    Just received this (and other updates) this morning, Australian time. All good, no hiccups to this point of time. Installed successfully on both my laptop and pc. It will be interesting to read comments here to see how others fared. These cumulative updates are great when they work, but a nightmare when they go wrong!

    Every update causes the “network’ listing under ‘MY PC’ to lose the list of the network disks (NAS). It takes a fair amount of time to re-establish that listng; sometimes I am not able to get it back and need to wait until some other update restores that listing. The disks are there and accessable but they are just not listed. Something in the update process is turning off some service that needs to be running to get that listing

    Windows installed this on its own (like usual). Now I cannot access the start menu and a few programs on my taskbar are blanked out and not accessible. Looking like linux is more and more the answer everyday. SMH.

    Won’t download or install here – stuck at “Downloading Updates 3%” and I hit Details I see:

    Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3135173)
    Waiting for download

    The Windows Update Troubleshooter says “Troubleshooting couldn’t identify the problem”

    Did MS pull the update and not tell anyone?

    @David: You might want to check the link provided below as it gives the direct download links for 64 bit and 32 bit KB3135173.

    As always check the download with your a/v. I’ve used these direct download links in the past and have had no problems with them. Note, the downloads can be largish in size.

    Locked my pc in an “orange screen of death” (orange screen w/circling dots for hours). Restored OS to date prior to update and everything worked fine. Then Microsoft forced the update again and same thing happened. I’m restoring a second time, but this is bulls&@$! Microsoft needs to put some user controls back into the update process if they’re going to deliver half-baked code.

    This broke my network connection to QuickBooks, saying it might be a firewall issue even though the firewall is turned off.

    Broke my browsers….can ping websites, browsers won’t work….so frustrated.

    • Ziggy June 22, 2016 at 6:43 pm #

      @Brenda: What browsers are you specifically talking about? Both Chrome and Firefox have a feature where you can “refresh” the browsers.

      For Firefox check this link

      For Chrome check this link

      For Microsoft Edge check this link

      In relation Microsoft Edge I would be careful in using powershell scripts as they can mess things up.

      Whatever you do create a system restore point first. If you don’t use edge skip the information from the link provided.

      If worse comes to worse you may have to re-upgrade your pc/laptop. I’ve gone through this procedure and it’s pretty much a clean re-install by using the Microsoft Media creation tool. What it boils down to is upgrading an upgrade which, I know, sounds a bit silly.

      This re-upgrade method fixed problems with Store Apps on my laptop, which could not be fixed in any other way! However, it does take some considerable time to complete. Good luck!
