Ok if you encounter a freshly installed Windows 7 client and are not using dynamic memory on hyper-V even though you have already set it in options that it should – try upgrading the Integration Services.
Just go to actions then choose “Insert Integrations Services Setup Disk”.
Then when autoplay comes, just run.
Click ok on UAC
While installing, grab a beer and walk away.
Restart when appropriate.
Will install some updates….
After booting.. WHALAHH!
All clients are now running dynamic memory!
This post is dedicated to the one that called me earlier while I am at work asking about this so I figured, lets just post this overdue draft! Good luck tomorrow!
