Mycomputer crashed and I lost everything. Got a new one and my brother was able to save some of my folders off my old hard drives. Is there any way someone could get into this computer and get my profile back for WAW?? I have the folders and profile on here (I hope). Just can't figure how to go further. Thanks.

Trying to remember how the profiles were stored on WAW.
Are you using the stand alone version or the steam version?

If the stand alone, just install the game as new. create a temp profile name. Search for that name, should be somewhere like /electronic arts/world at war/ profiles.
copy the old files there.

I have to looke at my old computer to be sure. I know I did it in the past.

should be here somewhere - remember it is a hidden folder!

C:\Documents and Settings\[USERNAME]\Local Settings\Application Data\Activision\CoDWaW

Gump this is this is the Windows 7 place = C:\Users\yourname\AppData\Local\Activision\CoDWaW\players\profiles

I have windows 10 on this one. Will that make a difference?

Not offhand - I've found windows 7 and 10 typically used the same file layout
