I've been using this for years also, ... not too long ago a friend of mine kept seeing pop ups and reminders from McAfee on his new laptop. He had used the MacAfee uninstall when he first used the laptop to put his preferred antivirus. Used Revo, and it was finally TOTALLY uninstalled and had no traces of it after that. Revo works great.
Been using the Pro Version of Revo for years and its great to remove all traces of uninstalled programs and Microsoft apps that don't allow you to uninstall them
100% agree to use Revo. I have done it for over 10 years. I use image backup as you suggest, but I have never seen the program to fail. I use the agressiv way (advanced) every time i uninstall programs. No problems in that so far. Revo is the first program i put on a pc afer a fresh install. Use it to clean up the programs from Windows I don't want. Happy new year to you all :-)
No Revo don't have that tool to remove Defender. But Chris Titus tool "one Tool for everything" can maybe do it. Check video about his tool that can do a lot.@@vovazagach1781
Been using Revo for years - it finds all registry entries etc. Windows uninstall leaves tons of crap on your system. By the PRO guys - they deserve it. 👍👍👍
I had never realised I could 'select all' for the registry leftovers. After all it ticks everything, even My Computer! I've always manually ticked bolded items myself, sometimes taking quite some. A revelation for me, thanks Leo.
I used to do this myself as a precaution and to make sure only the affected spots were deleted, but evidently there is no need because he recognizes them on his own. In various videos I have always seen that people click on “select all”.
I've also been using it for many years, and was under the impression you checked of the bold entries only in the free version. I think those were the the instructions when i got it many years ago.
Well I've just uninstalled MediaMonkey I think it was it had loads of reg leftovers so used select all with no negative effects that I've noticed. This is the free version.
I too have been using Revo for many years. If I'm not mistaken I found a youtube video of Leo's years ago that talked about Revo and explained how to use it. I was impressed with his explanation so I downloaded Revo and it did a great job of getting rid of a program that I couldn't get to uninstall. I've been using it since. I use the advanced mode and it has never caused a problem. I install it on every computer I have and have always installed it on any builds or reinstalls on any computer I work on. It's so easy to use that even those who are computer illiterate can use it with confidence. I thank you Leo for the original video as well as this one. Great information originally and a great refresher this time. BTW, I have it on my win 10 computers as well and it works just as good as it did on my previous versions of Windows. I still use Win 7 of a couple of my older computers. Take care Leo and be well.
Got to also remember to update your backup or you may find the damn program "appears out of nowhere" again if you ever do a recover! Now we need a registry cleaner that actually works!
I have a DAW that was not working correctly with my audio interface after an update to the DAW. I uninstalled the DAW using the normal windows process and reinstalled the DAW. But no luck. Then I see your video and uninstall the DAW and its "hidden" files using Revo. And after installing the DAW once more, everything works! Thank you Leo! This is not the first time your great videos have helped me!
This is terrific. I've been using it for a couple of years. It's amazing what apps leave behind when they are removed. I've always used REVO to remove these files and have NEVER experienced a problem.
Been using it for years. I like to install with their install tracker if I’m unsure about a program, as it logs everything installed so everything gets removed. Regular uninstall leaves stuff behind. I also use the startup manager a lot. I know I can use task manger, but Revo more convenient.
Brilliant, helpful and illuminating technique. Thank you, Leo after 23 years of using Windows I have learnt about Revo Uninstaller- it is never too late.
your video made me really think back to try and remember how long i've been using revo, i wanna say since win 98 but that seems like a long time ago, i know i can say i haven't had a computer that didn't have revo in the last 20 years, it's one of the first programs i install on every new build whether it's my machine or a customers.
I've used this for years. It has helped me Test some questionable softs and was able to track them from install to uninstall.. Marvelous stuff for those who push the envelope on system destruction.
Been using it for quite a while now. I initially had to use the paid version to delete (used hunter mode) to remove a problem program. I can't remember what it was now. Anyway, I still have that "older" paid version installed and still use it. I'm just not updating to the latest version. But it still works fine and is a great program. I may pay for the newer version just to support them. I think that's always a good idea when you have freeware that is particularly useful to you.
Another good video Leo. Just for info, I generally reimage from a backup prior to installing "test" software, rarther thasnuninstalling the software, becasue , like you said there are registry keys etc left behind. However I did try the freeware that Revo offered and it works well. I followed your video and its all good. I removed VLC and a thing called Aimersoft (DVD ripping software) and their respective "leftovers" . It appears to have done the job well. Donald. Scotland. UK.
In the registry part only delete the highlighted ones. That’s very important. Also sometimes some other registry keys will show up that don’t have to do with the program you’re deleting.
There may be a program that you want to uninstall and you will be prompted to restart your computer to complete the uninstall, in that case I bypass it and continue with the uninstall process and I myself use the advanced uninstall.
