Microsoft has removed a compatibility hold blocking Windows 11 upgrades for Windows 10 customers after fixing a known issue leading to problems importing Internet Explorer 11 data into Microsoft Edge.
The only customers impacted by the now-fixed known issue were those who didn't import their IE11 information into Microsoft Edge before starting the Windows 11 upgrade process.
"This issue was resolved in Microsoft Edge 99.0 for devices upgrading to Windows 11 and devices that have already upgraded to Windows 11," Microsoft explained on the Windows Health dashboard.
According to Microsoft, it can take up to 48 hours before the Windows 11, version 21H2 update is offered on systems where the upgrade block was applied.
After Internet Explorer's retirement, Microsoft will continue supporting legacy Internet Explorer-based websites and apps within Microsoft Edge through the built-in Internet Explorer mode feature.
Once retired on June 15, 2022, the Internet Explorer desktop app will be disabled and automatically redirect to the Microsoft Edge web browser.
