On Windows Vista & 7, when you select a file and press F2, only the file name is automatically selected without spanning the extension. Then you can write the new file name and hit enter. It is a useful feature as you don't have to select the file name apart from the extension by hand. On the other hand, Windows XP behaves old fashioned by selecting both file name and extension. Is it possible to do this by tweaking the registry of XP?
Note: Please do not propose to hide extensions for known file types.
2Can you elaborate on that? How does it work, what does it do, how would it do specifically what OP wants? – bertieb – 2015-09-22T08:50:12.463
