The 2004 version of Windows 10, or the May 2020 Update was released a few months ago and continues to be available on more devices as Microsoft uses a step-by-step debugging feature.
When a problem is detected, the availability of subsets of devices that could be affected by the same issue is automatically suspended, and Microsoft promises updates.
However, Microsoft seems to have fixed it recently some issues without the need to upgrade. One such example is a recent problem with the Disk Cleanup tool, which Microsoft says crashed some devices to the point where they could not boot.
Microsoft doesn't say much about the whole thing, though confirms THE EXCELLENT:
"Some devices may fail to boot if Disk Cleanup runs after you install the Windows Update 19041.21."
Thus technically, after installing the Windows 10 May 2020 Update on build 19041.21, Disk Cleanup can cause damage to the boot of the device. Disk Cleanup may remove some critical system files, but we do not yet have any official confirmation from Microsoft.
To resolve the issue, Microsoft offers a special Disk Cleanup Troubleshooter that is enabled on Windows 10 devices and starts automatically. What this troubleshooting tool does is simply disable the automatic launch of the Disk Cleanup application, possibly to prevent the removal of some files that are needed.
"The troubleshooter temporarily disables the automatic execution of Disk Cleanup until the devices install the Windows 19041.84 update," says Microsoft.
The troubleshooting tool cannot be started manually and will only run automatically if the aforementioned problem affects your device.
