As you know, support for Windows 7 ended on January 14 , so Microsoft is no longer working on new patches for the system. The "posthumous" update issues with wallpaper display.

The cause was patch number KB4534310, which is in Redmond. It is reported that this update causes a failure if the "Stretch" option is used when setting wallpapers. The problem manifests in Windows 7 SP1 of all editions and Windows Server 2008 R2 SP1.
The company notes that they are aware of the issue but will not address it due to the end of support. Therefore, users must either use other personalization options or pre-select wallpapers that fit the exact screen size. Stretching them further is no longer an option.
One can only hope that the issue will be resolved within the Windows 7 Extended Security Updates (ESU), as updates will be released there until 2023.
It is worth noting that and continue to use the "seven" in government structures, which means the need for paid support. Meanwhile, in Russia, the Federal Service for Technical and Export Control has already warned government agencies about the risks associated with using outdated OS. Previously, it also mentioned potential issues for banks using it.
