14 DAY TRIAL // Microsoft has shipped new cumulative updates for Windows 11 devices running either version 21H2 or 22H2. The new updates are included in the February 2023 Patch Tuesday cycle, so they are both focused on security improvements.
The new updates are the following:
- Windows 11, version 21H2: KB5022836 (OS Build 22000.1574)
- Windows 11, version 22H2: KB5022845 (OS Build 22621.1265)
Microsoft does not provide too many details on the official KB pages, but the company says that security improvements are included, and this is why users should install them ASAP.
What’s new in this month’s Patch Tuesday
As the second Patch Tuesday of the year, the February release is quite heavy and is likely to keep IT admins busy.
Microsoft is shipping no more, no less than 75 fixes this month, out of which 8 are considered to be critical. The remaining 67 are rated with an important severity rating.
Microsoft says it’s already aware of exploits being available in the wild for three important vulnerabilities. They come in the form of a Windows Graphics Component elevation of privilege, a Windows Common Log File System Driver elevation of privilege, and. Microsoft Office security feature bypass.
The new Windows 11 cumulative updates also come with a warning for IT admins. Microsoft says that, in some cases, these updates might not show up on some devices.
“Updates released February 14, 2023 or later might not be offered from some Windows Server Update Services (WSUS) servers to Windows 11, version 22H2. The updates will download to the WSUS server but might not propagate further to client devices,” the company says.
“Affected WSUS servers are only those running Windows Server 2022 which have been upgraded from Windows Server 2016 or Windows Server 2019. This issue is caused by the accidental removal of required Unified Update Platform (UUP) MIME types during the upgrade to Windows Server 2022 from a previous version of Windows Server. This issue might affect security updates or feature updates for Windows 11, version 22H2. Microsoft Configuration Manager is not affected by this issue.”
A full fix for this glitch is already in the works, but Microsoft says IT admins can mitigate it temporarily by adding file types for Unified Update Platform premises.
