How do I remove all the software that I shows in INVENTORTY so that I can do a new scan?

2 Spice ups

You don’t, you just do the rescan and it will update itself removing anything that isn’t still there.

Step 1 and 3 in the inventory inconsistencies How-To should also help with that, assuming that Spiceworks is also scanning the correct device without errors.

I thought that was how it worked, but it keeps the old Devices there. Is there some check box that needs to be checked? I have some devices that have not been here for 6 months but they still show up.
