Microsoft has just released the December Patch Tuesday updates for Windows 11 as well as all supported versions of Windows 10. If you’re already running Windows 11 on your PC, you should now be seeing the KB5008215 patch waiting for you in Windows Update.
Microsoft didn’t list any specifics in the release notes except for "miscellaneous security improvements to internal OS functionality.” As of this writing, the company isn’t aware of any known issues in this update, but we’ll let you know if that changes.
For Windows 10 users running the version 2004, 20H2, 21H1, or 21H2 of the OS, the KB5008212 patch is also available to download in Windows Update. The release notes mention the same "miscellaneous security improvements to internal OS functionality” as in the Windows 11 patch, though.
Please note that because of the holidays, Microsoft won’t offer its usual optional patches later this month. Today also marks the end of servicing for Windows 10 version 2004 for Home and Pro users, and the company now recommends updating to the latest version of Windows 10 to keep receiving security and quality updates.
