Windows Subsystem for Linux

Windows Subsystem for Linux

To install WSL 2 on Windows 10 you need the following things:

• Any version of Windows 10 such as: Professional, Home or Home Single Language with the following build numbers:

Windows 10 May 2020 (2004), Windows 10 May 2019 (1903), or Windows 10 November 2019 (1909) or later. Technically you can install WSL 2 on an “insider” build of Windows 10 build 18917 or later.

• A computer with Virtualization support active on BIOS and RAM memory with at least 4GB. For best performance 8 GB.

• A processor (CPU) that supports SLAT (Second Level Address Translation):

Intel’s SLAT technology is represented as EPT (Extended Page Table). This technology is available in processors with virtualization support: core i7, i5, i3, Pentium G6950 and other appropriate Xeons. It is not available in Core 2 Duo or Core Quad (socket 775) based or other earlier Intel processors.

AMD’s SLAT technology is represented as RVI (Rapid Virtualization Indexing) technology, in their third generation Opteron processors codenamed Barcelona.
