Is there a shortcut to mute sound in Windows 7?

Solution 1:

Answer derived from @Randolf Richardson:

1) free utility called nircmd http://www.nirsoft.net/utils/nircmd.zip

2) create a shortcut: "C:\Michal\Code\Mute Sounds\nircmd.exe" mutesysvolume 2

3) set up shortcut key

EDIT / UPDATE: comment below is right / intention of the question is clear. Honestly I have no idea why did I answer this way :)

Solution 2:

It is also possible your keyboard has media functions built into it.

A lot of my function keys have media functions if I press them with the Fn key.

Solution 3:

windows + x contains an options to mute

and whole bunch of other options like:

1. brightness
2. mute
3. battery options
4. WiFi or connectivity
5. display or monitor or projector on off
6. sync services
7. presentation for office users

Solution 4:

You're probably pressing ctrl+s. That tends to be the default sound effects shortcut for most games. Since most people play WASD this tends to cause issues at some point.
