I had my computer rebooted recently and I found out that Word 2007 among other things has been removed. Is there a way of downloading Microsoft Word for free?
well you can try some soft to get back your valide serial (if its not removed?)
You can download a trial version of the latest Office Suite directly from Microsoft.
Or why don't you try one of the free alternatives like Open Office or AbiWord
If you do rely on Microsoft Word and it's functionality I suggest to buy it. You can get a Office 2010 Home and Student licence for as low as $135
Or if you are in Australia, you can get it for $99 at http://itsnotcheating.com.au/
Rebooted, or formatted/restored. You should lose entire applications when you "reboot" your computer, unless you actually give it a boot with your foot and damage it.
Depending on your computer, you may be able to factory reset it as most computers nowadays come with Office Starter installed
this should have been for public
Not legally, the pirate bay should have plenty of downloads.
