so envy u guys manage to upgrade to win10 from win7...i having hard time...not prepare to clean format yet..huhuhu

those error code when the WU is updating to win10....can't really recall the code...start with Cxxxx...i tried all steps in Redmondpie...no luck...and end up with one folder Sources (i rename to Sources.bak) in my desktop which i can't delete (1.48gb)

thanks for the suggestion. the biggest bottleneck for me is those games i had having to re-download

anyway, will try again when i finally have the time.

after the failure to upgrade to win10 via WU...i try the mediacreationtool...first attempt by choosing the upgrade option...fail, after downloading close to 3gb files...now try to make a bootable usb...lets see if this works. if still fail...i dunno what to say...i don't really want to clean install and spend hours of setting up again.

I've completed the creation of USB installer. if i use this to install win10 from within win7, will it work like an upgrade?

i give up upgrading for now....too much hassle. i think i spent like over 10gig already in download/redownload the files from WU/media creation tool. crazy...

last resort, clean install win7 >> upgrade to win10

finally upgraded to win10 from win7. it was the bloody registry mounted image that causes the fail upgrade in the last 1 week.
