Total Commander (TC for short) is written in Delphi by Christian Ghisler from Switzerland. It's originally called Windows Commander, but because Microsoft always says "Windows" was theirs (in 2002), it had to change to use its current name. The reason AppNee did not recommend this edge tool before is that we thought it is more suitable for advanced computer users (lets them ice on the cake), not a beginner at all (so daunting that makes most users feel confused and uninstall it immediately).

Often someone complains that the traditional Windows logon authentication way using password is not convenient enough (especially for those PCs set up with a very complex login password), and its security is not high enough. This case, you can try Rohos Logon Key this useful tool from Moldova. It is capable of using a USB flash drive for system logon authentication. That's to say, you don't have to login Windows when it boos by inputting your password, instead, that just needs you to insert the specified USB drive.

Microsoft destroyed their classic start menu in Windows 8. Afterwards, they knew that is a mistake, so in the updated versions of Windows 10, they restored this convenient feature that every Windows user is familiar with and used to use (although they tried to hang in there to see whether it's possible to force users to be used to use their new Metro Menu design in Windows 8 and the early versions of Windows 10), even if it is still not perfect enough (just switching between Metro and desktop). This case, we have to turn to third-party software for help.

MonoDevelop (AKA: Xamarin Studio) is a free, open-source and cross-platform C# & other .NET languages IDE for rapid development of desktop & web applications on Windows, Linux or Mac OS X, and easily porting .NET applications onto Linux or Mac OS X platform from Windows.

For learning or formal development of C#, there are only two best IDE for choice at present: either the 10+ GB size of Visual Studio or SharpDevelop with only 10+ MB file size. The latter is an open-source IDE with layout similar to IDEA for Java and high flexibility & extensibility, which lets a user find everything new and fresh. It never wants to be an IDE that tries to support everything as Eclipse. Instead, it just gives you an interface, and you can do all the rest by yourself.
