So today I installed a new laptop for my niece. Fresh copy of windows 10 (home edition) on a Dell Inspiron 5558. Installation was successful, so I went ahead and installed her copy of Office 2013. The next step was, obviously, checking for updates to make sure everything is up to date before wrapping it all up. That’s what I thought anyway, soon after starting the update process I got the following error message:


…bla bla bla, something went wrong, bla bla bla…this may help (yeh right) – (0x800705b4)

September 3rd, 2017 Update:
Video tutorial now available for this fix. Watch it on TheGeneralistIT YouTube channel here.

Of course I googled it, and found some online resources with some suggestion, such as


  1. Use Windows Update Troubleshooter the debug and fix
  2. Disable any 3rd party antivirus and / or firewall
  3. Disable Windows defender
  4. The following posts at #1 – 0x800705b4 window defender error code, Post #2 – Windows 10 Service Registration is Missing or Corrupt


None of the above worked. To be honest I was ready to format and start over, but then I had my AHA moment.
