The Windows 11 24H2 update continues to roll out at a good pace. The new and only major version for 2024 is the basis of the operating system without revolutionizing it, but at least it modified the functions that were necessary and opened the era of artificial intelligence functions for certain tasks on the PC. is it perfect Well, no, in any sense.

And Windows updates haven’t exactly been great with their stability. On the contrary, caused a number of problems. The new version is not exempt from them and some have already been registered in different sections. It is not clear whether what we are discussing in this article is a bug or the result of changes in the update system.

Since Microsoft updated the latest feature update, several users have reported that they are unable to perform a Windows Update cleanup that will allow users to free up space. So apparently all users who update to Windows 11 24H2 will find out cannot continue deleting 8.63 GB of previous cumulative updateswhich was possible in previous versions of the operating system.

Cleanup also doesn’t work with Disk Cleanup. If it runs, it still shows an item called “Windows Update Cleanup” with the mentioned 8.63 GB. Disk Cleanup will not remove it.

There are doubts whether this is a bug or something motivated by some change planned by Microsoft and specifically referring to a new way to deliver Windows cumulative updates which Microsoft introduced with Windows 11 24H2 and Server 2025. Called “cumulative checkpoint updates” (CCUs), the company essentially delivered them as checkpoints instead of a full update from RTM, reducing the size of each update. That might be why the stubborn 8.63GB can’t be deleted.

On most modern personal computers It shouldn’t be a problem. On desktops we have a “terrace” of capacities, while on laptops the average has also increased and most have at least one SSD with 512 Gbytes.
