Windows 10 Saving Multiple Desktops

I haven't seen that either. I use my 2nd monitor for my Google Calendar or E-mail, and my 1st monitor for everything else. What you might consider is buying a 2nd PC if you want to go beyond 3 screens with each being dedicated to specific app or browser/app combo. Since it sound like you have 3 monitors each showing a different app or browser/app, you only need to get a 2nd PC with a dual-monitor card for the dedicated 4th and 5th apps. You can find used Dell Dimensions that are 8-10 years old with this setup for $150-$200 on ebay and most of those will run W10, [make certain they are not built prior to 2007, else you'll have hardware issues upgrading to W10], which you are running presumably on your current machine since you posted your question in the W10 forum. Then add 2 monitors, such as LCD, install your apps, and W10 will do the rest. You would then have 5 monitors showing 5 different apps every time you turn on your computers! If you went with 17" LCD monitors those are $100 new on Tiger Direct or cheaper if you shop around. For $350-$400 you could do this setup and get what you want using additional hardware. Sorry there isn't a way to use the virtual desktop in W10 to do this.

Best of luck,
