No ProSet tabs after installing Intel drivers for PRO1000/PT Server Adapter

I rebuilt my Windows 7 Professional box this week.  It was time, and installing with SP1 slipstreamed allowed me not to have to load a third party AHCI driver for my 6Gb/s SATA controller.  Everything was fine until I realised my network speed was a little slow.  I hadn't installed Intel's driver and ProSet yet, so I downloaded the most recent.  After installation, the Advanced tab was gone, but no ProSet tabs.  Uninstall the driver, the card would get re detected, Advanced tab would return.  Reinstall Intel driver, Advanced tab gone, no ProSet tabs.  Updated to latest driver from Windows Update.  Same thing.  This went on for a couple of days with slight variations.  Here's what I did to ultimately get the Intel drivers and ProSet installed and working:

1. Uninstall the nic via Device Manager.  Check the "Delete driver" box.
2. Follow this to disable automatic driver installation. (That procedure only works on Win 7 Pro+)
3. Either re-scan for devices in Device Manager, or reboot your system. (I chose to reboot)
4. Once restarted, verify that the nic shows up under "Unknown Devices" as an "Ethernet Controler".
5. Revert the change you made in gpedit so you can install the correct driver now.
6. Install the appropriate version of Intel's drivers/utilities for your card.

You should now have all of the tabs for VLANs, Teaming, Link Speed, and Advanced.

Hope I save someone out there some time.

** ADDENDUM **

I upgraded the Intel drivers recently, and after that I was back to my original issue.  Turns out I also needed to uninstall VirtualBox to get things back to working.

Actually, if you do not install Host-Only networking in Virtualbox, the problem doesn't appear.

Ubuntu 12.04 LTS in Virtualbox SLOOOOOWWWWWW

I've been trying to install Ubuntu 12.04 LTS in Virtualbox 4.2.4 for about a week now.  It would install eventually, but it was slow to do so, and almost unbearable to actually try to use.  Someone mentioned that if you had multiple CPUs configured for the VM, change it to one.  I had only one CPU assigned, so I changed it to two, and restarted my install.  It completed in less than five minutes.  Moral, if your having performance issues installing or using Ubuntu 12.04 LTS, make sure you're using more than one CPU.
