There are many complaints on the Internet that in Windows 10, after the 2004 update, applications lose cookies. The problem is that after the update DPAPI somehow does not work properly. Unfortunately, the data cannot be restored, but it is possible to make browsers work without entering passwords at every reboot, and not to roll back from 2004. Under the cut - the method that worked for me.
Making a local administrator
We make Logout from the current user and go under the administrator
Go to% userprofile% \ AppData \ Roaming \ Microsoft of the user where you need to restore DPAPI
transfer directories somewhere: Crypto and Protect
log in as the old user and turn on sync again in browser profiles, Microsoft store, and Microsoft applications - in general, everywhere where DPAPI was used
