Microsoft has released previews of the monthly rollups for Windows 7 and Windows 10 ahead of the rollout to production devices on the December 2019 Patch Tuesday.

Windows 7 SP1 and Windows Server 2008 R2 are getting monthly rollup KB4525251, which includes just a single change, according to the official changelog on the linked page:

“Addresses an issue with evaluating the compatibility status of the Windows ecosystem to help ensure application and device compatibility for all updates to Windows.”

Other than that, it includes all improvements and fixes that were originally released in monthly rollup KB4525235 (shipped to devices on November 12 part of this month’s Patch Tuesday cycle).

Next Patch Tuesday on December 10

Windows 8.1 and Windows Server 2012 R2 are offered preview of monthly rollup KB4525252, which comes with the same change as the Windows 7 sibling, but also adds one more line to the changelog:

“Addresses an issue in which netdom.exe fails to correctly identify trust relationships when an unconstrained delegation is explicitly enabled by adding bitmask 0x800 to the trust object. The bitmask setting is required because of security changes to the default behavior of unconstrained delegations in Windows updates released on or after July 8, 2019.”

Again, it includes all improvements from KB4525243, which is the November 2019 Patch Tuesday rollout for Windows 8.1.

The new monthly rollups shipping in December will come along-side security-only updates on both platforms. The next Patch Tuesday cycle takes place on December 10.

Microsoft has also released two more preview updates, as it follows:

KB4524421: Preview of Quality Rollup for .Net Framework 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, 4.7.2 for Windows 7 SP1 and Windows Server 2008 R2 SP1 and Windows Server 2008 KB4531182: Preview of Quality Rollup for .Net Framework 4.8 for Windows 7 SP1 and Windows Server 2008 R2 SP1
