Microsoft have already withdrawn it Windows 10 October 2018 Update (version 1809), but the errorthey keep showing up. For example, there have just been reports of disabling the operating system.
Ναι μετά την εγκατάσταση του Windows 10 October 2018 Update (έκδοση 1809) σε υπολογιστές που το λειτουργικό system was already on, the Windows watermark appeared on the surface work. The watermark only appears on non-activated Windows. 
Of course the event brings too many problems for users of the operating system they no longer have key product for their system. Another problem is that they can't find their key with some third party application because their system is not activated.
The only solution is to go back to the previous version of Windows 10, using the "roll-back" function and then find the product key to reinstall the Windows 10 October 2018 Update.
