[German]Something is happening: Microsoft has removed a showstopper on July 24, 2025, which had already been set on September 30, 2024, long before the launch of Windows 11 24H2. It concerns Easy Anti-Cheat, a technology used in games, which previously prevented an upgrade to Windows 11 24H2.
[German]The extent of the observed wave of attacks on 0-day vulnerabilities in Microsoft SharePoint is slowly becoming apparent. Microsoft has now released emergency updates for SharePoint Server.

[German]A short addendum that may be of interest to administrators of Microsoft Exchange Server 2016/2019 and Microsoft Skye for Business 2015 and 2019. These software versions were actually due to be removed from support on October 14, 2025.

[German]An addendum to the 0-day vulnerability in Microsoft SharePoint and the observed wave of attacks. Microsoft has also released an emergency update for SharePoint Server 2016. In the meantime, there are reports that some of the attacks came from China via a 0-day exploit.

Here is a review with a summary.
[German]Since Windows 10 22H2 will no longer be supported as of October 14, 2025, we can expect more Windows 11 upgrade campaigns from Microsoft.
