Earlier this week, we reported on a bug discovered by users after upgrading their PCs to Windows 1124H2. When users tried to delete 8.63GB of upgrade data from their systems, they found that it seemed impossible to delete it. Even after scanning and deleting files, the Windows native disk cleaning utility continued to report approximately 8.63GB of data.
There was some speculation that this could be due to the new checkpoint update system, but Microsoft has confirmed that this is not the case. The company said this was a reported issue on Windows 1124H2, and the information reported by the app was inaccurate because the files had indeed been deleted as intended by the user.
The company explained:
After using the Windows Disk Cleanup application, it may show an incorrect amount of freeable disk space in the "Windows Update Cleanup" category.
Please note that this is a reported bug. When you select "Windows Update Cleanup" and run "Disk Cleanup" for the first time, some or all files in this category (for example, 15GB) will be cleaned correctly and the related disk space will be released as expected. However, after the first run, the tool may inaccurately report that there is still a certain amount of space left to clean (e.g., 88GB) in the "Windows Update Cleanup" category. This inaccurate amount of disk space is reported even though the disk space has been freed during the initial run.
The company said it is investigating the root cause of the issue and will provide a solution once it is fixed. You can find the issue on the official Windows Health Dashboard website here.
If you're wondering about other Windows 1124H2 issues, this month's Windows 11 Patch Tuesday update fixes bugs that cause boot loops and Bluetooth/USB connection failures. Now also available through the official media creation tool.
The tech giant also promised that a fix for the SFC scanning bug will be coming soon. However, some quirks have not yet been resolved, such as a BSOD issue on WDHMB-based NVMe SSDs that requires registry tricks to fix.
