1 Buy a legal copy of MS Word or MS Office
(Usually comes on a CD Rom)
The Home & Student Edition or Home & Small business versions are the cheapest to buy
In certain circumstances if your employer buys the correct Enterprise software license employees get a cheap home use license approx £8/£16 (UK Pounds) for download or on CD version
( I got 2007 & 2010 Office Enterprise legally this way)
+1. There are no secret methods for installing a legal version of MS Office 2007 on a Win 7 system. You simply insert the install disk and run Setup.
What is the actual question here?
