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.

More work and fun, less Windows issues and troubleshooting!.
The more time you have spent with computers, the more Windows errors messages you have seen – and the more time you have spent troubleshooting Windows errors!
This is why we developed System Fixer. It’s an easy to use tool that scans your entire system for common Windows and system errors and fixes them for you.
System Fixer can automatically find and fix:
Broken file references in the registry,
Invalid or corrupted app uninstallation data,
Invalid Desktop and Start Menu shortcuts,
Invalid automatically starting apps,
Left-over files and registry keys from previously removed apps.
The built-in System Fixer feature makes jv16 PowerTools the easiest way to fix and repair Windows
Cleans unneeded files and registry data.
Allows cleaning of browser history and cookie data on domain by domain basis.
Looks for common system errors such as registry errors and broken shortcuts and allows all of them to be fixed.
Does not only clean junk but also fixes errors.
Full of unique safety features, for example, does not list registry data of currently installed apps.
Browser Data Cleaning:
The cleaning of browser data supports currently Microsoft Edge, Google Chrome, Mozilla Firefox and Opera browsers. You can choose what browser data to clean on domain by domain basis and jv16 PowerTools will automatically keep cookie data from websites that have been bookmarked. This means you can clean unneeded browser data but without having to login to every website again the next time you visit them.
Standout Feature: Accurate analysis with the focus on safety.
Allows unattended uninstallation of multiple apps at the same time.
Lists all files, folders, shortcuts and registry data relating to the installed apps.
Uninstallation first uses each app’s own uninstaller and then Software Uninstaller’s custom uninstallation engine to ensure nothing is left behind.
Standout Feature: Unattended uninstallation of multiple apps at the same time and does not rely on each app’s own uninstaller.
The program saves your time by finding data faster and easier. If it’s there, Finder will find it for you!
You can search for:
Registry keys, and
You can search for all these data types at the same time, for example to find all files and registry data relating to an installed app by searching with its name. You can also search using many search phrases at the same time and from many folders at the same time.
Windows Search can be slow and inaccurate, and doesn’t allow you to decide what exactly you want to find. jv16 PowerTools’ Finder can be configured and it will search exactly what you want, how you want!
Big File Finder
Finds big, disk space wasting files.
Supports skipping new or recently used files.
Standout Feature: More flexible set of options to allow the user to find exactly the files they want.
The program lets you get more free space by finding and removing duplicate files.
You may currently be losing a lot of disk space due to duplicate photos, or duplicate video files. You can recover disk space and free system resources by finding the duplicate files and removing them.
Duplicate files are files with identical content, although the Duplicate Finder can also look for files with identical or similar filenames. If you want to find duplicate files, this is the tool for you!
Trying to find duplicate files with Windows File Explorer or Windows Search would take ages.
With jv16 PowerTools, it takes a few seconds! After the tool has found the duplicate files for you, you can select which ones you want to keep and which delete, and the tool can clean up the unwanted duplicate files for you.
Like the Big File Finder, this tool also supports a wide range of filters for finding duplicate files. For example, you can only look for duplicate files which are over 50 MB in size and have not been used in the last 7 days.
Easy to use with a wide array of useful features. For example, searching the list of found items, filtering the result list, saving the results to list with a support for multiple file formats.
The program supports Dark Mode user interface and high resolution screens.
The program is easy to use, but it is a powerful tool for computer enthusiasts and professionals. This means it is extremely configurable with options such as hiding tools the user does not wish to use, disabling all online accessing features like checking for updates, and protecting the program installation with a password.
jv16 PowerTools does not and will not ever include any bundled software or malware.
We have been in this business for over 20 years. Our integrity is our strength. Our product is never going to include any bundled software, hidden malware features like trojan horses or spyware.
Save time by not having to manually rename files. Renaming files manually is tedious, it can take a long time and it is easy to make mistakes. That is where jv16 PowerTools comes in. It can easily rename many files at the same time, as well as edit existing file names for example by performing a find and replace with the file names. File Renamer performs what is often called a batch file rename, which is just a fancy way of saying changing the names of many files at the same time. This is something you cannot do with Windows File Explorer. Did you just download a collection of hundred files and the filenames all look like “company_document_hall_cleaning_procedure.pdf” etc? With File Renamer, you could for example remove all the “_” characters from the filenames, add text to each file or perform a find and replace within the filenames.
