I let Revo Uninstaller's junk file cleaner delete "system.old" and "software.old" in C:\Windows\System32\config folder. I thought they would be recreated at some point. I have "software.blues" and "system.blues", they're (very) slightly smaller in size. Also, in properties, the "system" and "software" files were modified today.....the created date is 2009, the time the PC/HDD was made(?), I bought & set it up Aug. 4, 2010.

Running W 7 SP1 x64 - Thanks in advance, best regards,
-Dale

I seem to be dense this morning...but...what is the problem?  What is it you want to know or correct?

 

FWIW:  Files with the .old extension....are backup files or files which have been renamed by a user.  They are not pertinent at all to the proper operation of Windows.

If you are asking about Revo's program and its workings...this topic needs to be moved to a different forum.

Dale,

 

Did you ever restore the registry from the recovery environment, or did you bring your PC to a repair shop to get it repaired? I'm guessing that long ago the registry got corrupted, and you restored it from backups in the RegBack folder. Depending on the method you used, you may have renamed some of the files to have a .old extension. Below is a quote from Microsoft's TechNet forums, demonstrating how to restore the registry:

Reset the registry

===================

Cd  c:\windows\system32\config

Ren  default  default.old

Ren  sam  sam.old

Ren  security  security.old

Ren  software  software.old

Ren  system  system.old

Copy  c:\windows\system32\config\regback\default.old  default

Copy  c:\windows\system32\config\regback\sam.old  sam

Copy  c:\windows\system32\config\regback\security.old  security

Copy  c:\windows\system32\config\regback\software.old  software

Copy  c:\windows\system32\config\regback\system.old  system

Thanks for the link hamluis. A virus wiped this PC out in Oct. 2013. I did ONE factory restore, besides that it's never been out of this room. I'm surprised it runs so well. (bwv848) - In c:\windows\system32\config my PC don't have "software.old" or "system.old" (#2) files. They're the only #2 I deleted. In c:\windows\System32\config\RegBack there's #5 files (no .old), I never touch them. All I need to know: Did I mess up? Do I need "software and system.old"?

 

Everything is running good, no errors. I hope I'm not confusing anyone, I'm dyslectic and slow to learn.

They are not needed.  Typically, they are created by a Windows install over another install and they serve no purpose other than allowing users afraid to delete...to keep them on hand.

Thanks very much. I know all, seems to me, .old files in W 9x were safe to delete. I went from W 98 SE, to Vista then W 7, never had XP. I didn't keep Vista ....got W 7 within several months. I thank you kindly, have a good day.

Wanted to say thanks Louis. You have a nice image here, I saved it. I appreciate the help. I should have known I didn't need those files, been using a PC since W 98. Happy holidays,

-Dale
