A family of Microsoft word processing software products for creating web, email, and print documents.
I am glad that worked for you. I found several postings which suggested doing it, so it was the first things I tried, but as I mentioned it had no effect at all on my system when saving files and navigating through text. Both operations remain glacially slow. I still saw an hourglass every time I would navigate in the document, even if just moving the caret by a single letter. And I remain a bit skeptical that Word is using the GPU when saving files to disk, but am open to the possibility.
Does your document contain macros?
