  1. My system is repeatedly failing in installing Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3172985). How it can be resolved?

  2. Thanks for the updated. It’s really useful to be able to download official offline installer.

    BTW, the OS Build is not «10586.495», but «10586.494».

  3. I’m constantly getting unable to install update – undoing changes. Running i7 processor with 16GB RAM, 3 SSD’s (one of which has WIN10 on it) so luckily this does not take as long as others. I also have downloaded the update from WIN Update Catalog, tried to install it – same results. Anyway to block this F****ing update? Thanks.

  4. Like Maheshwari, the installation of KB3172985 is repeatedly failing on my Windows 10 64-bit, the only error found message in the EventViewer is:
    “Installation Failure: Windows failed to install the following update with error 0x80073CF9: Movies & TV.”

    I also noticed that I am not able:
    . to uninstall the Movies & TV app
    . to update this app in the Windows Store (error code is 0x80073CF9)
