Helping people with computers... one answer at a time.

Any program of even moderate complexity should include an uninstaller. If one does not, uninstalling can range from trivial to downright scary.

How do I remove a program that is not on the Add/Remove programs list? It is on the All Programs list but doesn't have an uninstall option. I have searched all over but can't see how.

Unfortunately this can get complicated.

Some programs don't require an uninstaller - all you need do is delete them (I'll show you how to do that for most).

Some programs should have an uninstall option and don't. That's where things can get messy.

I want to start out with a big caveat: if a program does not include an uninstall utility we have to start making assumptions. Lots of assumptions. And when we make assumptions, sometimes they'll be wrong. Most of the time the steps below will work, but sometimes they won't. Sometimes a program won't be completely uninstalled, and sometimes something else you didn't plan on will be affected by the uninstall.

Before you begin any of this, make sure you have a current backup of your entire system. These are computers: something will go wrong.

And yes, with that big a caveat to begin with, you might consider not uninstalling whatever it is you're considering. If it's not causing a problem, and it's not taking excessive disk space, then sometimes just leaving it all alone until the next reformat is the safer thing to do.

"... sometimes just leaving it all alone until the next reformat is the safer thing to do."

Not all programs add themselves to the Add/Remove programs list in Control Panel. Be sure and check on the Start Menu to see if the program you want to install has placed its uninstall option there instead.

I'll start with the simple case: programs that have no uninstaller because they don't need one. In these cases the program can be "uninstalled" simply by locating where the program is installed and deleting it.

Some very simple (in terms of installation) programs just come as a single ".exe" file. All you need to do is locate and delete that file and you're done. A lot of utilities like Process Explorer, which I refer to a lot, fall into this category.

However, most programs install to "C:\Program Files" and do so by creating a folder therein names either either for the program, or perhaps for the company that made it. For example if you've installed some program called "Leo's Power Widget" and decided you no longer needed it, you might find:

C:\Program Files\Leo's Power Widget

You can probably just delete that folder and its contents to "uninstall" the program.

One safety note: if you're not sure, rename that folder, reboot, and use your machine for a while. If no errors pop up because the software or other components couldn't be found, then that's an additional indicator that deleting might be safe.

"But what about the shortcut that's left in the start menu?" I hear some of you asking.

If you didn't put that there manually, then this is a case of a program that should have had an uninstall program, but doesn't. I can think of several reasons this might be but none of them are, in my opinion, acceptable.

When a program starts making changes elsewhere in your system - to places other than where it installed - then in my opinion it requires an uninstall program to clean those changes up. Changes include menu items, folders and data files elsewhere on your hard drive (such as "Documents and Settings"), and of course the ever popular registry.

If you want to force an uninstall of a program that does any of these things, then this is the approach I would take:

  • Backup your machine. Make sure that if the worst happens you can restore to a known state. And yes, when playing with some of these uninstall options "the worst" means rendering your machine unbootable from the hard drive. Unlikely, but possible.

  • Locate and Rename the folder containing the program you want to uninstall, reboot, and run your machine for a while. If you get errors because of the rename, then something is still depending on that software being installed. It could be a start-up entry, which we can delete later, or it could be something more critical which you may not want to play with. You'll need to decide based on the error.

  • Fix any auto-start problems that result by deleting auto-start entries from your start menu and registry as needed.

  • Delete the renamed folder. Once again reboot and run your machine for a while.

  • Scan for shortcuts to the program you just deleted, removing them from your Start Menu, desktop, quick launch bar - wherever they may have been installed.

  • Ignore the registry. I know many will disagree with me and will advocate instead searching the registry for settings that are related to the program and removing them. In my opinion it's too easy to mess up something important, and aside from start-up entries we dealt with already, there's little benefit to actually cleaning this up anyway. If you must, you're probably safer running a registry cleaning utility at this point, but I'm not a big fan of those either.

