Unable to Completely Un-install Opera-Browser

April 13, 2011 at 03:52:17
Specs: Windows XP, 1GB-DDR1
I am using Opera-Browser and for some reason I have to un-install it completely.
Right now! I have tried un-installing it twice, using following options,

1. From Control-Panel>>Add Remove Programs.
2. Using an Uninstall-software.

Both the times, my-PC assured me of its complete removal and yet after restarting the PC, I found saved-HTML-pages flaunting the Opera-icon (which they should not do, if the Opera has really left my-PC. Right?!). Then, what does this mean? Of course! Opera has not gone out of my-PC completely. So, next what I did was to search all the Opera-installed/installation-files in C-drive (in Program-files & Windows folders) and delete them manually. But this didn’t help either i.e. saved-HTML-pages were still found flaunting the Opera-icon.

NOTE: One more proof for my suspicion-theory, comes from the fact that, all the speed-dial-links that I had set prior to uninstalling-the-Opera, were found to be intact even after its un-installation/re-installation-process (which I feel should go to the default-values, after the un-installation/re-installation-process).

What I want to achieve is that,

1. Upon un-installing Opera and then restarting my PC, I do not wish to see its icons, representing the saved-HTML-files.
2. Further, when I re-install Opera I expect to see the default values of the speed-dial-links.

Fulfillment of these 2 points, will fairly assure me of the authenticity of the un-install/re-install procedure that I have followed.

Experts! Please help me out of this and Thank-you in advance.

Phew! This Question of mine, has taken a lot of space here. I was not expecting it be so big. Everyone! Please tolerate the bulkiness of this Question. It’s just that I did not want to overlook any detail while reporting this problem.

Install opera then uninstall it using revo uninstaller(it scan and wipe remaining files). After that i beleive ie should take control of html files, if it doesn't open it and it should ask u.

The HTML file icon may not be an Opera left-over, but a Windows cache... different beast.

Programs often leave files for various settings in case you reinstall the program later on and want to revert back to what you had. Saved games files are often left behind. I second using Revo Uninstaller Free but be careful when using any tool that modifies the registry.

Good point, IMpatient.

Thank you very much for your suggestions.

OK! So there seems to be a consensus on the Revo-Uninstaller.
I’ll try that.

But hey Xps86! The rider (but be careful when using any tool that modifies the registry.) has managed to scare me. Will you please elaborate, as to what exactly I should be careful about, while using the Revo-Uninstaller?

It's not specific to Revo Uninstaller but registry modifications in general. Incorrectly adding, modifying, or deleting registry keys can cause problems as high as requiring a Windows reinstallation.

I've seen programs that try to clean the registry and suggest deleting a common entry; one that's used by multiple programs and not just the one I want to remove. So removing it would cause those other programs to have trouble.

Some programs that clean the registry, like the popular CCleaner, include a prompt before cleaning that backups the registry entries suggested to be deleted. So if there's a problem, you can usually put those deleted entries back.

The free version of Revo Uninstaller has 4 levels of cleaning depth, with the last two checking the registry. Last I checked, it doesn't backup the registry prior to deleting entries, so do a good look at what you're deleting before you do so. Since you're completely removing Opera, you can safely delete any sub-directories and entries of an Opera folder.

I've never had problems from using Revo which is why I also recommended it, but I just wanted to throw that point out there as more people are looking to completely remove old programs and freshen up their computers. I don't predict you'll have problems using Revo Uninstaller Free.

Used the Revo-uninstaller to uninstall Opera & following was the procedure that I followed,

• Used Advanced-mode of Revo to uninstall the Opera.

• Just like you said, it uninstalled the Opera following a 4-point program & then set out to scan for the leftovers.

• Now this is important,
After scanning it flashed a page saying “Found leftover registry items” and asking me to selectively delete the unwanted entries. Courtesy to my amateurish-instincts! I freaked out at this point (Forgive me! Registry is all Hebrew to me) and took a safe way out by deleting none!

• Lastly, Found leftover files & folders- I deleted them all.

