The undeletable cache issue stems from the «checkpoint update» system, a feature designed to download smaller, incremental patches instead of full updates.
The recent Windows 11 24H2 update is reportedly flawed with a new issue where it creates 8.63GB of undeletable update cache. This cache is made during the update process and seems to remain on the system, despite attempts to remove it using traditional methods like Disk Cleanup, Storage Sense, or even manually deleting system folders like Windows.old .
The issue appears to be linked to checkpoint updates, a new feature in Windows 11 designed to streamline and shrink update sizes by downloading smaller patches rather than full updates.
