Registry "Find and Replace"

Hi all, I have recently transferred my Windows 7 Username Profile back to the default "C:" from "E:" partition, then I formatted the E:, all good. Most programs are working fine, then I noticed MSOffice2013 Outlook was still looking for the data file on E: and would not load. in the meantime, I had installed Win10Pro on E: as a dual boot.

Anyway, not confusing the issue, I have discovered most of the registry file is still referring to programs/data on E: when it should be C:. I figured I would change the registry entries to reflect that and the W7 Registry Editor is a very tedious procedure to achieve this simple find and replace.

Is there another editor available I could use, the file is too big for Note Pad (++)?

Thank you

Thank you Snick, I did do that but couldn't figure out how to save the file.