As you can see, it can get messy. It's one reason that uninstallers exist, and one reason they're difficult to get right. But in my opinion it's also really bad form for an application to really need one, but not provide it.

My general approach to uninstalling is a little different.

I do, occasionally, uninstall software that appears in my Add/Remove programs list. As you can imagine I try things, and cruft accumulates, so it's a quick and relatively safe way for me to clean up a little.

I also keep an eye on my startup programs. When something gets added, I evaluate whether I really need it long before I might delete the program. By the time I do delete something its startup entry, if it had one, is long gone.

I reformat my machine every couple of years. That uninstalls everything.

That may seem harsh and in a sense it is, but particularly for someone who tries things, who installs and uninstalls, and just generally accumulates things, "software rot" tends to set in. They system becomes just a little slower, just a little less stable. It shouldn't, but it does and after a while a rebuild and reinstall of all the software is the best way to clean it up.

And as I said, it uninstalls everything whether there's an uninstall program or not.

September 6, 2007 3:16 PM

heh.. Your right Leo, I do disagree.. The registry should be dealt with.. By not cleaning the registry, if you ever chose to reinstall the software (possibly because of a missinstall), you have not removed ALL the old entries from the previous install... As you can imagine, this definitely does cause problems as well...
Not to mention deleting the older folder only and installing a newer version afterwards... That's 2 places in the registry locking into the same files.. 2 different settings when it should be 1..

Hey Leo,

Heres a tip: if you HAVE to force a program uninstall do what Leo said and run CCleaner afterwards. It's a free program that you can download from the internet. Just google "CCleaner" and you should find it.

It usually finds all of the registry entries and invalid bits-and-pieces on your computer that don't match and cleans them up. I haven't had a problem with it and have been using it since its realize.

September 7, 2007 6:52 PM

I have some of the same concerns about uninstalling programs. Specifically, removing "all" registry keys as well. I have a couple programs that, for the most part, remove the program and clean the registry. I have Total Uninstaller and Your Uninstaller. I wish, however, that there was a program/application that "will" get "all" references to a program being uninstalled! I also run Registry Mechanic when uninstalling.

September 8, 2007 6:17 AM

A test for those who are so enamoured with "registry cleaners": try running them on a brand new installation of Wndows. One that you haven't installed *anything* on. They will still find and delete a load of keys. That's your first clue.

The fact is, there is no reliable way - at all - for a program to tell whether any particular key is junk or not. For example, naively you might think that a key that points to a path that doesn't resolve to anything is junk. A lot of registry "cleaners" think so. That's their detriment: it doesn't take a minute's thought to conceive of a number of situations where that is not the case.

And, of course, Windows is closed source. There is no way to tell whether a key is still being used by Windows. None of the registry cleaner makers have seen the Windows source code. They're just guessing.

Basically, if you run a registry "cleaner", you immediately lose all right to complain about Microsoft when your system behaves unexpectedly, crashes randomly, and doesn't work as it should. It's your own fault.

People who immediately assume that a big registry immediately implies bad performance are rather stuck in the 1970s, anyway: even Windows 1.0 only loaded into memory the parts of a file that need to be accessed rather than the whole thing; and the Windows NT line is excellent at it, as are the *nixes.

After clicking on "How do I UNinstall a program......., when one goes to the last link on the page named 'your own website' (it's in blue and double underlined) malware attempts to download immediately. McAfee Site Advisor flags this site in Red, and Spy Sweeper nails it so it can be quarantined. DON'T GO THERE!

September 9, 2007 5:01 AM

Hi Leo.
Thank you.I followed your advise and backed up the machine,then changed the names of the two programs i wanted to remove.I then shut down and rebooted and used the machine for one day without any problems appearing.The next day I simply deleted the two programs and their two shortcuts.That was two days ago and all is working ok.
Once again THANKS.

