Haha..got you there....its a windows 10 and I added startallback (https://startisback.com) for that sweet windows 7 logo only. I hate that boxy logo design of win 10. It's a msi prestige 15 11th gen i7 with 16gb ram. Video cards are Intel Iris Xe and Nvidia 1650. The intel graphics tends to do better when selected as primary for vegas pro since it runs parallel with nvidia and can decode faster that way. Source: almost 2 years ago

StartAllBack, startisback.com, 30-day trial and $4.99 after that. I wasn't totally satisficed with it. When Start11 added the Windows 10 start menu, I went back to it. Source: over 2 years ago