All this, provided me a partial-solution to my problem i.e. HTMLs still portray the Opera-icon. The only gain was that, when I reinstalled the Opera; I found the default-values assigned to the speed-dial-links.

I guess! I need to undergo some more drills (on Registry-part). What do you say?

Using my virtual computer, I ran two tests. The first was the default installation options, which set Opera as my default browser. After installing, I noticed my HTML files got the Opera icon too. I opened up Revo Uninstaller 1.92 Free and set to uninstall Opera using the Advanced mode. When the Opera un-installation wizard popped up, I checked "Delete Opera user data". Then I clicked Details and verified all the options were checked. The Opera wizard completed and Revo moved on.

While scanning for leftover data, Revo found a total of 149 leftover registry entires/directories spanning across 3 hives: hkey_classes_root, hkey_current_user, and hkey_local_machine.

In the Classes_Root hive, there were sub-directories for various file types like .htm, .html, .mht and some Opera-specific ones. Those are all good to delete and where the problem lies.

The Current_User hive had 5 keys and 1 registry directory referencing files in the C:\Program Files\Opera folder, so all those are safe to delete.

The Local_Machine hive had 1 entry called "Opera Software" which is also safe to delete.

So it looks like Revo did a good job identifying registry files. On the Registry removal screen, you can click the Select All then Delete buttons and move on.

Revo also found two leftover Opera files/folders, one was a file in the Opera program files folder and the other was the Opera program files folder itself. Delete 'em both.

After Revo finished, I noticed some web files still had the Opera icon and other web files had the "blank icon." So I opened my favorite web browser (Firefox) and used the "Set Firefox as default browser option." Afterward, my icons changed to the preferred Mozilla icons.

For my second test, I unchecked the option to make Opera the default web browser. Before you click the "Accept Terms & Install" button, click Options and un-check "Use Opera as default browser." After the install, my icons didn't change to Opera icons.

I followed the exact same steps to remove Opera with Revo and this time it only found 7 registry entries. None from the Classes_Root hive. The other two hives had the exact same entries listed, so they were removed. The files/folder step also found the same 1 file and 1 folder, so they were deleted.

With the process complete, my icons were just as they should and I didn't need to set another browser as default.

In summary, Revo did a great job identifying registry keys to delete, so it's safe to delete all that it identifies. Thanks to my test, I remembered that Revo also creates a System Restore point before removal, so you're pretty safe if there is a problem. A Restore point includes a registry backup.

If you set Opera as default during install or anytime during it's use, it will change the file icons. So after uninstalling, open your favorite browser and set it as default, and that will fix your file icons.

If you never set Opera as default, you won't have the web file icon problem.

Aha! Thanks a lot for taking pains, to explain (in detail) these things. I really appreciate that.

I will now, myself try out all those things that you have mentioned & get back here with the results, soon.

I tried-out all that you had mentioned. And yes, you guessed it right! I had set Opera as my default browser. Now let me explain (in 2 parts) what I did,

Using Revo-Advanced-mode, I uninstalled Opera (& also deleted all the leftovers). But the end-result was same. No success. Then I noticed that, while uninstalling it did not ask me to "Delete Opera user data".

• So next I updated Opera to its latest version.
• Then set-out to uninstall it with Revo-Advanced-mode.
• This time it flashed "Delete-Opera-user-data option", to which I submit completely.
• Further I also deleted all the entries that were offered to me, after the Left-over-scan.
• And guess what! All the HTML-icons went faceless after that.
• Then I right-clicked on a HTML-file & opened it with Google-Chrome (while doing so, I also checked the option saying “Always use the selected program…”.
• Later I reinstalled Opera with the option "Use Opera as default browser" unchecked.
• Lastly, using Revo-Advanced-mode, I uninstalled Opera & deleted all the leftovers.
• And EUREKA!! I had achieved what I had longed for.

Hey Xps86! Thanks a lot for your very very fruitful advisory. It really has helped me to solve this problem completely.

Thank-You very much, once again.
