The latest cumulative update for Windows 10 is hiding the data and profiles of some users

27 mayo, 2021

As is customary every Tuesday (patch tuesday), Microsoft launches its common patches for Windows 10 in the form of cumulative updates that are supposed to come to solve problems and fix security flaws. However, as has happened countless times already: they have ended up causing others.

The most recent comes from the update KB4532693 for Windows 10 version 1903 and 1909, that is, the updates for May and November 2019 respectively. Various users on the Microsoft forums, AskWoody, Twitter, and other websites, have been reporting having lost their profiles after installing the patch.

WINDOWS 10: 9 VERY USEFUL and LITTLE KNOWN TRICKS

Missing desktop background, icons, and files

Windows 10 Desktop

Most users say that after installing the update your normal user profiles do not loadTherefore, the desktop configuration, the files present there, the status of the start menu, and the desktop background are shown with the default configuration of Windows 10.

Apparently the problem happens because of a bug in KB4532693 that loads a temporary user profile during the update process, but fails to restore the user’s profile when it finishes.

If you are affected by this problem, the good news is that your data has not been erased (something that did happen with the unfortunate update of October 2018), but they have gone to another user folder with a different name.

Some solutions

Windows 10 Users

The recommendation of some affected is to look in the users folder, that is, C: Users, and see if instead of the folder with your username you get a renamed one that ends in .000 or .bak.

One solution reported by the community is restore user profile from Registry editor, something that probably not many people want or know how to do.

However, uninstall KB4532693 or restart windows multiple times (up to four according to the moderators of the Microsoft answer forum) also seems to have helped some.

Another recommendation is to navigate to C: Users and look through the user folders to see if your files are there somewhere, in case you find them, create a new user profile with administrator privileges, log in with it and copy all your data from that profile to this new one.

If you can’t find your files this way, look in the folder Windows.old on your C drive and check the folders inside to see if they are there. If you get them copy them as soon as possible to a new folder, or they will be erased over time.

Microsoft has not yet acknowledged the existence of this bug.
