Review Guide


jv16 PowerTools is a Windows system utilities suite. Originally, the program was called RegCleaner and it was released in 1998 as a freeware program. In the early 2000’s, the program was renamed to jv16 PowerTools and converted from freeware to shareware, selling for $29.95 for a copy.

The program’s name comes from the initials of its original author, Jouni Vuorio plus the age of 16 when he started to develop it. He has since legally changed his last name to Flemming, which is an old surname of his family.

The company that develops jv16 PowerTools is called Macecraft Software, which was founded by Jouni Flemming in 2002 and he is still the lead developer of the product. The company is registered and operating from Finland.

The product is not a registry cleaner, a system cleaner or a temp file cleaner. The product is a Windows utility suite that contains many features and tools, including the System Cleaner tool, which also performs Windows registry cleaning and temporary file cleaning.

The name of the product is jv16 PowerTools, not “Jv16 PowerTools”, “JV16 PowerTools” or “jv 16 Power Tools”. Please notice the lower case capitalization of “jv16”, including when the product name starts a sentence.
