Mr. M.A.G. has asked me to write this article. He likes the way that Windows XP looked. He wants an up-to-date operating system, like Linux Mint. But he wants the look that is comfortable to him, which is Windows XP.
First, you need to install Linux Mint. After you have done that, follow these easy instructions.
You will want to have these instructions on your new Linux Mint computer. Have these instructions fill up the right half of your screen. You will need a blank space on your screen later.
Theme

Click on the Linux Mint Start Menu, and choose System Settings, as shown in the picture above.
Click on Themes, as shown.

Click Add/Remove, and search for XP.

Click the down arrow to Install the theme. Click on Themes.

Click on Desktop, and choose Mint-XP. Your Linux Mint Panel now looks like the Windows XP Taskbar.
Wallpaper Background
Right-click on an empty place on your desktop. In the pull-down menu, choose Change Desktop Background. You will have folder options on the left column. If you want more options, choose the plus sign at the bottom of the left column, choose Pictures, then Open. You will now be able to choose pictures that you have collected.
Now, go to https://wallpaperhub.app/wallpapers/6852, and right-click on the ↓ WINDOWS XP Original button, choose Save Link As…, and on the left column, choose Pictures. Then click Save in the lower-right.
On a black space on the desktop (so don’t have your browser window full-screen), right-click, choose Change Desktop Background. Now Backgrounds will popup. In the Backgrounds left column, click the plus sign at the bottom. Here, Add Folder will popup. In the Add Folder left column, choose Pictures. In the lower-right, click Open. In the Backgrounds window, left-column, choose Pictures. Now close out the Backgrounds window. You should see your Windows XP background as an icon, probably the first one. Click it. Now, close out of the Pictures window. Now you have the Windows XP background.
Start Menu
You can also make your Linux Mint Start Menu icon look like Windows. Right-click on the Linux Mint Start Menu, choose Configure… > Icon. Then search for Windows. Choose mintstick-logo-windows. You’re done.
