Integrating ESU updates into a live system is time consuming. A shortcut would be to reinstall the Windows 7 using an ISO with updates integrated.
The original German article: Windows 7 x64 ISO mit allen WICHTIGEN Updates 10 November 2022. x86 auf nachfrage - Deskmodder.de
Direct download link: W7sp1x64_v22.11.10.iso - BayFiles
I recommend you download the iso and save while you still can.
For those who need modern drivers, I recommend Windows 7 image updater (The author says it only works with virgin unmodified ISO, so there is a chance it won’t work with the above iso)
