Enabled TPM and HAV (all Virtualization) on Latitude E6420 -> but Windows 7 HAV detection reports not enabled
Hi
Win 7 HAV Detection tool indicated my Latitude does not have Virtualization enabled
I went to BIOS settings and changed them to enabled for all 3 Virtualization options, as well as for TPM
(One of the Virtualization settings indicated TPM must be enabled)
I then selected TPM activate and rebooted the machine
However, HAV Tool still says 'Not enabled'
Any ideas?

Dell does not answer questions for the

Hyper V VIRTUALIZATION now requires SLAT instructions which means CORE I3 I5 I7 minimum. SLAT (Second Level Address Translation) is a feature of the CPU. It is called “Rapid Virtualization Indexing (RVI)”, and has been called Extended Page Tables (EPT) by Intel and Nested Page Tables (NPT) by AMD. You can use Wikipedia to look up Intel Nehalem and AMD NPT:

Here's a blog post from Ben Armstrong that should describe how to get it installed:

The key is to uninstall the update that installs WVPC, then it should work.
