Progam to transfer selected keys from old registry file to .reg file?

Hi there,

due to some complete mishap, I was forced to reinstall Windows XP. Before doing so, I did a system backup, so I could restore all files. The problem is the registry. Due to the new install, many applications will not report as installed and request that I install them anew. But I got a copy of the old registry file (system32\config\software) in the backup. Is there any program that would allow me to edit this file and export those keys I need to a .reg file?

You are asking for more trouble... You should have created an image of the entire hard drive, and restored that image to a "clean" formatted drive. You could spend hours and days editing the registry, but even this wouldn't guarantee success
