[quote]I was looking through my Xbox purchase history and I saw that I had "Destiny 2: Upgrade Edition", but I can't seem to find it on the windows store or anywhere else.[/quote] That is because that particular version was a way to purchase both the Forsaken and the Shadowkeep expansions as a single purchase when Shadowkeep was originally released back in 2019 and is no longer sold as it has been replaced with the Destiny 2: Legacy Collection (which contains the Forsaken pack, Shadowkeep and Beyond Light expansions) [quote]I wanted to see if I could use that so I can play my DLCs on PC. Is there a way how I could still use it?[/quote] Expansions do not transfer across platforms, so if you are wanting to have access to any of the expansions that you already own via Xbox (console) on the PC (whether it's Steam, Epic or Xbox (PC/Windows)), then you will need to purchase the expansions on your preferred PC platform.
