I have several virtual machines Windows 7 x64 and x86 sp1 without additional applications.
Install both dvd microsoft, both virtualization of the physical machine.
The machines work well and quickly until active Windows Update.
Then the processor of the virtual machine goes to 100% and to install also a simple upgrade takes several hours.
If you stop the windows service, the processor returns to 0.
Tested on different hardware, both Player and pro workstations, same problem.
Else . If I virtualize a physical machine with all the microsoft update already installed, these are not present in the virtual machine.
Some idea ?
