Hi,
After installing the driver you recommended, there was a restart, but the error persisted. Then I realized that several repositories were missing, as you indicated. I resolved it as follows: I compared the folder on this server with another server that was updating correctly, and I imported all the missing folders within System32/DriverStore/FileRepository. After that, the update worked correctly, and now the server is 100%. Thank you so much, Maxstar, for all your support!
