Standsrd User versus Administrator

Hello,

I am new to CCleaner and so obviously new to this forum, and I have a question:

Checking the FAQs I see that I should ideally run CCleaner as an admin (presumably the 'Run as administrator' option is sufficient), and reading the FAQ I see that there may be some files I cannot remove as a standard user. I noticed, however, that when I did run CCleaner as a standard user it came up with a whole host of registry problems which were simply not shown when I ran it as an administrator. Why is this? Particularly since it threw up a load of apparently 'unused' file extensions, many of which I recognise are associated with known and installed applications. Why would it show these?

Also, if I log in as me (standard user) and 'Run as administrator', will I get different results compared to logging in *as* the administrator and running it from there?

Hope somebody can help me out with an answer here as I don't want to cane my registry unnecessarily.

Regards,

Angus

Are you by chance on a XP machine? The run as admin in in reference to vista/7/8 UAC elevation not the category of users, nor the actual user, "Administrator"

can you show a screenshot of the 'unused file extensions'?

I've never seen CC reg cleaner show unused file extensions that really weren't unused.

also state your OS and CC versions.
