If it's a laptop, don't change the resolution, or else everything will look crap. Leave it on the native set.
For your browser, you can increase the text size through View -> Text size. Select 'Increase' till it gets no bigger.
If you've increased the Windows text size, then everything shouldn't still be so small. Make sure it's set on Extra Large fonts in the Appearances tab.
In Word, you can use the Zoom function (the percentage thingy on the toolbar) to increase the size of the text without changing the document.
