After fresh instal Windows 7 or 8, same things in registry cleaner -
CC v.2, v.3 & now v.4, why?! Screenshots attach.
Because the .NET Framework v1.x is outdated and I believe fully superceeded by versions 2.x-4.5
I've gotten those before for .NET v1.x and just let CCleaner dispatch them without issue.
They occur after every .net update they actually are no longer needed as the version of .net has changed (you may think they come back, but they're different version numbers)
are you still using p2phost?
I'm not sure, how do I know if it is active? Peer-to-peer (P2P)? / People Near Me? Is not shown in processes Task Manager. I search in C/Windows 'p2phost' and result is 0. Windows 8 X86, windows firewall disable, and firewall KIS (Kaspersky) 2013 active, homegroup network disable, public network active set.
Invalid Firewall Rules come up when there are firewall exceptions that point to programs that no longer exist where the pointer leads.
