Help how to remove "%1" application in "choose default program/how do you want to open this file?"

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

 [HKEY_CLASSES_ROOT\QuickTime.bmp\shell\open\command]

@=" "%1""

[HKEY_CLASSES_ROOT\QuickTime.dib\shell\open\command]

@=" "%1""

HI,

I had the same problem and turns out it is to do with QuickTime.

Many people have downgraded their version of QT and resolved the issue. I, however, have found a solution which means you can keep the latest version of QT AND remove the dreaded %1 from the Open with menu.

Open RegEdit and go to HKEY_CLASSES_ROOT and scroll down to the start of the QuickTime entries. You will need to go through each one and remove the %1 option from all keys. Yes, ALL the keys, and there are a few of them haha! Some of them do not have this value but to be thorough go through them all just in case...

E.G.

QuickTime.jpg > shell > open > command

and delete the entry on the right that has the %1 leaving the actual key menu location on the right (See photos for help).

This worked for me, it removed the %1 from Open With>Choose another App. I can report that there are no issues with running any apps or programs after this has been done. Result!!!!!!

I hope this helps as it took me a while to find a solution as each "solution" didn't address this issue as I wanted it addressing and digressed in to other areas of no importance.

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 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.
