now windows 10 fells better , had cracked win 10 i installed So on my laptop i had win 8.1 pro ( Windows 8 1 8in1 x86 x64 en-US May2015-murphy78 ) did my activation had only unziped ISO upgraded it signed in with new MS account did 2 updates rebooted , then i used rest this pc option and now it FLYS.
After latest update (KB3074681), C:\Windows\System32\InstallAgent.exe was running in the background for about 10 minutes. USB3/Hub version was changed to 10.0.10240.16399.
That p2p option must really speed up the windows delivery I wonder if it's been secretly added to 8.1 and 7
in win updates/advanced options/choose how updates are delivered/pc's on my local network and pc's on the internet.
They need all the help they can get depending on how many of those billion pcs they want to upgrade at a time.
