Welcome to Tom's Hardware, learner16!
You should keep in mind that swapping the internal HDD would void the warranty of the laptop, in case it's still covered. Make sure you notify the manufacturer's customer support in that case! Other than that, you shouldn't face any difficulties transferring the OS to your newly acquired SSD. Just make sure you
use a cloning utility that allows you to select the partition/files that get cloned. Otherwise, the automatic clone might fill your SSD with useless data. I believe
this tutorial would shed some light on the procedure.
No matter what kind of changes you make to your system or hardware, you should always backup your files before tampering with it!
If you wish to reset the laptop, you can
simply clean install Windows onto the SSD without cloning. This is actually the recommended thing to do when upgrading your primary storage! You will avoid transferring any redundant system files from your current OS installation.
Hope this helps you. Let me know if you have additional questions!
