Microsoft is blocking the upgrade from Windows 10 to Windows 11 for users who use Internet Explorer 11 as their default browser. This temporary measure should avoid data loss. Users who want to upgrade must first import their IE11 data into Edge browser.
Microsoft has taken this action In their own words Because the data saved in Internet Explorer 11, after upgrading from Windows 10 to Windows 11, will no longer be accessible due to an error some users have. To avoid this data loss, the system now checks before starting the upgrade to Windows 11 (version 21H2) if data has already been imported from Internet Explorer 11 to Edge browser. It is not clear what data is included.
The company offers this procedure only to Windows 10 users who use Internet Explorer 11 as their default browser, or who, according to the company, frequently use that browser. It’s not clear what parameters Microsoft uses to measure this. The company will block the upgrade to Windows 11 for these users and will block notifications for the switch for the time being. Windows 10 users who have imported data from IE11 to Edge browser will be able to update to Windows 11.
The company says it is working on a solution to the problem. This fix will be added in a future version of the Edge browser. However, it is not clear when it will be released.
