I have a new Windows 10 laptop. I just saw three instances of "pageant putty authentication agent" in my task bar inside one "box"/widget. When I opened the box, only one instance remained.

I did not install putty or pagent. So, why is this running on my system ? If it need not run, then how do I disable it ?

Thanks !

  • If you did not install putty or any program that ships with Putty (e.g. TortoiseGIT) it looks like the laptop was not new.

  • @Robert - I had reinstalled the OS recently. But, I also installed source tree and git kraken, besides other developer tools. I now wonder to to find out which app installed pagent.

Noticed this on my laptop too recently and saw it's under Source Tree.

Very late, but just in case someone else runs into this too.