September 9, 2007 10:36 PM

Hi Leo,
Chances are that the software will have an uninstaller if it is from a a reputable source. I also check internet if there are any complaints about uninstalling problems. Sometimes uninstallers have to be downloaded separately.
If I'm not sure, I use a utility to check and record the changes made to the registry by the installed software. It takes a couple of minutes only.
I also use registry cleaners, but always in the manual mode, so I can omit any changes that could require even a new windows installation. This is not a very big problem as I regularly back up my hard disks and keep the operating system only in C:, (somewhere other than c:\windows for added security), which also increases the performance, shortens defragmentation time, etc. If a software insists on installation to c: I set it up and migrate it to another drive later.

September 10, 2007 11:06 PM

One thing you all forgot, alot of times an uninstall will get corrupt for one reason or another and simply reinstalling the program will reinstall the uninstall....then you can unintall it normally....

Hi there, I 'm having an issue while trying to boot up my both PCs. One PC is running windows Vista Home Premium and the Other one is running Windows XP Professional.

The issue is that I have tried to install and uninstall A second operating system in both of them, After successfully uninstall the OS. At any giving time I boot the computer, I still have them as a list to select as an OS, is there any idea about how I can remove them?

Your answer will be very appreciate.

hi i really need help.i installed microsoft 2007 on my computer. after this i deleted microsoft 2003 from my computer but didnt uninstall it from add or remove program in control pannel .the problem i have is when i use microsoft word and try to download a new type of sheet like a timetable, it brings me through a microsoft genuine thing saying that my microsoft 2003 is not a genuine key .i never use microsft 2003 and so i didnt have a key but now i deleted it and cant use my microsoft 2007 right.i dont really have the same problem in this article because i deleted the file in the first place ,also i not sure if i force uninstall 2003 will it uninstall 2007 .please i not great with computers i need this to be fixed.

First, it's Microsoft Office 2003 and 2007. There's no such thing as "Microsoft 2003" or "Microsoft 2007".

I'm fairly certain that deleting Office 2003 without using Add/Remove after having installed Office 2007 is the root of the problem. I would re-install Office 2007 (it may offer to repair, which you can try as well).

I have an issue that is baffling me. I have a user who has had both Office 2003 and Office 2007 installed for several months. You can have both programs installed on the same machine. However, for some reason his Office 2003 programs are no longer loading. When I look in the Add/Remove program section, MS Office 2003 is no longer there. MS Office 2007 is still there. However, the MS Office 2003 files are still on the computer. As a last resort, I wanted to uninstall and reinstall both versions again again, but since I can't find it in the Add/Remove, I just don't know what to do.

Actually having both on the machine at the same time would lead to a lot of confusion. I'd give Revo Uninstaller a try.

Leo, I have Windows 7. Would you know if it is safe to delete InstallShield via Windows Explorer, as the program is NOT in my Control Panel, Add/Remove Programs list.
I tried to install Easy Media Creator Suite 10 last night and ended up uninstalling it. With that Suite was also installed InstallShield on the fly, but InstallShield remains and I get an error message: #5 from InstallShield's Update Manager every time I boot up. I know I can turn InstallShield off in the StartUp menu, using msconfig, but I want to get rid of it completely, as no other programs are tied to it (yet) on my laptop.

No, I would not simply delete the files in Windows Explorer. Among other things that'll leave behind registry settings that are then likely to annoy you even further. You might try Revo Uninstaller.

Hey Leo,
I downloaded Windows Live Movie Maker few months ago. And when I tried looking for it yesterday, it's not there, not even in the Control Panel Add/Remove list. But when I tried downloading it, it's saying I already have it. I tried looking for everywhere, Ive scanned my whole computer with every single words that relates to it and was not successful. I've also tried deleting things that has to do with it and still not successful. And I tried downloading the RevoUninstaller and when I searched for the file, it's not there.

You'll probably find Windows Live Essentials in the list. Do an uninstall/change on Windows Live Essentials and I'd bet that Windows Movie Maker can be removed from within there.
