 Microsoft sued several parties for "contributory cybersquatting"—that is, encouraging others (through software and instructional videos) to cybersquat on domain names that infringed on Microsoft's trademarks.Microsoft prevailed in court and also established a precedent that liabilities under the Anticybersquatting Consumer Protection Act (ACPA) include contributory trademark infringement.From 1993 until 2002, Total Commander was called "Windows Commander"; the name was changed in 2002, out of fear of a lawsuit after the developers received a letter from Microsoft pointing out that the word "windows" was trademarked by Microsoft.
