Windows Environment Variables List: Complete List on Windows 10 / 11
Windows Environment Variables List: Complete List on Windows 10 / 11. Microsoft first introduced file shortcuts in Windows 95. They were designed to add customization and make resources easier to access for users. Each iteration of Windows has attempted to propagate this idea. Operating systems should ultimately be easy to use while catering to the needs of their users. This is typically done through simplification, masking and linking. In a similar fashion to how a DNS provides an easily digestible name for a long IP Address. As you’ll see, Environment Variables ultimately function on the same principle (more or less). The following guide will explore what they are and list all of them for Windows 10 and 11. Without further ado…
Let’s start with Windows Environment Variables List: Complete List on Windows 10 / 11.
What are Environment Variables?
Before you dive into Environment Variables, you must understand what variables are in reference to programming languages. In computer programming, variables act as information containers. They point towards a resource or instruction. They essentially make it easier to reference information in a programming language. Instead of typing out information repeatedly, you place it in a variable and reference it instead. Again, they work similarly to domain names.
Environment Variables are variables defined outside of programs. This allows you to change them without modifying a program’s source code. Windows applications commonly use Environment Variables to determine where to either store or fetch data. For instance, an Environmental Variable may tell an application where to store temp files. Additionally Environment variables use a key and value format.
You can also use Windows search and run with Environment Variables. For instance, %APPDATA% is an example of an extremely useful Environment Variable that points towards the AppData Roaming folder. Instead of typing the entire address out (C:\Users\{username}\AppData\Roaming), you can just type the %APPDATA% shorthand.
Using Windows Search
- Open Windows Search (WinKey + S) or Start Menu (WinKey).
- Next, type Environment Variable into the search bar.
- Click on Edit the system environment variables. This will open the Systems Properties dialog.
- Make sure that the Advanced tab is selected and then click on the button labeled Environment Variable button.
Using the Control Panel
- Run the Windows Control Panel.
- Make sure you are viewing the Control Panel’s items as either small or large icons.
- Right click on System and select Open from the context menu.
- Click on Advanced system settings. Again, this action will bring up the System Properties Dialog.
Alternatively, you can use the search bar on the Control Panel window. Just click on it and type Environment Variables. This returns the System item along with some additional options underneath it. Click on Edit the system environment variables.
Using the Power User Menu
- Open the Power User Menu by right clicking on the Start Menu icon or pressing the Windows Key together with the X key on your keyboard.
- Next, select System from your Power User Menu.
In addition to the above options, you can also access the System Properties by using the This PC context menu. Just right click on This PC from Windows File Explorer or your desktop shortcut and select Properties.
So what are Windows Environment Variables List? Let’s find out.
