NVM it's hopeless tried 3 times to install 10061 trough upgrade win 7 all failed found windlp.state file but no key in it so conclusion fail and have to wait
Note that less than 9 MB of the ESD are actually encrypted, so for anyone determined enough it may be theoretically possible to compare the ESD with earlier ESDs and rebuild the missing file tables.
Maybe Qad who compiles esddecrypt.exe knows how (to delete the <ESD> tag within the embedded XML data).
Tom Warren of The Verge is claiming 10061 would be released today. I can't link to his twitter as I don't have enough posts.
lol i was just saying each time ive gone back to 8.1 they do it coz im impatient not to wait, but for me its like a 10 min install anyway
