Updates for Windows 7/Windows Server 2008 R2

For Windows 7 SP1 and Windows Server 2008 R2 SP1 a rollup and a security-only update have been released. However, these updates are only available for systems with ESU license (2nd year). The update history for Windows 7 can be found on this Microsoft page.

Starting January 15, 2020, Windows 7 in Starter, Home Basic, Home Premium, Professional (without ESU license) and Ultimate will show a full-screen end-of-support notification. This must then be closed by the user.

As of Jan. 14, 2020, Windows 7 SP1 and Windows Server 2008 R2 SP1 have reached the end of support and will only receive paid security updates in the future as part of the ESU program. ESU license holders are advised to take a look at theWindows Message Center for details.

Microsoft has updated the Techcommunity article on the ESU program for the last time as of 12.1.2021. Note the information there about the requirements (SSU, SHA-2). In addition, the update KB4538483 must be installed manually from the Update Catalog for ESU systems (see Windows 7 ESU update KB4538483 (5.5.2020)) and at the end of July 2020 the preparation update KB4575903.  In addition, an ESU license for the 2nd year is required if updates are to be obtained beyond January 12, 2021 (also note the procedure in B4522133).

Since the updates are offered in the Microsoft Update Catalog, don’t try to install them on systems without an ESU license first. The installation fails and a rollback occurs. What does work, however: Using the BypassESU methods. ByPassESU v11 should continue to work for the January 2021 patches (see Windows 7 SP1/Server 2008/R2: Extended Support 2021 – Part 2).

Important: Starting in July 2020, all Windows updates disable the RemoteFX vGPU feature due to the CVE-2020-1036 vulnerability (see also KB4570006). After installing this update, attempts to start virtual machines (VM) that have RemoteFX vGPU enabled fail.

KB4601347 (Monthly Rollup) for Windows 7/Windows Server 2008 R2

Update KB4601347 (Monthly Quality Rollup for Windows 7 SP1 and Windows Server 2008 R2 SP1)contains (besides the security fixes from the previous month) improvements and bug fixes and addresses the following:

  • Adds historical daylight saving time (DST) updates and corrections for the Palestinian Authority.
  • Addresses an issue with German translations of Central European Time.
  • Security updates to Windows App Platform and Frameworks, Windows Hybrid Cloud Networking, and Windows Core Networking.

Compared to the previous months (to the best of our knowledge) nothing has changed for ESU systems. This update is automatically downloaded and installed via Windows Update. The package is also available via Microsoft Update Catalog and is distributed via WSUS. Details about the requirements and known problems can be found in the KB article (without ESU the installation fails, there is also a “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)” error). -Artikel (ohne ESU schlägt die Installation fehl, zudem gibt es einen “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)” Error).

KB4601363 (Security Only) for Windows 7/Windows Server 2008 R2

Update KB4601363 (Security-only update) is available for Windows 7 SP1 and Windows Server 2008 R2 SP1 with ESU license. The update addresses the following issues.

  • Adds historical daylight saving time (DST) updates and corrections for the Palestinian Authority.
  • Addresses an issue with German translations of Central European Time.
  • Security updates to Windows App Platform and Frameworks, Windows Hybrid Cloud Networking, and Windows Core Networking.

The update is available via WSUS or in the Microsoft Update Catalog. To install the update, the prerequisites listed in the KB article and above in the rollup update must be met. The update has the bugs described in KB article KB4601363. I have not found a security update for Internet Explorer 11 for this month.
