That many steps? WindowsKey+Break > Change computer name.
If you’re okay with three steps, on Windows 10 and newer, you can right click the start menu and generally open system. Just about any version supports rught clicking “My Computer” or “This PC” and selecting properties, as well.
You should probably read/know the actual law, rather than just getting it close. You’re probably referring to [18 USC 922 (d) (10)]((https://uscode.house.gov/view.xhtml?req=(title:18 section:922 edition:prelim)), which includes any felony-- not just shooting. That’s one of 11 listed requirements in that section, which assumes that the first requirement (a) (1) is met: not an interstate nor foreign transaction. There’s a lot more to it than just “as long as you don’t have good evience they’re going to go shoot someone”
Even after the sale, ownership is still illegal under section (g)-- it just isn’t the seller’s fault anymore.
This is basic information that should be known to any gun safety advocate. “Responsible” gun owners must know those laws, plus others backward and forward. One small slip-up is a felony, jail, and permanent loss of gun ownership/use. Are they really supposed to listen to those who can’t even talk about current law correctly?
The law can be better, but you won’t do yourself any favors by misrepresenting it.
