Whenever I want to create a new txt-file from the context menu (right click) in Windows 7, I get a file with xyz.TXT instead of xyz.txt. How can I change this (no, I don't have caps lock on)?

I already searched for a regedit-entry and under HKEY_CLASSES_ROOT I find an entry called .TXT. When I rename it to .txt and reboot it works.

However, after some time I have capital letters again.

You may use regmon or procmon tool from SysInternals family to find out which process is modifying this registry key, this will give you some clues to the reason of the problem. – Jack Shainsky May 5 '11 at 9:30
@Jack Shainsky Thanks. How do I use it? I set up a filter like this: Path contains HKEY_CLASSES_ROOT then Include. Will this be sufficient? – Torsten May 6 '11 at 12:54
regmon uses a shortcut for HKEY_CLASSES_ROOT, so you should set the filter for HKCR. I would set it for HKCR\.txt for getting only the messages that you're interested in. – Jack Shainsky May 8 '11 at 10:28
I have this as well, do you happen to use Notepad++? – Qosmo Feb 2 at 19:10
@Qosmo No, I don't have it installed and I think I didn't install it ever on the machine I'm having trouble with. – Torsten Feb 8 at 12:29
