[German]Microsoft has released the cumulative update KB4535996 in the Insider Preview Release Preview Ring for Windows 10 V190x on February 26, 2020. Addendum: The update has been released to all users, see Windows 10 Version 190x: Update KB4535996 (Feb. 27, 2020).
The update is available for Windows 10 version 1903 and version 1909. The update raises the builds 18362/18363 to the subbuild .693.
What exactly has been changed is unclear. But it’s not a security update – you may be tampering with the problem of broken user profiles (see Windows 10: Update KB4532693 kills user data/profile). Possibly it will be generally released tonight (2/27/202020). via
