Apr 12,2019I've been using jv16 for about 10 years now, and I can tell you this...you won't find a better suite of maintenance tools, and you'll never find a more dedicated R&D team! Just buy it, you won't be disappointed.

Apr 12,2019Best registry clean up software I have found! I've been using their software for several years for personal use, and couldn't find anything better yet. Also the additional features to disable spyware features from windows, uninstaller, duplicate removal, etc. Makes it all in one tool to keep the system clean and fast. Never caused my O.S. to become unstable or anything because of cleaning.

Apr 12,2019Best tool around when it comes to registry clean up. Been using JV16 Power tools for many years and I still do. Happy to see new versions of software coming up. Keep up good work up there Macecraft!

Apr 11,2019Been using for what seems like forever. Hopefully the new version will take care of those issues that have bugged me over the years. If it does, I'll change this to 5 stars. Mike

Apr 11,2019I've used jv16 power tools for many years without problems. Recently, I discovered that the "Clean and Speed Up My PC" wrecked my VPN software causing it to create two separate instances of the VPN. In anger, I demanded my money back from the VPN provider and subscribed to a different service only to find it was jv16. I no longer trust jv16 in any way. Buyer beware.

Apr 11,2019I use Macecraft Software since 12 years, and it has delivered a great service. I trust it in cleaning up my files and removing any useless registry items. Never have experienced any failures or problems with it. And also their service is recommended.

Apr 08,2019Macecraft's jv16 Power tool is a worthwhile investment to augment those found in the various folders within the O.S. With this power tool, all is at one's fingertip and delivers what it claims. A bang for your buck!

Apr 07,2019For years, this very fine company, their owner, their staff, updated and upgraded jv16PT many many times! I have always installed everything, settings are always "on demand", and so far, have never regretted running the product.

Apr 07,2019Before I discovered jv16 PowerTools, I would get incredibly frustrated with my computers. Slowdowns, freezes, crashes happened all the time, and the number of times I had to reinstall Windows was ridiculous (during one three or four month period, way back when, I must've reinstalled Windows more than a dozen times, truly ridiculous). These days, as long as I run "Clean and Fix My Computer" (now Clean and SpeedUp My Compter) regularly, not even once a week, maybe every two, three, or four weeks, I rarely have any problems with my computers. In fact, when I do have problems, using PowerTools to clean the computer and clean the registry usually takes care of them. One note though, always make backups of what you delete or fix in the registry. The one and only time I had a problem with jv16 PowerTools was my own fault: I didn't make backups of the numerous files I was deleting (which you are prompted to do each time ... my bad). Also, my start-up times are similar to what they were when I last reinstalled Windows.

Apr 06,2019JV16PT. At the beginning there was the chaos, then Jouni Vuorio issued his first program: Reg Clean? And we saw the light. It might be about 25 years ago. Since then the program has been developed to JV16PT Classic and …... beyond. I’m an old man, I spent my working life as IT H/W & S/W System Support engineer on Main Frames. Freely I can state JV16PT is the best product to support PC users to keep healthy and performant their machines, therefore safe. There is not any other program of this kind comparable to it. It’s enough to execute periodically “clean and speed my computer” tool to achive this target automatically. And you have also very helpful Registry and File tools to care your PC. JV16PT is worth a lot beacause its project engineers are people of integrity, everybody can trust in them. Use this program: for your PC it’s an elixir of youthfulness, long life and safety.

Apr 06,2019I am grateful to have used regedit. I appreciate Macecraft telling us the history. This is a tool with many options that are easy to use. It is also a dangerous tool if you don't have known good software to restore. Care must be taken to use this tool, but if you want to speed up your computer, maintain, and keep it clear of unwanted data and unused space, this is the tool. Make good backups and be brave enough to know your backups are able to restore properly, before installing and running any software that affects the operating system.

Apr 05,2019I've been using JV16 Power Tools for so many years I've forgotten when I started but definitely through multiple versions of Windows. I would never be without it to clean up and optimise my machines. I was so impressed with it I bought a lifetime licence and I won't be giving it up any time soon.

Apr 14,2019I have used jv16 for a very long time and and find it excellent. The service is great and they go to a lot of trouble to ensure you are happy. I use it weekly and over the years it has kept my PC running happily
