Windows 10 KB5001649 update is now trying to make its way to version 20H2/2004 machines, but it apparently fails to install with 0x80070541 error code. This optional “emergency” update was issued earlier today to address Blue Screen of Death and other problems reported by users.

But what’s more interesting is that KB5001649 fails to install with 0x80070541. The installation error “0x80070541” is likely due to compatibility issues with Windows 10 March 2021 updates, which were released on March 9.

“We couldn’t install this update, but you can try again (0x80070541). 2021-03 Cumulative Update for Windows 10 Version 20H2 for x64-based Systems (KB5001649),” the error message reads, as shown in the screenshot below:
