Microsoft has added a new safeguard hold blocking Windows 11 upgrades for Windows 10 customers who don't import their Internet Explorer 11 (IE11) data into Microsoft Edge before trying to install the newest Windows version.
"After upgrading to Windows 11, saved information and data from Internet Explorer 11 (IE11) might not be accessible if you did not accept to import it into Microsoft Edge before the upgrade," Microsoft explained in the Windows health dashboard.
"To safeguard your upgrade experience, we have applied a compatibility hold on devices affected by this issue to prevent them from installing or being offered Windows 11."
The new compatibility hold affects only Windows 10 systems where IE11 is the main web browser or is set as the default browser.
Starting today, it will automatically block impacted Windows devices from being offered or installing Windows 11.
This new safeguard hold should not affect customers who have already imported their IE11 information into Microsoft Edge before hitting the Windows 11 upgrade button.
Fix coming via Microsoft Edge update
Redmond says it's currently working on a fix for this known issue, delivered with a future Microsoft Edge update.
"The issue should be resolved for devices that have not yet upgraded and devices that have already upgraded to Windows 11 without accepting to import IE11 data into Edge," Microsoft added.
Before applying this safeguard hold, Microsoft removed four other upgrade blocks, the last one in March:
IE11 desktop app will be retired in June
In March, Microsoft has reminded Windows customers that Internet Explorer 11 will finally be retired from some Windows 10 versions in June to be replaced with the new Chromium-based Microsoft Edge.
After retiring Internet Explorer, Microsoft will still provide support for legacy Internet Explorer-based websites and apps within Microsoft Edge via the built-in Internet Explorer mode (IE mode) feature.
Once retired on June 15, 2022, the Internet Explorer desktop app will be disabled and it will automatically redirect the users to Microsoft Edge.
