I have Windows 8 now, but the old laptop was Vista, if that's what you're asking. The address was scanned via QR-code either from InstaWallet's page, where it was created, or from blockchain.info, even though there was nothing in it at the time.
Sorry, not clear on that. I'm asking what was the software/website used by the guy that did the transfer to your first address in that restaurant.
Also why are you mentioning blockchain.info ? Was your first address hosted by instawallet or blockchain.info ? (supposing they had a wallet at that time, I don't remember)
I have no idea as to what software/website the other guy was using.
I only mentioned blockchain.info because there's a QR-Code associated with each wallet, and the transfer was done via that QR-C or one on InstaWallet if it was available with the newly created bitcoin wallet.
