Hi @Сергей Колыбин ,
I would try and run the simplified patching (one-click-installer) for Update Rollup 2 and run it on your SCOM management server, it will update the management server role, update the databases with SQL scripts, and then import any Management Pack updates.
I would not recommend updating via Windows Update, as there has been many issues by doing that.
