Microsoft released a new Windows 7 update to the general public. Update KB4457139 is actually a preview of the upcoming monthly rollup update and allows users to test the upcoming fixes and improvements in advance.

This patch brings four fixes to the OS. The most important one is an update compatibility improvement that should help Windows 7 users to download and install the newest Windows 10 OS version without any issues.

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

Update KB4457139 comes quite handy for all the Windows 7 users who are planning to install the Windows 10 October 2018 Update as soon as it’s available. As always, our piece of advice to all our readers is to wait for a few days before installing new Windows updates. Oftentimes, the latest updates bring issues of their own and Microsoft needs time to identify and fix them.

Apart from these OS update improvements, KB4457139 also brings three more fixes:

  • Addresses an issue with the diagnostic pipeline for devices enrolled in Windows Analytics when the CommercialID registry key, “HKLMSoftwareMicrosoftWindowsCurrentVersionPoliciesDataCollection” is present.
  • Addresses a memory leak issue that occurs when a device with a multilingual UI calls the LoadString API.
  • Addresses an issue in which all Guest Virtual Machines running Unicast dual NIC NLB fail to respond to NLB requests after the Virtual Machines restart.

The update is provided as an Optional update on Windows Update. You can also download it directly from the Microsoft Update Catalog.
