Change Registry To Make Changes Permanent

I use CCleaner everyday and it removes all TMP files, which is what I want.However, it also REMOVES the settings I make with "TweakUI" to change "AUTOLOGON", to "LOGON AUTOMATICALLY AT SYSTEM STARTUP", and "VIEW / THUMBNAILS" to "VIEW / DETAILS". Using Google, I have found that these changes are made to a TMP file. When I use CCleaner, it removes the TMP files that have the changes that I want.I have Googled for hours and can not find the answer. I did find mention that the changes I make are saved to "TMP" files and therefore, CCleaner is removing my changes. It mentioned that the REGISTRY could be changed to make my changes permanent, but the site did not tell me how to do it.Can anyone tell me how to modify REGISTRY to make my changes permanent? I want to keep "LOGON AUTOMATICALLY AT SYSTEM STARTUP" and to have all files shown as "DETAILS"
