If you got a new PC recently, check to see if it's running 32-bit or 64-bit Windows 7. This is especially important if you plan to use any older software (such as older electronic health record or EHR solutions) or older peripherals such as printers and scanners. I currently run 32-bit Windows 7 on all my machines because I'd rather have maximum compatibility with all older software and peripherals.
Recently, I worked with several physicians to help them reinstall Windows 7 on their newer PCs. The ones they had purchased had 64-bit software, so they had to reinstall the 32-bit OS. These days, most new PCs aren't coming with software disks, so the re-installation of an OS can be tricky.
Those of you who are still running XP may want to seriously think about switching to Windows 7. Support for Windows XP (with Service Pack 3) will be ending in 2014. Do you think you'll still have your current PCs in 2014?
