FYI Current test system: older 3.6GHz single core. 2GB RAM. 180GB SATA. Graphics Intel 82015.
Today, this Win10 test system (build 10041 fresh installation) made the screen go black about a minute after completing the manual download of build 10049. No warning. As I'm (slowly) getting used to watching blank blue or black screens for a while within the win10 test, I waited for about an hour. Then I restarted the system, first by entering hibernate via power button and switching on again. Result: blue screen - black screen. Much activity on the disk for an hour. Second hibernate - power on: black screen. Nothing. Then I switched power off and on again to make the OS boot without hiberfil. That apparently started the 10049 update.
Now I have a slow Win10 with spartan. Very slow. About the speed you have with a 10-years-running XP that nobody ever cleaned up.
Thought about downloading build 10049 (german) to usb and do a fresh install. But where do I get the download..?? Some kind of USB / ISO updaterX86 mini app would be really cool. Look the way Kaspersky update their rescue boot sticks and merge that with the WSUSoffline tool's functionality. -- Bandwidth is limited here and every byte is worth a penny ;) Though web access is faster than last year, a 2GB DVD download takes about 4 hours and costs about $4 when I use the USB internet stick. Just can't walk down the road to my neighbour with the faster inet access everyday..
(+) boot / hibernate is faster now in 10049.
(?) activating hibernation mode apparently requires registry tweaking.
(-) Support for graphics is VERY basic. Trying to manually find a working graphics driver is a nuisance. sysdm only shows the microsoft basic adapter (software) and doesn't report the graphics hardware nor look for a proper driver. Tested on 4 different systems. At least intel (ich6 & newer), AMD-APU, and nvidia chipset (x800 & newer) working generic drivers should come with the installation, they are the most common I think ( - at least here in austria).
(?) On some systems, the same audio drivers are reinstalled on every wakeup and every boot. Should be improved.
(bug) In build 10041, resizing video playback works sometimes. Sometimes not. Inconsistent audio. Cannot test in 10049, because this build is too slow.
(?) When I push the power button and the screen is black, I assumed it's OK to power off the workshop. A simple "shutting down.." message probably had saved one of my hd's, now there are unreadable tracks -> trash bin.
(?) The ONLY way to build a bootable WIN10 USB installer on XP (or, apparently, on win7-X86) computers is by using rufus. There should be a microsoft tool that runs on X86 computers. There are some (Ahem. Lots of.) rufus download sites that try to crash your computer.
(-) PS2 HID legacy support sometimes disappears when a USB keyboard or mouse is connected. Repair needs >30min and reboots.
(+) Finally, AVIRA antivirus can be installed in build 10049, tested using the offline installer package (>160MB, not the small downloader). Lots of warnings but it works. Run the installer as admin.
(-) compatibility mode needs an improvement. I had setups reporting "Windows 1 is not supported." or "Internet explorer 5 or newer required."
(bug) spartan search is .. mostly harmless. But it doesn't find much. Or it crashes the browser. (hint: default search in IE11 is set to google)
(want that!) msi / inf installer could automagically install in the proper compatibility mode (and report that on the screen, too). Improves driver and application installation.
