"I misread the minimum specifications" does not a faulty ware make.

Neither does "my PC runs a thousand different games but this one crashes" a faulty computer make.

Battlefield 6 won't run on your PC unless it has SecureBoot enabled. It's not included in "minimum specifications."

I don't see how that is relevant to Oblivion, nor how you'd buy Battlefield 6 plastic wrapped in a store.

Warrantyis thę same as return. If there is nothing wrong with goods, warranty does not apply. Return means return for any reason.
