As always with beta/preview software, you shouldn't install it unless you're fully prepared. Here we list 10 things you should to know before downloading and installing Windows 10 Technical Preview.
1. A Preview for PC Experts
Windows 10 Technical Preview is a testing version not the final version and you might face problems such as Windows crashes, freezing while using the OS. Moreover, it is targeted at PC experts who understand the risks involved in downloading unfinished software.
If you don't know what an ISO file is or you don't have a separate PC to install it on, it is not recommended to install Windows 10 Technical Preview.
2. Fully Prepare before You Install It
The preparatory work will include back your Windows OS and important data if you want to install it on a PC you regularly use and ideally you should have a separate hard drive/partition to install the Technical Preview on.
3. Sign up to the Windows Insider Program
Microsoft allows anyone who signs up for Windows Insider Program can download the build. Thus you'll need to sign up for the Windows Insider Program and agree to the terms and conditions that don't hold Microsoft responsible if you install it on a PC where you've got your unfinished dissertation and not backed it up. Your Windows 10 install will get regular updates.
4. The ISO File and Windows 10 Key
The ISO files for Windows 10 are around 4GB depending on which version you download – there are 32 and 64-bit versions of several different language versions. The Windows 10 key is NKJFK-GPHP7-G8C3J-P6JXR-HQRJR. Microsoft also offers a Windows 10 Technical Preview for Enterprise.
You only need to download one of the Windows 10 ISO files on a DVD or USB drive large enough to hold a 4GB ISO file to start the installation.

In Windows 8.1 or Windows 8 you can keep Windows settings, personal files, and most apps. In Windows 7 you can keep Windows settings, personal files, and most apps. In Windows Vista, you have to perform a clean install.
