Microsoft has issued a new patch for Windows 7 to address the wallpaper bug. The package KB4539602 is available to all Windows 7 users despite the fact that it has reached the end of support.
The cumulative update, KB4534310, for Windows 7, included to January Patch Tuesday, delivered a bug to the OS, making the desktop wallpaper black for many users.
After installing KB4534310, your desktop wallpaper might display as black when set to Stretch.
Since Windows 7 is no longer supported, Microsoft was not going to release the fix to the public, limiting the update to customers who have purchased the extended security update option. Thankfully, the company has changed their mind. Microsoft today released KB4539602, which resolved the issue for Windows 7 users.
Microsoft notes the following prerequisites:
- You must have the SHA-2 update (KB4474419) that is dated September 23, 2019 or a later SHA-2 update installed and then restart your device before you apply this update. If you use Windows Update, the latest SHA-2 update will be offered to you automatically. For more information about SHA-2 updates, see 2019 SHA-2 Code Signing Support requirement for Windows and WSUS.
- You must have the servicing stack update (SSU) (KB4490628) that is dated March 12, 2019 or a later SSU update installed. For more information about the latest SSU updates, see ADV990001 | Latest Servicing Stack Updates.
If your OS is affected by the bug, install KB4539602 with prerequisites to get it fixed.
