suggested to make a full-disk backup of your Windows partition before running this script,
	:: as you can't roll back service packs and updates afterwards.
	::
	:: [IMPORTANT] Run this script as admin (required to run `Dism.exe` among other things).
