Windows 10 build 10041 apparently does have some bugs, but none of them have cropped up in my installation. Everything seems to be running fast and smooth on my laptop. Build 10041 expires on October 1, 2015.
Windows 8.1? I consider it to be one gigantic bug. Windows 8 was even worse, in my experience.
@ika, if you take a look at the below link you will see Brink as quoted a lot of text, towards the bottom of that you will see details of things that have been fixed in this build and known problems with this build...
Windows 10 Technical Preview Build 10041 now available - Windows 10 Forums
You can also take a look at this thread...
Windows 10 build 10041: Known Issues - Windows 10 Forums
As already mentioned, if you have a spare machine or don't need your machine for anything important and are happy to play with this preview then go for it otherwise wait for final release.
You can always have a play with it in a virtual machine if push comes to shove, if you need assistance with this just ask the question in the forum and many of us will be happy to help.
Hope this helps.
The ISO is on the web, , so why not just download it?
I installed it separately with big plans of making it a day to day OS. But I had to switch back to 7 a lot.
If you have a separate machine or spare hard drive, install it separately. But if you just want to check it out, install it on Hyper-V or any virtual machine.
I had issues with it to start with -- hence that post I made -- now becoming a longish thread - windows 10041 nok back to 9926.
However MOST of the issues have either been fixed or a reasonable get around available. I do agree that the current start menu is unbelievably hideous, cumbersome and totally user unfriendly (probably user aggressive it should be called) and the automatic windows updates is also a nightmare - especially for device drivers.
Networking also seems a hit and miss affair but that's been an issue with Windows ever since the first "Networkable" version of Windows came out years ago --Windows 3.11 for workgroups so nothing new there.
It IS designed as a TEST system -- if people are using this as their "everyday" or working OS then they have only themselves to blame if programs they need to use daily don't work properly.
On the whole it IS useable --IMO I would rate build 9926 as better but it's all in testing so there will be a load more builds before RTM. Also it largely depends on what you are doing with the machine -- everybody has different hardware and applications.
As both myself and badrobot have mentioned, a Virtual Machine may be the best option if you don't have anything spare.
Hyper-V is great and there is an awesome guide by Kari on how to use it here:
Hyper-V virtualization - Setup and Use in Windows 10 - Windows 10 Forums
certainly VM's are a great way to go but sometimes you need to test stuff using REAL hardware !!!!!. Fortunately I can do both. The driver issue doesn't arise with a VM if you are using VBOX or VMWARE since the Guest additions (VBOX) or VMware tools (VMware) virtualises the hardware to a large extent. That's why you need a REAL machine to check out some cases in "The Real world" too.
