Microsoft’s release of Windows 10 KB4549951 has caused a series of problems for users who have installed the update. To make matters worse, after that, the same patch KB4549951 has brought new problems to many users. Users reported that after the update was installed, Windows 10 replaced their user profile with a new user profile. Worse, it can also make documents, pictures, and other important files disappear.
However, this bug does not permanently delete your data. This isn’t the first time you’ve seen users complain about user profile loss and data being automatically deleted. Many users experienced similar problems after it was updated to Windows 10 in October 2018.
According to Microsoft staff, the easiest way to solve user profile loss is to set up a new profile and manually transfer the data to a new profile that you just created.
For some users, Windows has been restarted more than 6 times, and after the application KB4549951, the missing profile and data loss are back.
Microsoft still hasn’t given an official solution, which means that if the above workarounddoes don’t work on your PC, you don’t have any choice to get back to normal.
And that’s why regular backups of Windows 10 systems are critical, and the high rate of Windows 10 patch rollovers isn’t news, and to make sure you don’t lose important files, W recommends that you back up your Windows PC regularly.
