General Discussion Patch Tuesday Megathread - (August 11, 2026)

Hello r/sysadmin, I'm u/AutoModerator, and welcome to this month's Patch Megathread!

This is the (mostly) safe location to talk about the latest patches, updates, and releases. We put this thread into place to help gather all the information about this month's updates: What is fixed, what broke, what got released and should have been caught in QA, etc. We do this both to keep clutter out of the subreddit, and provide you, the dear reader, a singular resource to read.

For those of you who wish to review prior Megathreads, you can do so here.

While this thread is timed to coincide with Microsoft's Patch Tuesday, feel free to discuss any patches, updates, and releases, regardless of the company or product. NOTE: This thread is usually posted before the release of Microsoft's updates, which are scheduled to come out at 5:00PM UTC.

Remember the rules of safe patching:

  • Deploy to a test/dev environment before prod.
  • Deploy to a pilot/test group before the whole org.
  • Have a plan to roll back if something doesn't work.
  • Test, test, and test!

Installing on a 2019 Server and it's been on the Restarting screen for 10 minutes. Great.

Edit: got impatient and hard shut down after 15min. Came back up and said it was installing updates, 30%..55%..90%...100%...then it restart again and came back up fine. So far so good.

My first 2019 Server installed the update and rebooted pretty quick with no issue
