By the way, I have uninstalled the latest version (7.76.80.95) of QuickTime and installed version 7.74.80.86. There is no issue.

Hi,

Did you install any third party image viewing application on the computer?

This issue might also occur if some utility software’s get installed along with certain third party applications. If you have not installed any application named 1% then you may uninstall the program from the computer. This will also remove it from the default program list.

Refer to the link for steps:

Uninstall, change or repair a program

Hope this resolves the issue. If the issue persists, you can write to us and we will be glad to assist you further.

Hi sir thanks for replying. Nope. I did not install any 3rd party image viewing app on my pc. But I uninstalled Photoshop CS5 from my PC 2 days ago because I'm not using it and its unnecessary to have it installed on my PC since I also have Photoshop CS6.

No sir I didn't find any utility/app named %1 or similar under 'program and features'.
Here are the screenshots of the programs installed on my system w/c is sorted by date installed:


btw sir the name of the app is '%1' not '1%' as I have posted in the title of the question. Sorry my bad.

Based on my last reply there is no app named '%1' under 'programs and features' and this issue is not yet resolved. I'll appreciate anyone who can give their insight to help me with this problem. Thank you.

Hi E-Vo,

This one is not so difficult. First understand the program "%1" is in your context menu using a shell key in the registry under HKEY_CLASSES_ROOT.

this how to tutorial of context menu tweek will help you understand and find the shell key. http://www.howtogeek.com/107965/how-to-add-any-application-shortcut-to-windows-explorers-context-menu/

the key structure: shell > OpenWithProgID (newer apps standard)
and backwards compatible: shell > OpenWith (backwards compatible for older apps)

Note:

when you delete the culprit shell key, it will not disturb your OS whatsoever. It only affects the context menu for a file type in Windows Explorer.
also the icon for "%1" is the default icon for an executable file in windows; not professional retail.

Microsoft also has a web page about file assosiations with solid information about these key entries of registry.
http://msdn.microsoft.com/en-us/library/windows/desktop/ee872121(v=vs.85).aspx

You can also screen capture the key text and entries text just before deleting a key you find as culprit. Test your Windows Explorer. then easily recreate shell key if it was not the one. the first tutorial shows how to create a specific key for context menu; easy to recreate a shell key.

You will find it!! it doesn't have normal display name text.

Improved Solution: I should have noticed the actual problem in the default list !!!

Documentation says Windows Explorer gathers the registerd file associations for that list. I think the best way to accomplish your goal is to select the "%1" program as default to open only .jpg files or .png files. Then launch that application and use the processes tab of Windows Task Manager.

1. Right click the process
2. Select Open file location on context menu.

The new window opens right to the program's exe file and you can check that program's properties.

3. Right click that exe file and select properties.

the General tab has its creation date.
the Details tab has Product Name and Copyright

At this point you may either change the name displayed from %1 to somthing or uninstall the program. Then reset the default program for .jpg or .png to none by entering (value not set) in the entry text for the HKEY_CLASSES_ROOT > .jpg > (Default) entry

Hope you enjoyed the previous post of how to tweek the context menu. It can still help you change that programs display text to somthing you recognize.

Hi,

please try uninstalling QuickTime for Windows and check if the issue got fixed.

this has worked for me - and it is 3rd party picture viewer, as it's been suggested.

"%1" was not the actual app name, 

but most probably broken part of app launch string from the registry.

The problem is with Windows Registry entries that QuickTime creates. Apple should correct all of the reg data that is listed below. I have started a discussion about this issue in Apple forum https://discussions.apple.com/thread/6699484
