As long as you have your Sound Forge 10 serial code, it 'should' install and activate without issue. The SCS (Sony) Sound Forge versions were not limited to just two PCs like Sound Forge 12 & 13 (Magix).
There is an SF-10 Elevated Privileges issue that occationally arises with some Win 10 PC updates, which requires a registry tweak, but I would not worry about it until it happens.. which it may not.
btw @LuisCarlos-Bona, welcome to the Sound Forge discussion group.
