Feb 25,2021After five years without been able install the updates of my Windows 7, the suggested methods available in the internet didn't work, I decide to try the jv16 Power Tools. Finally the problem was solve.

Feb 25,2021The program totally screwed my computer and I've had to reinstall the os and a multitude of programs and I am still in the process of reinstalling programs. Sorry, I can't give a positive review but it's important for potential purchasers to know what can happen when using this program.

Feb 25,2021Deserves the merit it gets from its users. Extraordinary developer which admits when he has made a mistake then corrects it. I have used this application for many years and have no reservation in recommending it to Windows users. Clutter (unwanted files) builds up in Windows but JV16 from this clever Finnish company keeps you working and at least postpones the need to rebuild your PC every year.

Feb 04,2021As a 10 year user of JV16 Power Tools, I can't recommend this product highly enough. On those few occasions when I can "feel" that my computer is not performing as I remember. I just run JV16 and all is back to running like a fine watch!

Feb 04,2021It helps when problems occur. It helps when performance is low. It helps when beeing unsure what to do. And support helps when nothing else helped.

Feb 04,2021It's a great tool that works like they say it does to keep your computer running safely and smooth.

Feb 04,2021I've been using JV 16 for years. It has always been an incredibly powerful tool and when used carefully can get a person out of a bind. I've always appreciated warnings when non recoverable changes could be made when using a feature. That's what I mean by carefully - JV16 is so powerful that a person needs to consider his or her actions!

Jan 27,2021I have been a user of the software since RegCleaner, and I have been following its evolution. I use jv16 PowerTools constantly to keep my computer flying. My version is for life and I recommend the app to everyone.

Feb 25,2021Upgraded to JV2020 from JV16 2014 only because of strange behaviours with the registry cleaner in Windows 10. Although I admit things are evolving in a positive way with the latest releases, I still prefer and continue to use the old version, except for the reg. cleaner. The user interface was better (clearer), there were more useful tools, evrything was faster. The actual optimizer mixes everything and the overview is misleading. Same for the duplicate fles finder. I'm only an ancient user, but I would have preferred an "actualization" and debugging of the old version. Sorry for this honest evaluation.
