I don't necessarily agree with everything I've read here. Yes, in general most of it is accurate AND I fully agree that having a larger drive should be a priority because in this day and age anything less than 200GB for the primary drive is usually either asking for these kinds of problems, for most systems, or means you have a really old drive, but, my primary drive for the OS is only a 250GB drive, and while I'm running Windows 10 and have a SLEW of programs installed, including office with Excel, Word, Powerpoint, Access, Publisher, etc., Photoshop, Paint shop pro, Steam, Bethesda, Epic game launchers, Acronis true image, Alldata automotive shop management, Audacity, DVD fab, Chrome, Firefox, Opera, Displayfusion, Clipboard fusion, Adobe illustrator, Adobe dreamweaver, Canon digital photo pro, Paragon partition manager and a bunch of other high end applications, I STILL only use about 62GB of space on that drive.
So I find it hard to believe that if they only have Windows and a few programs installed that they would be running out of space on there. There is either something wrong, or it's from System restore and other OS related bloat that hasn't been cleared out because the OP doesn't know how to.
I've literally cleared out 50 or more GB of system restore points from people's systems I've worked on before. Also, the Windows.old folder. That can be 20-30 GB or more.
What Windows version are you running?
Did YOU install Windows on this machine, or was it already installed when you got it?
There are some additional things that can be done, that you have not yet done, to clear out some space, but if you are going to get a larger drive anyhow it might not make sense to bother with it at this time BUT you will still want to do it anyhow AFTER you get the new drive and put a fresh copy of Windows on it, which leads to the next question.
DO you HAVE a licensed copy of Windows to install from, or are you going to need to create installation media using the Microsoft media creation tool in order to do the job? In other words, do you have a Windows disk or flash drive that you purchased or did this machine already have Windows on it when you got it? Is the copy of Windows on it attached to YOU, by way of a Microsoft account, or no, or you don't know? Because this is rather an important factor.
I mean the option is probably there to simply clone what you have now to the new drive, but if there is some problem, or infection, or whatever, on there now, you will just be moving that same problem right to the new drive and will likely be back in the same situation before long so a clean install is a much better option the majority of the time. But you can't sensibly do that if you don't have Windows attached to you or have valid installation media to do it with that has it's own product key on it.
Also, for future reference, all of the standard cleanup operations can be found at the link below. At least, the ones that I generally use and recommend.
If you are looking to clean up Windows 10 after an upgrade or clean install, or just as a good general maintenance priority, there are some things you can do to streamline operations and remove unwanted junk. Most of it is pretty standard, similar in nature to previous versions of Windows but...
