I have been using a computer for more than 10 years now. Still, at times I feel, how didn’t I know about this?. It’s true that technology keeps on evolving and getting better every day. As humans we need to try and keep pace with technology. We need to learn something new every day. The learning can be through the Internet, through books or through any friend who comes to your place and teaches you something that you didn’t really know about!
By introducing this new category, I plan to share some of my learnings with you. It includes some basic stuff you need to know while you are operating a computer. I hope this will benefit you in some way and make your overall computer experience a lot more enjoyable.
Let’s begin with our first computer tip for today! It talks about using Environmental Variables in Windows.
In any Windows machine, there are dynamic strings that contain information about the environment of the system. Many software programs, for example Java, Python etc use this information to place their files. There are a number of environmental variables that get referenced by programs that are useful to a user to find any information related to that computer environment.
There are basically two types of Environmental Variables:
1. User variables
A user can add, remove or modify a user environmental variable. The changes are written to the registry and get reflected immediately.
2. System variables
These variables can be modified by the administrator of the system. They are applicable to all the users. They too are written to the registry and most of the time require restarting the system to become effective.
Here are the steps to view Environmental variables on a Windows 7 machine!
Step 1: Right click My Computer–> Properties
Step 2: Select Advanced System Settings. Go to Advanced Tab and select Environmental variables.
Step 3: Click one of the following options, for either a user or a system variable.
Click New to add a new variable name and value.
Click an existing variable, and then click Edit to change its name or value.
Click an existing variable, and then click Delete to remove it.
