  4. Error 0x800700c1

    Anniversary Update fails with error 0x800700c1

    Using Windows 10 Upgrade Assistant Anniversary update fails with 0x800700c1. Checking update history shows other updates are installing but Anniversary failing for the past several weeks. Troubleshooting Windows Update (both program and manual steps) has
    no effect.

    Update proceeds to 85% (very slow after 71%) at which point error 0x800700c1 is received. If "Try Again" is selected update proceeds to 71% whereupon white update window closes and blue update window opens and eventually closes with pop-up advising failure.
    Clicking OK returns to white update window with error 0x800700c1 notification.
