You can either uninstall new version of Notepad or return to the old one using some registry trick (look it up).
Or you can download some version of Microsoft Notepad on the internet (probably not really that safe) or even ReactOS Notepad if you really insist of having such simple program, but using I’d recommend to use something like Notepad++ instead.
In my house 3 computers are already running Linux (Raspbian on Raspberry Pi, Debian testing on my PC and openSUSE on a family laptop), and I already talked with my dad to install Linux on his personal laptop as well, which is probably going to be Linux Mint (I am planning to replace openSUSE on other laptop with Linux Mint as well, because openSUSE sucks).
