Using Fonts from own collection, want to keep them separate

I got purchased fonts and want to use them in designing. I got a question:

I want to use a font or fonts from own collection but do not want them
to be added in a folder which is already installed on windows 10. How I could do that?

Any suggestion/help in this regard will be appreciated.
Thank you in advance.

What program are you using? Some programs allow choosing Fonts from different Folders or maybe installing temporarily then delete/uninstall after use.

Hi thank you for the quick reply.
Yes you are right, I agree what you have said, that is what I had been doing on older computer.
