I did something similar while I was still working with Windows a long time ago. I had just switched to PowerShell from the basic command line and kept typing cls, which did not work. I had typed that so often it was completely in my muscle memory, and every time the ugly PowerShell error would appear. So I decided to do the proper thing and NOT alias cls to clear, but instead alias it to immediate shutdown (shutdown -f -t 0 -s iirc) and that did work eventually. Wouldn't change a thing since clear is the universal command almost anywhere so it's a lot better muscle memorizing that!
