Reviving an old thread--I'll try to make my situation / question clearer here than it is in my head...

, but first-some background.
I purchased a new T510 from the Outlet a few weeks ago. Right out of the box, it had a Fan Error message...has been sent and returned from EasyServ Depot repair. I went to set it up today, as per EasyServ instructions (which included updating drivers from both Microsoft and Lenovo). When it started up, it showed another user account on the machine. I called the Depot and they walked me through a 'restore to factory settings'.
My goal was to set up Win 7 account (single user), update drivers, and create recovery media--in that order. I did not realize the machine shipped with 30-day Norton Internet Security (NIS) subscription, MS Office (MO) Product Key preloaded.
I have purchased both NIS and MO because I wanted 'my own' copy of both. However, as I was configuring the machine, I did opt to enable the subscription of NIS. (I've read the posts on here and thought I would change it after 30 days or install my own copy--possibly
not NIS--but wanted something protecting me as I completed the setup of the machine.) I declined to activate the MO since I wanted to do a clean install of that software. (Again, I've read some of the tips for getting the freshest version on my machine using the key card I now own.)
Installing Windows updates took F-O-R-E-V-E-R (I'm talking hours--several of them)! In fact, one just downright wouldn't load and I gave up in frustration. It was a Microsoft malicious software uninstaller released this month. The error code suggested maybe it was due to heavy demand for it from their servers.
I'm almost to my question, but one more piece of info: I thought at one point that maybe the difficulty with the updates installs (since it seemed to be hanging up on Internet Explorer 9) was the NIS. Clicking that icon brought up Norton's activation screen. So far, I haven't activated it (I was never asked to until I sort of stumbled on it late in the day, when my patience was running thin).
I think my biggest question is did I screw up by choosing to use the 30-day trial of NIS
before creating the recovery media? Assuming I can (or can't) install that Microsoft malicious software removal tool tomorrow, am I still good to go to create the recovery media? I wanted to do that 'first', after creating my account with Win 7 and updating drivers. Am I still good to go, or do I need to do a 'restore to factory settings' and start over?
I'm not a super savvy computer guy--thanks in advance for your help.
