Recovering reg key from CC backup

Hello, Please, I deleted manually a key in the windows registry and I remembered me that I have a .REC of CCLEANER.......I´d like to know if I can open this file and see all keys of regedit and copy or enter manuallly with the key that I deleted and should be saved in .REC.

I opened the .REC, but I didn´t see all keys of windows. I thought that it should have. It´s a suggestion too.

I was deleting a key of GBPSV (from a security app of a bank) and deleted GBPSVC (from windows analysis or monitoring) too.

Do you mean a .reg file? I think that .rec files are associated with video recording. The CC .reg file only contains entries that have been selected to be cleaned by CC, so will not contain entries deleted by any other method. It isn't a full registry backup, so you are probably out of luck.

If it's something you deleted manually (not while using CCleaner's registry cleaner), and need to undo the damage try a System Restore Point which can restore the registry.
