Security News > 2020 > October > Microsoft removed another Windows 10 2004 safeguard hold

Microsoft removed a Windows 10, version 2004 compatibility hold blocking devices with certain WWAN LTE modems from upgrading to the latest Windows version.
A fix for the issue was made available with the release of the Windows 10 2004 KB4577063 non-security preview cumulative update.
The compatibility hold applied to prevent affected computers from upgrading to Windows 10 2004 was removed on October 15 as Microsoft said in an update made to the Windows 10 health dashboard two days later.
You can still force upgrade your device to Windows 10 2004 using the Media Creation Tool, the Windows 10 Upgrade Assistant, or a Windows 10 2004 ISO for a clean install even if it's impacted by one of the update blocks listed above.
Microsoft advises customers not to manually update if the May 2020 Update is blocked to avoid experiencing issues that might potentially make their Windows 10 devices unusable.
