When trying to start install and restart my laptop to try which one was the problem I noticed that I couldn't access windows features as they were froze for around 25-30 minutes after restarting (I timed it) So, I left the ''Preparing to configure windows'' for around that time and it worked on one I was trying! Gonna try do it to the remaining 5 now and hopefully it'll have the same result.
As for these things freezing for 30minutes or so what could that be? It never happened until the first time I started getting the problem in the OP.
I'll report back here as soon as I find out if it worked or not.
Could try a system restore, then change the windows update settings to only install the updates you select at a time given by you. Then just don't check the updates causing the issues, and you shouldn't have the problem anymore
