Assuming you have a spare SATA slot/cable on your computer, you can just move everything over to the new SSD.

Easy to do and doesnt take long.

Crucial has a disk migration tool (I think it is Acronis True Image) that you can download and use for free.

I think the caveat on using it, is that one of your disks has to be a 'crucial' disk - so that works for you.

Pop the new SSD into your computer (with power off of course).

Start the computer and download the migration tool - it is pretty much just follow your nose - and it clones everything onto the new SDD.

If you go to www.crucial.com and type "migration" into the search bar - several howto guides come up (desktop/laptop/ultrabook).

If you think your windows is running ok and everything is the way you want it - then migrating is easy.

If you dont have a spare SATA slot I guess its a fresh windows install for you!

EDIT: The old disk will be left intact. Your PC will be soooo much quicker on an SSD.

While it's a PITA to re-install all the apps & configure everything just so ...

Windows does benefit from a fresh install if the original install is 3+ years old.

This video gives a really easy to understand walk-through using the free trial of Macrium, which is fully functional. I did this a couple of weeks ago, and it worked perfectly. 

For cloning I always use Macrium Reflect.   Another option is Easus Partition Master (website appears to be down). 

Second (or is it 3rd now) Macrium

^^cool tip guys, will look into it myself

XP benefited from a reinstall every so often but since Windows 7 and SSD's I don't see the point. My personal PC OS I think was fresh in 2016, runs fine - I try keep the junk files to a minimum etc. 

I cloned a laptop HDD recently with W7 installed in 2010, I installed W10 over the top cloned it to an SDD (new machine) no worries. (tho I admit installing over an existing OS is not always ideal).

I have to agree - Never really found it necessary to re-install windows.

The lift in performance in going from an old HDD to an SSD will be amazing.
