If you mean the microphone noise that is always present, you can use the noise reduction filter on it so in future recordings you don't have this issue.
And of course do not force too much the audio level in windows advanced audio settings.
If you want to remove it from the recorded file, then you have to process the file with a proper tool. Most modern video editors have filters available for this, but the overall sound will suffer. You can also process only the audio part in programs like Audacity and then re-add it on the video via a video editor program.

Adding to that, noise reducers are not magic. They do hurt the intended sound too, and the vast majority are designed for spoken voice only. Anything else - music, sound effects, etc. - are considered as noise to be removed. Think of a business "bored meeting" in a terrible conference room or lobby, or a family call from your living room with all the other noise sources still on and probably never thought of, etc.
If you really want to do a good job, don't use a noise suppressor, but use a good noise-rejecting mic with its associated cabling and interface, and turn off all of the other noise sources. A lot of YouTubers suffer through their recording sessions, and then turn their air conditioning back on.
A noise-rejecting mic has a lot to do with the size of the diaphragm (bigger is better: it averages the air pressure over a larger area) and the pickup pattern. The most important part of the pickup pattern is not the angle(s) that it picks up from, but the angle(s) that it *rejects* from. Design the nulls to point towards the worst things that you can't get rid of or block with something solid.
For blocking sound, you might take a cue from professional rock concerts. The bits of plexiglass scattered around the drums are called "shy baffles". Their purpose is to block the cymbals' direct path into the vocal mics, without being anywhere close to a full cage, which would itself cause a big problem with reverb for the drum mics, in addition to looking stupid for that type of show anyway.
