Microsoft has released the Windows 10 Technical Preview and you can download and try it out. The build number for this release of the OS is 9841 (despite the fact that later builds are currently floating around inside the walls of Microsoft).
It is a taste of what will be included in the final release of Windows 10, and still is an early build. As with any non-commercial release, you should not install this OS on production hardware as there could be bugs that make some software not work as intended. If you have the ability, installing this OS inside a virtual machine is the safest option and if you can't do that, we suggest you use an older machine as a testing device and install Windows 10 on it.
Windows 8.1 specs are listed below:
- Processor: 1 gigahertz (GHz) or faster with support for PAE, NX, and SSE2
