Add a barcode insert for Excel. Rather than relying on 3rd party applications.
I'm surprised this hasn't been addressed by the OS team. With monitors getting so good, you can scan barcodes directly on the monitor. Why not treat common barcodes as a font type. ABC123 can be Comic Sans or Barcode 3 of 9. Flip back and forth as necessary.
Many IT departments WILL NOT install 3rd party anything. Perfectly acceptable if MS includes this.
