No, but if I hypothetically created and started describing a graphical windowing system as a "Windows," and a word processor as a "Word," Microsoft would surely complain. It seems a bit hypocritical to complain about others' dilution of Microsoft's own marks, but then dilute others' marks in return.
This is a bit of a digression from the original topic, but seems tangentially relevant given that we're talking about Microsoft accidentally misusing or deliberately abusing a term that has an accepted meaning in the marketplace, the very purpose for which trademarks were created.
[Also, I should have added the following disclaimer to the previous comment: Disclaimer: Long ago, in a galaxy far away, I worked for a company that seemed to have a chance at invalidating the Windows trademark, but when Microsoft offered a large settlement, my former employer took the money and ran.]
