Hi there @yking,

If you only power off your Droplet you will still be charged the usual price.

What you could do is store your data on a block storage for example and then destroy your Droplet whenever you don’t need it.

As of the time being DigitalOcean does not have native support for Windows OS on Droplets, for more information I recommend checking out this answer here:

Unfortunately at this time, we do not have native support for Windows OSs on Droplets. You may be able to achieve this however by creating your own custom Windows ISO image and then using that when creating your Droplet.

Currently, DigitalOcean only allows the deployment of Linux based OS’s.

NOTE: This is not natively supported on the platform (choosing a Windows OS when you deploy your droplet).

We’d recommend that you add your vote to the Windows Server idea on our Product Ideas Board as well as comment on your use-case there so that our teams can better understand your needs.

Hope that helps!
