Patch Management / Patch Tuesday / Windows 7

Its Back. Microsoft Re-re-releases KB4039884

Its been like watching a tennis match courtside with this latest update for Windows 7 SP1 and customers are losing, 40-love.

A botched update that was released and yanked is now once again available. On Wednesday, Microsoft yanked KB4039884 without warning and explanation – even wiping out all references to the update in its support knowledge base.

Even with this re-release, there’s still glaring known issues:

  • Due to a defect in WLDAP32.DLL, applications that perform LDAP referral chasing can consume too many dynamic TCP ports (potentially exhausting them) after installing KB4025337 and KB4025341. Applications and roles known to make these referrals may include Outlook.exe, DFSR, and others.
  • The WordPad application can sometimes crash on launch after KB4025341 is installed.


KB4039884 is ready and waiting in the Update Catalog ( for those brave enough to start testing. Of course, with its recent history, this update may again turn into a whack-a-mole scenario. But, who knows? Microsoft isn’t saying.
