Windows 10 sometimes automatically runs certain troubleshooters for some devices. For instance, Microsoft has recently released troubleshooter for select devices to fix the OneDrive’s Files on-demand issue.
Similarly, Microsoft has also released Disk Cleanup Troubleshooter for Windows 10 devices running 19041.21 to temporarily disable “the automatic running of Disk Cleanup until devices install the Windows version 19041.84 update”.
Microsoft’s support page claims “this troubleshooter automatically runs twice. It runs for the first time on all Windows version 19041.21. It then runs again after devices upgraded to Windows version 19041.84”.
