RDP Causes High CPU

[ITGURU]

I have a Windows 8.1 machine, 64 bit with 16GB ram and an SSD and is all up to date with drivers etc.

If I use the machine generally there are no issues with CPU usage and remains low.

 

However, as soon as I connect to work via SSTP VPN and load Remote desktop on to my work PC, after a period of time, CPU usage rockets up as seen in the attachment below. The CPU usage shown is that on the client, not the remote PC.

 

If I close down the remote session, CPU doesn't drop off, the only way to get it back to normal is to reboot, unless next time I use remote desktop.

Both the laptop and remote PC have had new windows installs during the period of this issue,

 

Anyone shed any light on this or ideas as it's a pain!

Thanks
