What's IBM's last pc ever?

I mean like purely IBM, not Lenovo or anything. I would just like to know for my general knowledge.

Used USB Recovery Backup from Lenovo Yoga S1 to restore my Surface Pro. Are there any side effects?

My surface got stuck in a boot loop and wouldn t go to advanced startup when I did a factory reset. I made a recovery backup on my Yoga S1, I thought this was the same as using the Windows Media Backup tool (which I've used before). It wasn't until my Surface Pro was recovered and greeted me with a Lenovo screen that I realized what happened.

It seems ok (with the exception of having Windows 8 instead of 10), but are there going to be issues that may arise since it is running a backup from another computer? Will my windows key still be valid? Any other problems?

Added (1). This used to work fine with the same Wi-Fi connection, bought it in november, just lately it is not connecting to my home network, I get that failure error after entering the password

Added (2). I haven't tried to connect to another network yet, and other Wi-Fi devices in the home can connect fine.