Ease up the transfer of large files over the internet by splitting them into smaller parts. It can be difficult to transfer large files over the internet. For example, most file upload websites won’t allow uploads larger than 100 MB. And even if you can upload bigger files, splitting the uploads and downloads into smaller pieces reduces the risk of the transfer failing and you having to restart it from the beginning. File Splitter allows you to split large files into multiple parts, either by splitting the given files into a specific number of parts, or by file size. For example, you can use this tool to split a large file into parts of 50 MB.
Benefit Ease up the merging of downloaded file parts. As mentioned with the File Splitter, transferring large files can be difficult. Splitting files into smaller parts makes it a lot easier. File Merger allows you to merge any split files back into their original state. File Merger performs what is called a binary file merging. It means it will simply append all the data together into a single file. This means it works with any file type, but it’s especially handy with large compressed files such as ZIP files and large video files such as AVI or MKV files that have been split into parts.
Prevent the need to pull your hair for not being able to delete the files you want. It can be difficult to delete files in Windows. Files can be protected against removal by many different methods. For example, “Cannot delete file, the file is open” error message is familiar to every Windows power user. Not being able to delete files can cause many problems, such as not being able to uninstall and reinstall apps. Malicious software could also try to protect itself from being removed. This is where the File Deleter comes along. It unlocks and deletes files that cannot be normally deleted, you can even use it to delete protected system files. File Deleter uses two methods of deleting locked files: First, it attempts to unlock the file and then delete it. If that fails, it can also restart Windows to delete the file before the system starts the next time.
Improves your privacy by removing data in a way it cannot be restored. When a file is normally deleted, it is simply marked as free space on your disk but the data still remains there and can be easily recovered. This can raise many privacy related problems, for example if you are selling your computer and you want to ensure it doesn’t contain any of your files. File Wiper allows you to easily remove files from your computer in a way they cannot be recovered. This works by first overwriting the data on the hard drive multiple times with random data and then removing the data. A special feature of jv16 PowerTools’ File Wiper is that it also generates fake data to make it impossible to even say what file names used to exist in your system. For example, if you use the File Wiper to delete a file called “my_secret_selfie.jpg”, the tool will first generate many similarly named files, as well as files with random English words and then delete them all from your drive. If anyone could restore the names of files you used to store in your computer, you now have plausible deniability that you didn’t have such files, that they were in fact just created by jv16 PowerTools.
Free up system resources by closing unneeded apps. Windows Task Manager allows you to see which processes are running and allows you to terminate the processes you don’t want to see. That’s good, but jv16 PowerTools can do better. First of all, Task Manager allows you to see running apps, not processes and without any background system processes filling the view. The difference between a running app and a running process is that an app can have multiple processes and on the other hand, a process may not be relating to any running app but to the Windows system itself. Task Manager also supports real-time filtering options, so you can only see the data you want to see. In addition, our Task Manager supports the automatic closing of apps and processes. For example, let’s say you want to focus on work but some apps keep showing you popup notifications. You can start the Automatic Closing feature and define which apps should be allowed to run, and the tools automatically closes everything else – and keeps them closed.
Allows you to focus on things that matter in life, also improves your online privacy. Having almost unlimited access to entertainment online is a good thing. But there can be too much of a good thing. If you feel like you would sometimes want to not have access to social media or news websites, for example, this can be easily done with jv16 PowerTools’ Web Blocker. Also, you can use the Web Blocker to block access to advertising and online tracking related services to improve your online privacy. Web Blocker can block access to specific websites. You can either choose to block all websites of certain types, for example, to block access to gambling related websites, social media websites or to adult entertainment websites. You can also whitelist websites that you want to allow access to even with the blocking enabled. For example, you could choose to block all social media websites, but allow access to LinkedIn for example. The blocking of websites works in the Windows core level using its Hosts file. This means it works with all browsers and does not rely on any running apps, plugins or browser extensions. And it won’t slow down your web browsing.
