hhd to ssd

I recently built my pc 3 months ago and only bought a HDD. The HDD I bought was the Western Digital Blue 2 TB 3.5" 5400RPM Internal Hard Drive. I have installed everything on the HDD my windows 10, games, and everything else. Everyone is telling me to get a SSD. My mobo, Asrock B450M Pro4...

Hey I am planing on getting an SSD, I currently have a dell Inspiron 3760 with a HDD in that, the ssd I wanted to get was the Kingston A400 480GB SSD and I was wondering if it would fit? Thanks

So I got a pre-built a few years ago that came with the OS installed on a hard drive. I recently got a 240gb SSD and was planning on running the OS on that and everything else on the hard drive. It's probably easy, but how exactly would I transfer the OS onto the new drive with the license key.
