[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.

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).

[German]As of October 10, 2023, Microsoft has released security updates for Exchange Server 2016 and Exchange Server 2019. On a number of Exchange Server systems, the installation of the October 2023 updates ends with error 0x80070534. The cause seems to be the lack of cleanup of the August 2023 update mess.

[German]There is a vulnerability in the library and tool curl in older versions, which was closed by the project on October 11, 2023 with version 8.4.0.

My status is that Windows still includes the outdated curl version after the October 2023 updates.
