Hello,
I need to start Boinc client without any GUI, only run process in background. I've searched in wiki, FAQ, but i didn't see anything.

I'm runing Windows machines. ¿Is there any way to do it?

Thanks and greetings.

Not all projects support BOINC running as a service, and many will fail to make use of any installed GPU due to the way Windows handles drivers in service mode vs. "normal" mode.
Another way (and a slightly messy way):
Start in the normal (GUI) manner, exit the GUI, but when presented with the "Stop all processing" nag window untick the "stop processing on exit" box.

However, on my old headless windows machine, once installed I was able to run without the GUI, and BOINC was not running as a service, sorry I can't remember how and since that machine is now running Linux I can't get at it to see how.

When you want to run BOINC as not a service so you can use your GPU, you can just start the client (boinc.exe) via a desktop shortcut: To automate that when starting Windows, do:
- right click an open space on the desktop
- New
- Shortcut
- Browse to the BOINC programs directory, e.g. C:\Program Files\BOINC and choose boinc.exe
- add behind it on the line --detach_console, make sure it falls outside the quotation marks if these are around the path.
-- the path should look like this: <code>"C:\Program Files\BOINC\boinc.exe" --detach_console</code> with the quotation marks there because of the space in the path. --detach_console closes the Windows command-line window but leaves BOINC running.
- click Next
- fill in a name for your link, e.g. BOINC client
- click Finish

You can add this link to your C:\Users\{username}AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup directory to have it start up at Windows login.
Logging off will stop these calculations again.
