Is there a way to enable AMD-V virtualization in Windows 7 Home Premium (SP1) without going into the BIOS or using UEFI?
Background:
I have an older Toshiba Satellite C875D-S7225 laptop that I purchased new in 2012. It came with Windows 7 Home Premium installed. Starting in 2015, I began using a programming environment called SAS University Edition running in a Linux virtual machine. The virtual machine was run under VMWare. Everything was running fine for several years even after repeatedly installing newer versions of the software.
I recently "upgraded" my laptop to Windows 10. My SAS University Edition programming environment ceased to work. Whenever I would start VMWare, I would get the message "This host supports AMD-V, but AMD-V is disabled." I then tried Oracle Virtual Box but got essentially the same message.
A bit of research turned up that the way to enable AMD-V virtualization is either through the BIOS or through UEFI. My laptop is a pre-UEFI version, so, as far as I can determine, UEFI is not an option. I tried going through the BIOS, but there is no such option under the BIOS setup. I upgraded the BIOS to the most recent available version (v 6.10), but there is still no option to enable AMD-V, and, believe me, I have looked through every possible option/combination of options in the BIOS set up.
I then did a recover back to Windows 7 hoping that whatever turned off AMD-V during the Windows 7 to 10 upgrade process would be reversed. No such luck. Windows 7 is back up and running, but I'm still getting the "This host supports AMD-V, but AMD-V is disabled" message.
I then popped out the CMOS battery hoping to flush the NVRAM. If my SAS University Edition worked before, without my ever having messed with the AMD-V setting, then surely the default setting must be AMD-V enabled and flushing the NVRAM would presumably re-enable that default. Apparently not. I believe I flushed the NVRAM correctly because I had to re-set the system date and time, but I'm still getting the "This host supports AMD-V, but AMD-V is disabled" message.
I've spent a lot of time on the phone with Dynabook (Toshiba's support provider), but they have been unable to help me.
I've downloaded a utility from AMD, amdvhyperv.exe, but all it does is to confirm that AMD-V is not enabled. I've also downloaded Microsoft's Hardware Assisted Virtualization Tool (havdetectiontool.exe), but again, it just confirms that AMD-V is not enabled.
So, my question is: Is there a way to enable AMD-V in Windows 7 Home Premium without going through the BIOS or UEFI?
