What is the black desktop issue?

The security updates KB4534310 (Monthly Quality Rollup) and KB4534314 (Security-only update) for Windows 7 SP1 and Windows Server 2008 R2 SP1 that were released on January 14, 2020, caused some users to end up with a black desktop background.

Windows 7: Modi Desktop-Hintergrundbild

The reason is that a stretched background image may be rendered as a black desktop. This is a direct result of the Windows updates in question. Strangely, not all users with desktop wallpapers are affected, and without stretched mode, the black screen doesn’t seem to exist. I myself installed the security-only update KB4534314 on a machine, but I cannot reproduce the bug. Users have posted comments on the German blog post Windows 7: Update KB4534310 verursacht schwarzen Desktop but have shared their observations, and this comment provides more details. What causes the bug is not yet clear.

At first Microsoft planned to deliver the fix for this bug only to paying ESU customers, but after protests decided to distribute the fix update generally. My hope that a regular February 2020 security update for Windows 7 SP1 will be distributed to all machines has not been fulfilled.

Update KB4539602 with a fix is available

Julia has informed me with this comment in the update (thanks for that). Microsoft has released update KB4539602 titled Wallpaper set to Stretch is displayed as black in Windows 7 SP1 and Server 2008 R2 SP1 for both operating systems. Its purpose is described as follows:

    guenni:

    actually the KB4539601 preview rollup update installed successfully on a test Win7 Pro system of mine and it did NOT have an ESU license on it. though I manually obtained it from the MS Update Catalog site

    as with the KB4539602 update, the KB4539601 preview rollup works regardless of ESU status
