Install/Uninstall Kali

I have yet to install Kali on my personal computer. There are some concerns I have about the installation.
If I install Kali Linux on my personal computer, will I still be able to use it. What I'm trying to say is that I take classes online, write econ papers, play pc games, etc. Will I be able to go back to my normal Windows 10 OS after installing Kali or should I purchase another computer for the installation? I don't want to be in a situation where I install Kali and everything that I have on my computer I can no longer access. Can I install Kali and uninstall it from my personal computer? I'm not sure. This is my first time actually getting into Kali. I do have the Kali Revealed handbook. I have experience in the cybersecurity field but not on Kali.

If your Windows 10 license is tied to your Microsoft account you can install Windows 10 on this computer as many times as you like
