[German]Microsoft has released two updates for the currently supported Windows 10 versions on March 21, 2023. Once there is the optional Windows 10 preview update KB5023773 (C-Week). In addition, Microsoft has released an OOBE update KB5025801 for Windows 10. Below I summarize the relevant information.
[German]I had already reported on issues with Windows Defender on Microsoft Windows 11. Affected people reported a defender warning "Local Security Authority protection is disabled". However, the LSA protection could not be enabled. The bug has been hit Windows 11 users for several weeks, and Microsoft has now confirmed the issue.
[English]Microsoft has once again announced a change in the update cycle for Windows (10 and 11 as well as Sever). Non-security-relevant preview updates will always be rolled out in the fourth week of a month (D-Week) starting in April 2023. This is according to a Techcommunity article that explains the various updates for Windows.
[German]After the release of the cumulative security updates for Windows 11, reports have surfaced on the Internet that the performance of SSD drives has noticeably decreased following the update installation. Uninstalling the March 14, 2023 security update causes SSDs to return to their original read/write rates. It doesn't seem to be a general problem though, but depends on the SSD models used.

[German]Security researchers from Palo Alto Networks came across a new strain of ransomware at the end of 2022 that is currently still operating "under the radar" of many security researchers.

[German]Windows 111 22H2 users are annoyed since months by a Defender warning "Local Security Authority protection is off". It seems that it correspondents with Windows Defender update KB5007651. Some registry entries allow to remove that warning/malfunction.
[English]In February 2023, I had a poll on the blog regarding connection issues with Microsoft 365 applications. Some administrators had responded with confirmations. Now an administrator has contacted me on the blog, and posted a solution that works for him, which I am adding as an addendum.
[German]Since Microsoft and Windows system administrators are investing more in macro security, attacks via this vector are becoming more difficult. Cybercriminals are looking for new ways to deliver malware to users. OneNote occupies a prominent position as a gateway – but other files and the Mark of the Web vulnerability in Windows have also been increasingly used for attacks recently.
[German]A couple of days ago a German user contacted me with a strong observation. On a fresh installed Windows 11 22H2 he received an event log entry that says (translated) "Windows Security Health Service exe no longer functioning". In addition, there are display errors in the Defender settings page. The strange thing is that the error happens to one user right after rebooting the system. It seems, that a Defender update brokes something.
