MongoDB for Windows 64-bit runs only on Windows Server 2008 R2, Windows 7 64-bit, and newer versions of Windows. This build takes advantage of recent enhancements to the Windows Platform and cannot operate on older versions of Windows. 

MongoDB for Windows 32-bit runs on any 32-bit version of Windows newer than Windows Vista. 32-bit versions of MongoDB are only intended for older systems and for use in testing and development systems. 32-bit versions of MongoDB only support databases smaller than 2GB. 

MongoDB for Windows 64-bit Legacy runs on Windows Vista, Windows Server 2003, and Windows Server 2008 and does not include recent performance enhancements. 

To find which version of Windows you are running, enter the following commands in the Command Prompt or Pow- ershell : 

wmic os get caption 

wmic os get osarchitecture 

## Step 2: Download MongoDB for Windows.
