I have a new HP computer with Windows 10.
I did the upgrade to 1607 and I think it's since then that I can't install apps from the Windows store.
For example, if I try to install Instagram a notification pops up:
Couldn't install. We'll retry shortly.
When I click on Error, see details:
Try that again
Something went wrong.
The error code is 0x80244019, in case you need it.
I have searched online for solutions, but haven't found anything related to the Windows store - most of what I find is related to Windows update - but that is working fine for me.
Edit: My last reply that this was due to some blocked ip addresses is the answer, but I can't mark my own post as the answer.
