[German]Exchange Online administrators may have received a number of copies of their users' outgoing emails classified as spam in the last few hours. The cause was a spam rule causing false-positive spam notifications. Microsoft has confirmed the whole thing as Incident EX682041 and initiated countermeasures (disabling the rule). The problem should be solved with this.

[German]Microsoft wants to get rid of some of its Windows users. That's how I interpret the fact that Microsoft published instructions on how to install Linux on their systems at the end of September 2023. Coincides with the terminated upgrade to Windows 10/11 via Windows 7/8.1 product key.

Uninstalling the affected updates fixes these problems again.
[German]I'm going to address an old issue that might affect administrators who are migrating clients to Windows 11. In some scenarios, applications run very slowly or the system or applications start sluggishly. The clients are underperforming, even if the application was sufficient for Windows 10. One reason could be that the applications or their network connections are slowed down by Microsoft Defender. In the meantime, however, it is the case that Microsoft Defender cannot be disabled under Windows 11 (now also under Windows 10) via policies or a registry entry. Only when using third-party antivirus solutions can Microsoft Defender be deactivated and put into passive mode.
[German]After releasing the October 2023 updates, Windows Server 2012 and Windows Server 2012 R2 have reached their end of support; there will be no more security updates in the future – unless customers buys an Extended Security Update extension (ESU license). Now an info from a reader reaches me that these ESU licenses are not provided for on-premises systems. But there is an alternative in the form of 0patch micro patches.
[German]Quick warning for readers who are on the Steam platform. A reader has alerted me to a wave of scams that is currently running and operates with fake accounts.
