When a problem is detected, the distribution 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 following:
"Some devices may fail to boot if Disk Cleanup runs after you install the Windows Update 19041.21."
So technically, after its installation Windows 10 May 2020 Update to build 19041.21, Disk Cleanup can damage 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 troubleshooting tool for Disk Cleanup that is enabled on devices Windows 10 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 troubleshooting tool 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.
