just tried 11.7 and makes win7 crash again, same as 12.5, safe mode crash and reset as well, but I successfully get into win7 by boot menu last good hardware config (something like that, my win7 is not english version) and confirm when into windows, service without IRST service.
P.S. all test done without win 7 updates, without service pack, without anti-virus or internet security. basicly it's a clean installed win 7
