What is Microsoft .NET Framework? Download Links for All Versions Inside

One reader asked us how to determine which version of .NET Framework is installed in our system? So today in this topic, we’ll tell you the procedure to find out installed version of .NET Framework in your Windows.

There are 2 easy way to find out the version of .NET Framework installed in your system:

  • Using Windows Explorer
  • Using Registry Editor

Method 1: Using Windows Explorer

All Microsoft .NET Framework versions are installed in following directory:

%windir%Microsoft.NETFramework

Where "%windir%" represents "Windows" directory present in the system drive where Windows is installed in your system e.g. C:Windows.

So just type the above mentioned path in RUN dialog box or in Windows Explorer addressbar and press Enter. It’ll open the directory as shown in following screenshot:

1. Type regedit in RUN or startmenu search box and press Enter. It’ll open Registry Editor.

2. Now go to:
