Final answer:
To check the .NET version on Windows 10, use the Command Prompt with the commands 'dotnet --version' or 'dotnet --list-sdks' or access the key 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP' in the Registry Editor to view installed .NET versions.
Step-by-step explanation:
To check the .NET version installed on Windows 10, you can use either the Registry Editor or the Command Prompt.
Using Command Prompt
Press Windows Key + R, type cmd, and press Enter to open the Command Prompt.
Type the command dotnet --version and press Enter. This will display the version of .NET Core installed on your system. For the full list of versions, you can use dotnet --list-sdks.
Using Registry Editor
Press Windows Key + R, type regedit, and press Enter to open the Registry Editor.
Navigate to the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP in the Registry Editor. Under NDP, each .NET version has its own subkey, which contains the version number.
Although these are common methods to check the .NET version, make sure that you have the necessary permissions before modifying or viewing registry settings on your computer.
