Seems my thinking about correct Shutdown was old fashaoned, so now up to speed after reading this article. > http://www.howtogeek...e-power-button/
the first error looks like a coorrupted or missing file.
The second error can happen if your accessing Windows Store from a Local Account??? or do you have a Microsoft account?
The above can also prevent Windows Update from working. From you Speccy Log, there are only Hot Fixes for Windows Defender, can't see any for Windows Update.
I think we need to check windows first, then address other problems. Please insure you are connected to the mains, then run (SFC.exe)
