Location of Registry Backup File

FAQ on resporation of registry backups states that th .reg file is locatead in the "My documents" folder by default. A file with this extension is not to be found in "my Documents". However I do find a .reg file in the c:\programs\CCleaner folder with a file date which approximates the date I believe I made a registry backup and then "Cleaned my registry". THe file name is cc_20110405_143243.reg. Subsequent to the cleaning I'm now experiencing extremetly slow start ups. I want to restore the registry. Would this be the file I would right click "Merge" on to restore the registry?

Thanks

Yes.

Thanks!
