I have installed Windows 7 on Virtual box. I have installed virtual box guest additions. My host OS is Ubuntu 16.04
My Windows is running extremely slow. It is often hanging so much that poweroff is the only option. The .Net Framework 4.5 took forever to install. My anti virus programs are simply refusing to install.
It may be noted that I have allotted 6 GB RAM to Windows and my total RAM caapacity is 12GB.
