the latest builds 10061 -10074 all suck no good,they will not update or not running at all and go back to previous build 10049 which is running fairly good,
it seems to win 10 Preview is getting worse instead of getting better as next builds are presented,i don't think testers will put up with win 10 bullshit,what a crappy OPS they building, i think i go back to Win 7 or Linux.
Most of what I've heard about 10074 has been positive from those that can actually get it running. It may not be accurate to assume that the update/upgrade headaches are solely the fault of the new build. Cruft from old builds - corrupt/faulty Windows Update caches, funky drivers, etc - may be making it increasingly difficult to keep these Win10 installs running that have been in the upgrade cycle for months.
For my part, I tried an in-place installation from the 10074 iso. The first one failed, though this time it got all the way through the second stage of the updater before rebooting, only to boot to a black screen (monitor had a signal, it was just . . . black). I have Win10 set up to give me a bootloader, so when I manually restarted the machine after the failed upgrade, it gave me three boot options:
Windows preview
Setup
Windows preview
So I picked Setup, and it rolled me back to 10049. Then it told me I had some problem with a MIGRATE operation (all caps, I don't have the exact error message in front of me). I did look up the message, and it appears to be related to a driver problem.
So I tried again, same problem, black screen in the third part of the installation/upgrade process. This time, I selected the first Windows preview option in the bootloader, and . . . success! 10074 finished installation. Immediately after I booted into Win10 for the first time, AMD QuickStream popped up like it always does and informed me that it needed to be reinstalled, so I did, and then rebooted, and . . . now it won't boot except in safe mode. Trying sfc /scannow (which mercifully will run this time, up yours Windows Resource Protection! I win this round!).
It may be that Catalyst 15.2 from 4/1 is the reason why all those updates to 10061 and 10074 failed in the first place.
edit: Yup, it was the latest 15.2 driver. Uninstalling 15.2 AND QuickStream got 10074 to boot. It works. Now I just have to find a suitable video driver . . . I may re-try 15.2 without QuickStream to see if I can get that to work, since Windows Update is going to shove that driver down my throat constantly if I don't. Grr!
One of these days, MS is going to have to give us back configurable updates . . .
edit edit: Okay, 15.2 w/out QuickStream appears to work. For now. And all the desktop resolution problems I had with the 4/1 revision of 15.2 are gone, too, which is . . . interesting to say the least.
