Is the Windows 10 hardware requirement high?

When the Windows 10 Technology Preview was released for download, Microsoft said that if your computer can run Windows 8.1, you can install Windows 10 Technology Preview. And in order to allow Windows 10 to replace the existing old Windows system, Microsoft's hardware requirements for Win10 system are not very high. It is now OK to run Windows Vista system except Windows 8.1 device, Windows 8, Windows 7, or even earlier. The computer can run Windows 10. Simply put, old machines running within 5 years can run Windows 10 fairly smoothly. For specific hardware configuration, Windows 10 Technology Preview requires 1GHz or faster processor, at least 1GB of memory and 16GB of available hard disk space. According to the previous convention, the official version of Windows10 should meet the same requirements as the technical preview. So the landlord don't have to worry, your computer hardware should be able to upgrade to Windows10 system.
