Software for checking proxy on Win?

Question

Windows

Hello. There is a list of 20-30 proxies, you need to check the availability of these proxies often.
At the moment, I check through the plug-in mazila, but it's not very convenient.
Tell me, maybe someone knows, software under win, checking proxies? Preferably with authorization log pass ip port
