The fix applies to Windows 10 and Windows 11 (including 25H2) systems.
No reboot should be necessary after running the fix. If you get the following error, you may ignore it because some of the above keys may already exist.
Cannot import drive_properties_fix.reg: Not all data was successfully written to the registry. Some keys are open by the system or other processes, or you have insufficient privileges to perform this operation.
Note: If the issue is unresolved, please launch regedit.exe under the TrustedInstaller privileges and import the registry file manually via the File menu. For more information, please see the article How to Run Programs as TrustedInstaller to Write to Certain Registry Keys or Files.
That should resolve the issue.
