What you need to know

  • After updating to the Windows 11 2024 Update, PCs are showing an 8.63GB set of files that cannot be deleted.
  • Major Windows 11 upgrades usually leave a large chunk of files on a system, but you have the option to delete those files.
  • Several people have reported the storage bug after installing the Windows 11 2024 Update, and we have been able to replicate it on several PCs.

Microsoft rolled out the Windows 11 2024 Update recently, bringing new features and performance improvements to PCs. Unfortunately, the update also brings a bug that effectively steals 8.63GB of storage on your system. Following the update, PCs will show 8.63GB of files in the "Windows Update Cleanup" section of Temporary files. While Windows presents an option to delete the files, electing to do so fails to clear a PC's storage.

After updating to a new version of Windows 11, it's normal to see a sizeable group of files, but Windows gives you the option to delete those files. That does not appear to be the case after the Windows 11 2024 Update.

Some debate if the 8.63GB of files stuck on systems is due to a bug or not. Windows has allowed you to delete these types of files for years, so it seems unlikely that would change. Even if there was a change to Windows 11 that resulted in those files having to stay in place, it would be an issue to show them in Storage Sense. Having Storage Sense show 8.63GB of files that can be deleted only to not be able to delete those files is a poor user experience.

The storage issue has been flagged up several times across the web, including by Eleven Forum members and people on the My Digital Life forum. Windows Latest covered the phenomenon, and we have been able to replicate the issue on several PCs as well.

    Normally Windows 11 will delete the windows.old folder after 10 days. That is what it did when after I installed 24H2 in September.

    No leftover undeletable files here after a 24H2 clean install. I also ran CleanMgr+ just to be sure and it too didn't show leftover files.
    Aah, now I recall: I used an ISO created at UUPDUMP (which uses Microsoft Update Servers to assemble install packages) and selected "Run Component Cleanup" as part of the process. Maybe that's why . . .

    (Apologies, the forum won't allow me to post the links. Just search.)
