i found some registry entries which are not detected by ccleaner 2.20.920.
the entries are found at: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\TypedPaths
(i use windows 7)
this key remembers typed url/ip's/network shares in windows explorer
in my case the key contains: 1 default key and 25 url keys (url1 - url2)
Windows Registry Editor Version 5.00[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\TypedPaths]"url1"="\\\\192.168.1.1""url2"="\\\\192.168.1.2"etc.."
would be nice is ccleaner could delete these.
