Multiple questions

[meridius7]

I have been using CCleaner Free for years but have some questions:

1. In the main GUI Windows Log Files are normally ticked to be analysed/deleted. Why? Surely they are important to keep in Windows.

2. In the same menu but in Applications > Windows there is an option for running CCleaner on RegEdit. What does this actually do?

3. If I fix registry items can I have a problem with restore points in Windows? Is it completely safe to fix all?

4. Where does Tools > Startup feed off? I thought it was from msconfig > Start-up but is it a combination of this and some items from services.msc?

5. In Options > Cookies can I safely delete them all?

6. In Options > Advanced can I safely untick "Only delete files in Windows Temp folders older than 24 hours". Why should these files be kept at all?

Many thanks for any advice at this stage.

Perhaps start here first, and then if you still have questions ask them:
https://www.ccleaner.com/docs

Can nobody answer my questions quickly or do I have to spend hours going through the documentation?

1. log files by their very nature just log events.  if you want to see the history of an event, then Yes, keep your log files.  all I can say is that in 30 years of professionally using PC's I have needed to look at a log file maybe 3 times.  so, don't run CC if you are troubleshooting.

2. I've stayed on v5.40 so don'y know about that new feature - sounds wanky to me.

3. you run the potential to restore a 'broken' registry if the restore point has a snapshot of such a registry.  cleaning the registry is always potentially unsafe not matyter how small and simply not needed these days except in removing gremlins.

4. it is msconfig, with a bit of 
    %appdata%\Microsoft\Windows\Start Menu\Programs\Startup and
    %programdata%\Microsoft\Windows\Start Menu\Programs\Startup and
    for 32bit
       HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Run
       HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\RunOnce
   and for 64bit
       HKLM:\Software\Microsoft\Windows\CurrentVersion\Run,
       HKLM:\Software\Microsoft\Windows\CurrentVersion\RunOnce, HKCU:\Software\Microsoft\Window\CurrentVersion\Run, 
       HKCU:\Software\Microsoft\Windows\CurrentVersion\RunOnce

5. all depends if you want to keep what the cookies are saving

6. I've never had those options ticked.  again, it's all down to personal preferences - do you what to delete everything or just everything but the last 24 hours?

Applications > Windows > RegEdit

All that does is delete the MRU ("Recent Location") in RegEdit where you were last viewing a key. It doesn't harm anything.
