    After running WU to get to Microsoft Windows [Version 10.0.18363.836], the enforced restart was not sufficient to get the Windows chirp on keyboard chicklet depression. A shutdown and logon fixed that problem for me.

    It’s really sickening that we have to go through all the anxiety of bricking our machines in a company to ensure security. If MS gave a damn about security they would not update using a system that has been broken since Windows 8 years ago.

    And we get no choice in the matter.

    Really, f*uck Microsoft already. Anyone else agree that this is hopelessly broken and unconscionable?

    And no, not Yuliya.
