New SSD and a clean install of Windows 10. What do I need to do pre-installation?

[TrollingKiwi]

Hi. My current system is running Windows 7 Ultimate 64 bit (pirated), a gtx 970 from evga, an i7 3300, and a 500 gb HDD. I think that's all the necessary info. Before anyone asks "WHY DID YOU PIRATE WINDOWS??" Well, I was younger and more dumb. Now I want an orifinal copy of Windows. And I want the Samsung EVO 500gb SSD. I want to get rid of this pirated version and do a clean install of windows 10. I'm ASSUMING all I need to do is install the ssd, connect the windows 10 usb, load from the usb, install Windows 10 on it and voilá. However I have a few questions:
1. Partitions: I want the ssd to have two partitions, one for Windows and the other for my data, just like my present HDD has. Will I be able to make these partitions however I want during the clean install? Or will I need to install, THEN create the partitions?
2. My Steam and Origin games, Do I uninstall them before clean install? Will I have issues if I don't and I simply format my present HDD, then install windows 10 on the new ssd, install steam and origin on it, and download the games to it? In fact is this necessary? Or is there a process through which I DON'T format my hdd, transfer my games to the new ssd, and THEN format the hdd?
3. If I DON'T format the hdd, install the ssd, install windows 10 on it, THEN connect my hdd to the pc and transfer my games...will there be an issue? I mean, the C drive on my present HDD contains a pirated windows. Will my pc when reading this partition create issues?
4. Do I need to "deactivate" any Steam or Origin games before doing this? Will I need to redownload the games later? Will there be any issues when moving my games from one drive to the other?

As you may have noticed, my main issue is my games and saves.What do I need to do pre-installation and post installation. Any tips? Thanks in advance for the answers.

First, you need to purchase the Win 10 OS.

Remove all drives except for the SSD
Boot from your install media
Install
During the install, delete ALL existing partitions, resulting in one large space
Let windows install to that space


Oh, and change all your online passwords.

Pirated OS is probably the most dangerous thing you can pirate. They might have built in a keylogger into your system.

'might have' = 'probably did'

I am really sorry for this. I was editting from my cellphone, accidentally clicked post thread, and then it crashed. I couldn't finish writing the questions until now. NOW the full question is available.

Btw, regarding the keylogger thing, is that true? I mean I've used pirated versions of Windows my whole life (Original Windows is over $600 in my country. Didn't want to pay that. However, now I have access to Amazon and online distribution. I'll be ordering everything from the US). I've never had any issues using pirated Windows so far. I had a pirated Windows XP before this, and used this pirated Windows 7 for years without issues. I'm not justifying my decision to pirate Windows, just saying I didn't have any issues doing it all these years. Do I still need to change all my online passwords? How does that keylogger thing work? Sorry for the ignorance!

Really sorry for this. Hadn't finished thequestion and posted it. I also posted an answer to explain further.

Yes, a pirated OS often includes keyloggers and other malware. It was probably there, you just did not notice it.

It was there in the background, secretly doing its thing.

A keylogger works by capturing your keystrokes, and sending that to 'some dude'.
Your username/password for your bank, perhaps.

Yes, they do that.

I see. Thank you. I will do that once I finish the clean install. Now, do you have any tips regarding the questions I editted into my original post? Sorry for the inconvenience! Thank you in advance.

From your edited original:

1. Yes, you can create partitions during the install
2. Either way. After the OS install, just log into your Steam account. It will know all your games, and you can download them again
3. You want to eventually (sooner rather than later) wipe that entire old HDD
4. No game deactivation needed. Steam or Origin games can be moved from drive to drive as needed.
Just have to tell the Steam/Origin client of the new location.
