For the sake of this thread (possibly) helping others who also search for this stuff later as well, I didn't actually need to search/download the driver
Ultimately my mission was to partition that one drive which the people who made my computer did so Windows 7 could reside in a smaller amount of space (in C drive), while the virtual environment would operate multiple OS and test spaces in the other partitions; hopefully leaving the base OS (in C drive) relatively free from accumulating a whole lot of extra files over time.
So, when you're unsatisfied with the way the people who built your computer set it up on just the one drive, here's what I just did:
(Disclaimer: I'm new to all of this and not sure if this is the best way to go around it, but it's how I eventually got around my problem)
1. Right-click on 'Computer' from the 'Start' pearl to click on 'Manage'.
2. Click 'Disk Management' (found under 'Storage'), then right-click on C drive to click on 'Shrink Volume...'
3. Shrink it to half it's size (default).
4. Right click on the Unallocated partition to format, choose 'New Simple Volume...'
5. Fly through the wizard then re-install Windows 7 choosing the custom option and putting the new Windows 7 install on the newly formatted drive.
6. Next I just removed/cleaned C drive, and created it again at only 50GB's (could have made it smaller but didn't), then re-installed Windows 7 again on new (smaller) C drive.
7. Okay, off to install VMware on the new (larger) partition now... Hope this helped someone else.
If not, please reply with anything/everything done wrong; I'm really open to criticism for the sake of getting much better at this.
Cheers : )
