There are alternatives out there, a lot depends on what you use the machine for.
I'm not keen on Apple products (for several reasons) so unfortunately I need at least one Windows machine to run Adobe Creative Suite. Elsewhere, I tend to use Linux - its faster than Windows and as its Open Source, free to download and install.
There's various versions, most of the mainstream ones are pretty stable and have decent support if you have an issue. Long gone are the days when you needed three Masters degree in computing to install and run Linux. The ones worth considering to start with (in no particular order) are:
- Linux Mint - very similar user interface to Windows 7.
- Ubuntu - one of the most popular and superb support.
- Elementary OS - very fast and fully featured right out the box, interface similar to Mac OS.
Open/Libre Office is a free package similar to Micro$ofts Office and the documents are interchangeable between both.
Mozilla Thunderbird is a good alternative to MS Outlook.
This is an old article but it tells you a bit about the various releases:

Best thing is to use an old laptop or PC to have a play around and work out which version is best for you.
