The update broke Windows 7. Microsoft has released a partial patch
Bad tradition to break something that works, it seems, has become a trend for Microsoft. And no, this time the problem is not Windows 10 and Windows 7, which many considered to be the best OS from Redmond. As it turned out, a monthly security update brought a whole heap of problems. Although, according to the description, it had to increase defense. In particular, the local users are members of the local Administrators group, there is a problem with remote access on computers running Windows
At the moment, the problem is kind of solved. Microsoft has released an update KB4487345, which solves some bugs, but not all. It is important that the package KB4487345 is not available in automatic mode. You need to download and install it manually.
In the beginning of last week the developers have released a security fix KB4480960 and KB4480970 for Windows 7 SP1 and Windows Server 2008 R2 SP1, respectively, which resulted in many failures. Users have reported error KMS Activation error, and Not Genuine 0xc004f200. It turned out that the problem lies in the old patch KB971033, which for some reason conflicts with KB4480960 and KB4480970. It was not intended for installation in environment a key management service (KMS), but still no problems.
To solve the problem is to remove the problematic update KB971033, clear cache and delete KMS from PC activation data, and then re-activate your system via KMS. Another option is the solution to just not install updates KB4480960 and KB4480970.
It is hoped that in Redmond will take note of these problems and will try to avoid this in the future.
