How to quickly enable/disable proxy in browsers, skype, etc.?

Question

Computer networks

Often you have to switch between Internet networks. One network works through a proxy, the other - without a proxy.
How can you quickly disable / enable proxies in all programs at once, so that you do not have to go into the settings of Skype, Chrome, FileZilla, etc. every time?

Answer 1

The setting itself is stored in the ProxyEnabled setting under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings. A value of 1 enables the proxy server, and a value of 0 disables it. In such cases, it's easier to create a command line script to quickly enable/disable the proxy server.
eppon file. cmd (enable proxy):
reg add "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /t REG_DWORD /d 1 /f
iepoff. cmd (disable proxy):
reg add "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /t REG_DWORD /d 0 /f

Answer 2

There is a special utility from Microsoft, but if the proxy is manually configured in the program, this will not help.
C:\WINDOWS\system32>proxycfg.exe /?
Default Proxy Configuration Tool Microsoft (R) WinHTTP

Usage:
proxycfg -? : view help
proxycfg : view current WinHTTP proxy settings
proxycfg [-d] [-p <servername> [<bypass list>]]
-d : set direct access
-p : set proxy server and optional bypass list
proxycfg -u : import settings proxy from current
manually configured Microsoft Internet Explorer settings (in HKCU)
