Does your VPS feel a bit slow? There could be a few factors at play here. First thing is to check the task manager within the VPS to make sure you're not using 100% usage of everything. If it is, try to close out apps that aren't being used. If everything that's opened, needs to stay open we advise upgrading your VPS to the appropriate needs.
Otherwise, you should install the Virtio drivers. Each Windows VPS runs on a Virtio drive setup. To take advantage of the speed of Virtio, you need to install the ISO image onto your VPS. Here is the direct download link, copy and paste it into your VPS browser. https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/stable-virtio/virtio-win.iso
