title says it all. The disc is in its box but the box is open, no one in the household knows if it is used. I was about to build a new computer and I might use the disc but how do I know if it is already used?

It's not a question of whether or not the disc has been used, but a question of the license key which should be on/in the box.

If you can find the sticker with the license key, you can check if the key is in use on one of the computers.

Generally, a license key can be used on up to three machines, but sometimes this is different.

If you want to know for sure whether or not you can use a given license key to activate a windows install, call Microsoft's customer support :)
