Correcting Grammar for Microsoft Products and Technology

Apr 27, 2010 • 2 minutes to read

I see book authors, editors, bloggers, press, team members, and occasionally even a VP misspell our products, technologies, and features that I thought I would build and maintain a list of the correct capitalization and spelling of the most commonly misspelled Microsoft products and technologies.

These guidelines don’t apply to URLs (ex: or to code –namespaces, variables, and classes should follow the .NET Framework naming guidelines.

This list only covers capitalization/spacing rules, it doesn’t cover the correct usage of (tm) or ® symbols or the correct word usage rules. For those, refer to the trademark Web site.

Also note that I have no idea why we are so inconsistent say on keeping features/brands two words versus one word or the order of product/version/year.
