Wondering if anyone can tell me why trying to open a .jar file with Win7 Explorer ("Open With" C:\Windows\explorer.exe) would cause the computer to continually create (over 200+ in a couple seconds) explorer processes?

Thanks!

  • Never heard something about this problem! Have you tried to execute the JAR through the windows shell? Same problem? – Alberto Solano Aug 29 '11 at 20:34
  • Nope. That works. And I CAN execute the .jar through explorer, but the problem comes up when I Right-Click on the .jar and say "Open With -> Windows Explorer" – BenCole Aug 29 '11 at 20:39

Had the same problem with opening JAR files.

From here(thanks Alberto Solano):https://social.technet.microsoft.com/Forums/windows/en-US/9237ca68-645c-4718-9a51-24788f312c4b/windows-7-hangs-when-opening-a-file-with-explorerexe?forum=w7itproperf

This works(thanks MVied):

  • Run Registry Editor
  • Browse to \HKEY_USERS\S-1-5-21-(random numbers with dashes)\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts(whatever file extension is broken, i.e. '.jpg')\
  • Delete the folder called 'UserChoice'

I'm wondering why you are trying to open a jar file using Windows Explorer...change the properties...set it to run with java.exe....everything should be fine...and coming to the 200+ question...unless it is a virus or something, it should not behave in such a way...strange to see that happen....try opening other jars in a similar way...you'll get to know the problem and the eventual solution...

Maybe do you want to view the contents of the jar? Take a look to this page. Or try with what is written on this page if you want to execute the jar without the command shell.

EDIT:

The problem of windows explorer is described in this page and in this too.

  • That was what I was trying to do (thanks!) but I'm mostly interested in why a couple hundred `explorer.exe` processes were created when I initially tried. – BenCole Aug 30 '11 at 15:53
