IE11 data might not be accessible, Microsoft suspends Windows 11 rollout to some users

According to the latest news from Microsoft’s Windows 11 Health Dashboard, due to data compatibility issues with the IE11 browser, Microsoft has decided to suspend the push of Windows 11 systems to some users.
Windows 11 Insider Preview Build 22518
The problem that arises this time is also very simple, if users do not agree to import all data of the IE11 browser into the Microsoft Edge browser before upgrading to Windows 11, they will not be able to access the data saved in the IE11 browser after the upgrade. Why can’t it be accessed? Because Windows 11 does not have the IE browser pre-installed at all, it means that the data is gone.

This issue only affects a small number of users, such as Windows 10 21H2 users who set IE11 as their default browser. Starting today, those users who do not agree to import data will not receive Windows 11 updates from Microsoft, and Microsoft says it is working on a solution. However, it is very simple to solve this problem. Users only need to agree to import data.
