Q: how to find devices registered to my apple id

You can see what devices and/or computers that you've registered to your account by logging into your support profile : https://supportprofile.apple.com/ - is that the list that you want to see ?

I went to the suggested link and my profile has no devices listed.  Where to from here ?

Regards,

If nothing shows there then you haven't registered any devices to that account.

You might, if you've associated them to your account (e.g. through using iTunes Match, automatic downloads, redownloading past purchases on them), see a list of device names on your account : View and remove associated devices in iTunes - Apple Support

My old IPHONE 4g wont open with WINDOWs 7 why? I need my IPHONE and the screen says " connect to ITUNES and it still doesnt work......why?

I hate these steps...

should work with Windows any upgrades

If your computer's iTunes isn't recognising the phone when you connect it : If iTunes doesn't recognize your iPhone, iPad, or iPod - Apple Support

Well I noticed another device logged onto my account and I removed it before thinking about seeing who it was or where it was is there a history list somewhere

There isn't a history of devices
