WU Reset Nixes Insider Update Refusals


I just got back from a couple of days away from the office, and now I’m catching up. That means email, phone calls, and Windows updates and upgrades. My Dell XPS 2720 is an Insider Fast Ring machine that was on Build 18985. Seeing that 18990 is out, I tried to upgrade that PC through Windows Update (WU). No dice. Rebooted the machine, and tried again. Zip. Ran David Xanatos Windows Update Manager (WuMgr.exe). Nothing doing. Ran the Windows Update Troubleshooter. No luck there, either. Things started getting really frustrating when I tried to grab the build from uupdump.ml and I got an HTTP 500 error code (unidentified server problem). Then I thought to myself “Why not run the full-bore Windows Update reset and see if that helps?”

TenForums has a tutorial for that: Reset Windows Update

In case you’re not already familiar with the huge and immensely helpful collection of step-by-step tutorials over at TenForums.com, let this be a great introduction for you. OIherwise, you already know how helpful their stuff can be. As the screencap says, this particular tutorial is entitled Reset Windows Update in Windows 10. It includes a batch file named Reset_Reregister_Windows_Update_Components.bat. Run in Administrative PowerShell or Cmd.exe (Run as administrator), it walks through all of the typical activities involved in resetting the Windows Update environment, to wit:

1. Checking and stopping Windows Update services
2. Flush the TCP/IP DNS Cache
3. Delete pending updates, software distribution files, etc.
4. Reset Windows Update Policies
5. Reset the BITS and Windows Update service to default security descriptor
6. Re-register BITS files and Windows Update files
7. Set Windows Update Service, BITS and DcomLaunch to automatic
8. Start BITS, Windows Update, Application ID, and Cryptography services

The batch file does a LOT of stuff, in other words, that would be time-consuming and tedious to enact manually at the command line. And, best of all, most (or at least much) of the time, it works! In fact, it worked for me this time, too. Right now, the XPS 2720 is 64% of the way through installing 18990, having completed the download and gotten a fair way into GUI installation while I wrote this item. If it works for me, it should also work for you. Add it to your favorites or bookmarks. It is something most of us Windows users will end up using time and time again.
