How To Remove Built-In Apps To Save Space

Hello,

So I noticed that this folder: C:\Program Files\WindowsApps
is 3.08 GB (3,318,742,747 bytes) big.

There's a bunch of apps in here that I don't use. I read a few articles online that you can uninstall apps through Windows PowerShell, and I can figure out how to do that, yet there's also ways to reinstall those apps again through PowerShell (which technically means that they don't get removed from the computer, hence keeping their "installers" on here and still taking up space).

Is there a way to permanently remove the apps in order to save space?

Thanks

I skimmed over that command when I was searching online, and still thought to myself that this wouldn't permanently remove them, yet I tried that command anyways just now.

Before running that command,
WindowsApps Folder Size: 3.08 GB (3,318,742,747 bytes)
Hard Drive Free Space: 47.6 GB

After running that command,
WindowsApps Folder Size: 2.40 GB (2,579,496,387 bytes)
Hard Drive Free Space: 48.4 GB

Which is cool! It actually worked! Yet it saved about 800 MB only, and that folder size is still too unnecessarily big.

Thanks for everyone else for their comments.
Steve C: Uninstalling them that way doesn't save space. I've done that method before.
Techjourney: Your CC comment. I've been there before, and that doesn't save space
margrave & mrgeek: Yes, you right. It's not a lot of space, yet if there's a simple process to save up 3 GB, then why not do that?
(Even though the command didn't work the way I expected it to).

So check this out, I went back in that folder and tried looking for folders that are big. I found:
A278AB0D.MarchofEmpires_3.2.0.9_x86__h6adky7gbf63m
which is 200 MB big.

I never play that game. It's a waste of space on the computer. So what else can I do to remove unnecessary folders/files that are still there?

Thanks for the reply. Good methods. Do you suggest more methods to save hard drive space?
