VOL is the abbreviation of VOL licensing for organizations, which means "group volume licensing" in Chinese. According to this license, enterprises or governments can get preferential treatment when they need to buy a lot of software. The label of the product CD is marked with the word "VOL", so the first three letters of "VOL" are used to indicate that it is a batch.

According to the purchase quantity, this edition is further divided into five editions: Open License, Selected License, Enterprise Agreement and Academic Volume License. The Shanghai government VOL XP we are talking about is this batch purchase version. According to the VOL plan, VOL products do not need to be activated (whether upgraded to SP 1 or SP2).

TM is the abbreviation of trademark. American trademarks are usually marked with TM, which does not necessarily refer to registered trademarks. R is the abbreviation of REGISTER, which means registered trademark when used in trademark. According to China's Regulations on the Implementation of the Trademark Law, the use of registered trademarks can be marked with "registered trademarks" or registration marks on commodities, commodity packages, manuals or other accessories. Registration marks include (note plus 0) and (r plus 0). The use of a registered trademark shall be marked in the upper right corner or the lower right corner of the trademark.

So TM and R are trademarks of different countries and have no special relationship. Some domestic companies do not understand the legal provisions, blindly imitate American companies, and use TM marks on trademarks.
