Mike7P, Like me you have "Revo" and with regard to the speed of initialization of "DoYourData Uninstaller" it also takes "Revo" a good deal of time to populate all the programs I have installed on my computer; the only exception I've found to that is "Geek Uninstaller" and when I get the funds I will try the Pro version of "Geek".

As for the registration process I have to think it's something going on inside you machine; perhaps security software.

But, in the end you would have uninstalled "DoYourData Uninstaller" and reverted back to "Revo" anyway. Like I said, the only Uninstaller I've seen to date that may be better than "Revo" is "Geek" and it populates quickly too.

Jahala, Did you register it?

Jahala,
Once you activate it with the serial key, it turns into the Pro version.

Jahala,
You may have installed the pro version before.

ric,
There was no place in input a serial.

krypteller,
Could not find anywhere to input a serial. Anyway, it's too late now.

krypteller,
Thank you. I made a note of your suggestion.

Jahala, click on the "upgrade" in the right hand corner and you will be greeted with the registration dialog. I can't say for sure, but I'm guessing it will still upgrade to the Pro version today.

JonE,
Thank you, but I already uninstalled it since I really was not interested in the free version. It would have been nice if they had said all that before I downloaded it. I have nothing but trouble anyway with GOTD and a lot of it has to do with the fact that I live on a sailboat and have to use whatever free wi-fi I can find at the various marinas where we dock. Already, I have found that GOTD doesn't work in Mexico where we are currently docked [Puerto Vallarta]. A VPN helps, but still the wi-fi at marinas tend to suck because they are shared by many boats.

Stewart Wallace, it's a problem with your machine; perhaps security software blocking it.

JonE, Thanks for reply, but I've uninstalled it. If it had been Security Software blocking it then it would have had to go anyway.

MikeR,

Good points. I could not tell if this app had a portable option and for me that's key. I use IOBIT uninstaller (portable) and it has been pretty good. I guess the only way to really tell how good the product is would to see if it would fix something that would not uninstall via Windows process.

MikeR, freeware Revo supports x64 as of August, 2016. It has been updated twice since then. And thanks for your frequent insightful comments.

JonE, Softpedia "reviews" should be taken with much skepticism.

JonE, according to the information given on DoYourData site, with free version of DoYourData Uninstaller you can uninstall 10 programs only. And Revo Uninstaller has only trial version.

JonE,
Correction.. One review and one review doesn't give you other people's thoughts on this program..

Anna, Yes indeed; I wholeheartedly agree.

Don't tell my mom, Don't Tell Your Mom What? Great Handle. DoYourDate Uninstaller FREE; will only uninstall 10 programs? I'll have to investigate that. Thanks for the heads up.

As for Revo; yeah the Pro version is a trial unless you purchase it, however Revo Uninstaller it FREE with no restrictions, other than the fact that Revo Pro will do some things the FREE version won't.

I saw a comment earlier that suggested "Geek Uninstaller" a program I was unaware of, but will investigate that, as well. And "Geek Uninstaller" is FREE and Portable.

Robert, I agree with that Robert; I tend to ignore reviews with less than a hundred or more reviews, but with that said I'm not sure what you're what review you're referring to. If you mean my blurb it's not a review, it's a comment and my opinion and my opinion only.

Don't tell my mom, Yes indeed, you are absolutely correct, you only get ten uninstalls with the FREE version; why would anyone want to try this software with that kind of limitation? We got the Pro Version yesterday and I can tell you that "Revo" and "Geek" Uninstaller out shine this and it's not even close.

JonE, Well I tried it and both "Revo" and "Geek" Uninstaller (FREE) both out shine this offering; it's not even close. I have not tried "Geek Uninstaller Pro", but if the FREE Version is any indication it may better than "Revo Uninstaller Pro" and "Revo Pro" outshines this as far as the East is from the West.

Bartolomeo, Comodo is not trusted software .GAOTD offerings are virus free.

beans, you're making an ipse dixit, comodo is among the most trusted.

Pikachu, I have lots of experience with Comodo and I know what I know. Trust GAOTD over Comodo.

beans, I must agree with you, on both counts.

Smats, Be grateful that it does because it almost wiped out all of my programs prior to receiving the the same error message. It seems to have gone into batch mode uninstall (when attempting to uninstall one particular program) and then attempted to uninstall all my programs when it fortunately crashed. It's taken me a system restore to get things back in order.

Ziggy, it seems that you select more that one program, it shouldn't have gone to batch mode by itself.

JD, any program of this nature that would let me wipe out all my programs without warning me VERY clearly that it is going to do so, is not wanted on my PC. Too easy to make simple mistakes.

Just a tip for developers: any batch delete operations should come with a warning pop up that doesn't look like a normal one, and that doesn't use the same key press. It should never be possible to do this by accident!

JD, Thanks for you feedback; I very much appreciate it. I checked for one program to be uninstalled only, but for some unknown reason when it went into clean up of residue entries it was there that it attempted to uninstall all my programs and thankfully crashed. Maybe this is a problem with Windows 10, 64 bit and one that the developers might want to look into. Thanks again for your feedback and thanks to GAOTD for offering free software which have been immensely useful over the years.

Old China Hand, Windows Disk Cleaner can stir old windows installation files, this is a software uninstaller, and not a disk cleaner.

Old China Hand, you're talking about anything, but this software!

Old China Hand, Sounds you have to learn too much about windows. Keep in mind that all application always share how to solve the problem thru google, or any forum.
Kids are better than u folks.

Old China Hand,
First things first: If you think you might want to downgrade from Windows 10 back to the previous version, don't delete that folder. Uninstall programs will not remove the Windows.old folder or previous Windows installation.

Second, unless you're seriously strapped for space on your hard drive, you don't have to do anything: Windows 10 will automatically delete the Windows.old folder one month after you performed your upgrade.

If you'd rather not wait -- if you want to reclaim that storage now -- you can delete the folder immediately, though not in the way you might expect. Indeed, if you simply click the folder and then press the Delete key, Windows will tell you you need permission, yada-yada, etc.

Here's the proper way to delete the Windows.old folder:

Step 1: Click in Windows' search field, type Cleanup, then click Disk Cleanup.

Step 2: Click the "Clean up system files" button.

Step 3: Wait a bit while Windows scans for files, then scroll down the list until you see "Previous Windows installation(s)."

Step 4: Check the box next to the entry, then make sure there are no other boxes checked (unless you do indeed want to delete those items). Click OK to start the cleanup.

Wait until it is finished and you're all done!

Susan, you wrote (in part):-

Actually, that Windows.old is the garbage forced on me by a long ago RE-installation of Win10 x32 on my Pipo Tablet when it crashed.

Luckily, I had a USB with the install Win 10 programs that partially installed my Pipo Tablet to working condition - I had to search the Net for missing drivers etc.

That left me with the garbage Windows.old compendium which takes up ~10GB on a tablet form of SSD of 64GB.

I never let this program touch any other programs there; I certainly didn't want the hair-tearing two days PLUS reinstalling.

Memo to those who MIGHT be interested in buying Chinese Tablets : DON'T !!!! [Unless you have the patience of a Saint - and the technical abilities to extract yourself from a "Tar Pit" when something goes wrong!]

Me? I'm removing this GAOTD from my Pipo Tablet this morning.

Bartolomeo, Yes - BUT - it doesn't remove ALL files that I wanted destroyed.

Claims that some are "system files" as I recall..

However, your suggestion removed the vast majority of the garbage files and almost all of the remaining files in Windows.old ..... from over 10GB down to 1.6Mbytes - so can't really complain,
