Gary, I will have my RAM changed from 4 to 8GB by an authorized Apple Service Center. I did not deauthorize the MacBook Pro on iTunes prior to sending it in for service. It had not occurred to me to do so. Presently, I have three computers authorized, out of the five allowed on my one iTunes account. I understand that the single MBP (with the new RAM installed) may show up twice as authorized. This will show four computers as authorized. I can live with that until I want to add more computers as authorized. In the future, can I simply delete one of the MBP authorizations?

Replacing RAM and Deauthorizing Computer On iTunes

I don't see any reason why your MacBook Pro will show up twice as an authorized computer. Simply adding memory should not cause that to happen. Perhaps an extreme repair like a new processor might do it. But otherwise I don't see why ot would take up 2 of your 5 authorization spots. Why do you think so?
However, there is a common issue that someone sells a Mac or a Mac is destroyed in some way and that Mac is authorized for your iTunes account. But that is really a non-issue.
You can authorize 5 for your iTunes account. You can deauthorize any one, but you must do it on that computer. So if you don't have it anymore, then you can't. But once you have all 5 spots filled, you have the option to deauthorize ALL of them. Then the next step would be to reauthorize the ones you are using. No big deal to do that.
I read in several places online that when RAM is replaced, there was a possibility the Mac would show up twice. From Apple ht 1420 "Also, make sure you deauthorize your computer before you upgrade your RAM, hard disk or other system components, or reinstall Windows. If you do not deauthorize your computer before you upgrade these components, one computer may use multiple authorizations."
I have added RAM to two Macs and one Windows PC and not experienced the multiple PC authorizations reported. If a second authorization appears without entering an AppleID and password, something is wrong -- report a bug to Apple - see Contact US; Feedback. It is also possible a second (previous) Mac is still authorized. If it bothers the OP, deauthorize all PCs and start over.
I will pass along the result of the modification to the RAM when I get the MBP back in a week or so. In my research of my iTunes account, I discovered I had 11 devices total. The MBP is listed as a "computer authorization" as well as a "device". This results in my iTunes account showing 11 devices total, one more than the 10 allowed for the account. A bit confusing but so far had only one problem with an in-app purchase in an ios device (could not get the device to accept the IAP).
I got my MBP back from service and the iTunes account was not changed in any way. Although Apple advised there was a possibility of an additional authorization appearing, it did not happen. My account shows the same number of authorized computers and the same number of devices.
