It depends on your circumstances. Continue reading to see where your business fits.
If you are currently running Windows 8:
Windows 10 is a solid operating system and a definite upgrade over Windows 8. It's much less confusing simply works better. There are plenty of new features, however it's worth the upgrade purely from a standpoint of that it's easier to use.
Be sure to check to see if all your applications and services that you use are compatible. For example, at the time of writing this blog, the ATO portal does not work in Windows 10. As always, some training is suggested so that your users get up to speed as quickly as possible.
If you are currently running Windows 7:
This is more subjective. It depends on how much the new features will benefit you and your team. Features such as virtual desktops and windows snap can help your team be more productive, however it boils down to a judgement call versus the time and expense involved in an upgrade. Our IT Managers can discuss and advise you based on your needs.
If you are currently running an older operating system?
We'd suggest getting Windows 10 with a new computer. If your computer is old enough that it pre-dates Windows 7 it's probably not worth the time and effort to do the upgrade. In addition Windows 10 is only a free upgrade from Windows 7 and 8.
