I wanted to share the freeware utilities I used for years from NirSoft that works somehow as the expensive commercial Network utilities sold by monster companies. The one I like and just used it today is the Wireless Network Watcher to view who is connecting to your router without logging in into your router.

one of the most useful windows utilities is Ccleaner

there are other software of course, but this is essential since windows is so slow when compared to linux, I left windows for good, it sucks, i switched to linux mint, i wish i did that long time ago. no anti virus, no need for software to speed up my pc, no crap, linux is heaven in the computers world :)
