[Q] HD2 Windows drivers from scratch topic

Cliffs Notes Version:
On a clean Windows 7 computer what do I need to install to get my HD2 to be recognized properly so I can flash some new roms? Drivers? ADB? HTC Sync? All of the Above?

Details:
I have had my HD2 running Android builds for a long time now but haven't flashed a new rom in over a year. I just broke my GS3 and need to dust off the old HD2 to tide me over until I get a new phone. I am having issues getting my computer to recognize the HD2 properly however so I can flash new roms. Both of my computers have had drivers installed to get the GS3 and the Nexus 7 connected to them since and I think the drivers are getting all messed up. I am going to go use a computer that has had no drivers of any kind on it to get it to connect but I am still unsure of what I need to install to get it connected. Drivers? ADB? HTC Sync? All of the above? The HD2 Toolkit has a button for downloading drivers but the link is broken and everything I download since seems to not work.

Thanks for any help or direction!
