Determining your operating system and software versions

The operating system and the software versions of your computer are critical information as there may be significant differences from one version of an operating system to the next. Should you call Bell MTS Internet Services for technical support, the technician that handles your call may require this information. Additionally, your technician will need to know if any Service Packs have been installed to your operating system. Service Packs are additional add-ons to the operating system software which contain security and maintenance updates. Service Packs are usually installed to increase security, increase functionality or to tweak the original code of the program.

To determine your operating system version:


Press the Pause | Break key while holding down the Windows key.


Click the Apple icon followed by About This Mac.
