If it is not the free online MS Word Download that you would like to try, then the full version of the Microsoft Word 2007 is there for you with new features like the Smart Art Gallery and the Equation Gallery to insert new graphics and equations that you would not be able to do in Word 2003. There is also the Compatibility Checker which will tell you which feature of your 2007 version won't open in a proper way if you use an earlier version of Word for viewing the document. You can also use the Word 2007 in compatibility mode which will make you able to save it as Word 97 / 2003 document.
Another wonderful feature of Word 2007 is the creation of a Trusted Folder in which every file is treated to have come from a trusted publisher and hence, extended characteristics of a file like Macros will run unobstructed. You know that Macros are a potential source of risk but a careful and secure usage can make it a very useful tool as well. Especially for word formatting purposes, where you do the same type of formatting for many documents, you would like to automate the task to reduce the time and effort involved.
Word printing or printing from Word 2007 can be problematic at times if you see that only one specific document is not printing but the other documents prepared by the same Word 2007 software is printing fine. This can happen to any file that you create and that also for a number of times. It becomes irritating but you cannot put the blame on your printer or even the application software that is the Word 2007 but still you would like a resolution to the problem. Renaming the "normal.dot" file resolves this problem but proper technical support is required for this. In the registry, under HKEY_CURRENT_USER you will get an entry as "word" and the corresponding subkey known as "Data" subkey is useful to troubleshoot specific document related printing problems but again that is for the expert to do and you should not do anything if you are not very sure about what you are doing. You can talk to a technical support service provider to get some computer help in this context.
