In my experience, at various points in the lifetime of a Windows install, it's not uncommon to find Microsoft's OS leaving chunky update files behind that you have to manually clean up yourself. More than once I've wondered where an extra 5 GB or so of my SSD space has gone, only to realise that Windows hasn't been tidying up after itself the way I would hope.
Still, it's normally a matter of running the Disk Cleanup utility, tutting appropriately at the leftover update files as they're removed, and wagging your finger at your machine before you go to bed. Some users of the new Windows 11 24H2 update, however, have been left with a chonky 8.63 GB update cache that simply refuses to be deleted (via Windows Latest).
