outside fences, im not seeing any other bugs with this build yet, though...it could just be that i dont use any of the bugged/buggy features other then fences making explorer bork....love fences, love win 10, the good thing about this kind of thing is, by the time the changes go to rtm/general release, fences and the like will have updated or ms will have fixed whatever they did to bork them up, thanks to preview build users..
i see people talk crap about ms even offering this kind of thing.......i love it......yes it saves them money hiring testers, but it also gives them a hugely larger base of test configs that can help them spot issues that paid testers very likely would miss due to lack of specific hardware/software configs....
if it was forced, i wouldnt be happy, but, as an opt in....i can deal...either stardock will patch fences, or a new fast ring build or leak will come out, and i will move to that, since i cant roll back because...for some reason it thinks i removed the rollback files...(they are there...it just dosnt see them or something...only real bug i have found..i know a workaround but...why bother when the only thing not working is fences.. and i can deal till its updated(fences or windows...)