Revo Pro is worth the price. Its an excellent tool that assists with troubleshooting and housecleaning. The free version is a one trick pony, Pro does more.
Wow, great video! Thanks! Revo does more than the Uninstall Tool I purchased back in 2021, it won't delete Windows apps but does everything else Revo does. I just downloaded the Free version including the Free Portable version. Gonna uninstall some Windows apps including all the Xbox apps 'cuz I'll never use them.
This is odd. I just uninstalled Revo today. Was watching a video by Carey Holzman and he said Revo was not good to have on your computer. I'm a bit confused on this.
As others already said. It´s on of the first programs on my computer. Revo Uninstaller is worth every penny krona dollar or whatever currency you have. It will make your life easier with computers or if I will be specific, to remove ALL that remains from a standard uninstall witch will save space and speed of the computer. To keep the computer cleen are the best thing to restore speed to originals best possible. Best regards from Sweden
Ever since I've discovered this tool, it has become a mainstay on all of my systems. Sometimes I also use the portable version at work to uninstall packages with broken uninstall scripts. And this is the only correct way to uninstall Microsoft office
I use Iobit uninstaller and, it does everything Revo does but, you can select multiple programs & windows apps at the same time & remove them all instead of having to do each one individually.
like, uh, wow leo, you've been an idol of mine for a very long time now and there you go again. i wasn't even looking for this; but i messed up an uninstall of xampp really bad i mean, i botched it up like you wouldn't believe to the point where i was gong to reinstall my o.s. (by trying to rename it so i could install another version of php) so now i can't wait to try revo uninstaller. thanks leo
I have just started using this and it appears to work great. My question is, I have previously uninstalled programs using the uninstall. How do I clean up my registry from these uninstalls or is it probably not worth worrying about?
you discuss uninstalling from the starting point of a functional application. revo has an option to search for remnants and leftovers that remain after other uninstalls. What is the value of hunting for the remnants? is it worth buying the pro version?
Depends on how often you run into situation where it matters. I've rarely had a case myself where remnants caused any problems, but I do occasionally hear from people who have.
@@askleonotenboom I read will be able to uninstall edge in the EU in March. Maybe from US with VPN? Tried to post the article but you tube would not allow it
I've not yet played with their uninstaller product, but the base toolset seems reasonable. I've been watching it for years. It's one of only two registry cleaners I feel safe recommending. (CCleaner being the other.) Normally you don't need one, but in cases where you do.
I was wanting to get rid of edge, uninstalling was a big mistake, there are too many other windows features that work of it. I have files on paid version of one drive, and you cannot post to your website unless you have Edge. I know, weird but true!
I've been using Revo for years, but with window 11 I uninstall Microsoft edge and it will always reload it over time. Do you know how to permanently uninstall programs like this completely?
Will this work to remove Co-pilot and Windows backup, and work on windows 10 Home? Keep getting prompted to log into MS account and getting sick about it.
Some programs have a trial period. After the period is expired, (and the app deleted), starting another trial period is prohibited. Something remains on my computer. Does Revo remove this?
You mean the flag that says trial period exhausted? I would think so, actually, though it'll depend on the technique used by the program. Certainly worth a try.
Before installing an application, is there any utility (Revo Uninstaller, Total Uninstall, Install Watch Pro), that can just output a summary of the changes before and after the install? i.e. a list of the Registry changes, Files Replaced, Files Added (X Megabytes).. including hidden files and those with Alternate NTFS Data Streams (ADS)?
I used it last year to uninstall MS edge and it worked great. Then after a month and I didn't buy the pro version I noticed that edge was back on my computer. So I tried to uninstall it again and it refused to work. So I uninstalled Revo. Maybe MS locked it out, don't know but I could no longer uninstall edge after that. Yeah, great program.
I can’t imagine how much clutter there is on my computer registry. I used ccleaner years ago. Now I hear there may be a problem with it. Do you have a suggestion on an alternative to ccleaner? Also, since over the years I’ve uninstalled multiple programs,including Mcafee, would Revo find the clutter and wipe it out? Thank you. 0:06
CCleaner's fine as long as you choose custom install, and pay very close attention to anything that's offered. JV16 PowerTools is another. I DON'T recommend using any registry cleaners, though. There's rarely any significant improvement, and the risk is just too high.

Hi, I've already uninstall alot of bloat from Asus and Corsair via the Windows uninstaller before purchasing Revo Pro. Do I need to reinstall the rubbish and then use Revo or is their away of Revo finding the leftovers?
How do I remove programs that weren't part of the same instance of Windows but left from a previous instance of Windows? I want to remove them cleanly. Is that available in the free version?
Should be, but it kind of depends on what you mean by previous instance. If you upgraded on top, then yes. If it's some kind of side-by-side install, then probably not.
Sometimes, you just need a bigger hammer.
i use revo for a long time now, and it not only installs your own programs but also windows things, great app, cheers Leo
Brilliant metaphor

Just wipe the hard drive and install something like LINUX Mint CINNAMON (Una) 20.3 64bit edition as there is less LINUX Malware.

There's always a danger. That's why I suggest an image backup first. However, problems seem to be very rare, so I generally go for it.
