Since a few days, any software installation on my Windows 7 computer is very slow. This is on a Windows 7 64bit setup of just a few weeks old (new computer).
I've waited for over an hour for VirtualBox to install. Same for AVG AntiVirus and some other programs. Cancelling the installation equally takes a very long time. Effectively, I've had to kill the installation processes.
Process Explorer doesn't show any significant activity of any kind and everything else still seems to be working fine and fast. Any ideas of what might be wrong?
