I believe I saw similar complaint in MSDN forum. Check Windows 10 forum there and see if that has been reported.

>Sense MS updated my machine to WIn10, and few new features have appeared (or disappeared).

>The first, and most ignoring, is the that vanishing mouse and cursor. On random occasions, the mouse pointer will just disappear. Its there, just invisible. but if I move the invisible mouse pointer to the far right side of the screen, it will reappear. Also, sometimes while I am type something, in any application, the cursor will disappear. Once again, if I move the mouse to the far right, the cursor will reappear. I have searched the web but have not found similar complainants.

>Also, on occasions, the cursor will jump to another application. Forcing me to re-establish the prior application and re-type what I was working on. Is this a feature? This generally occurs when a notification arrives, and a pop-up is displayed. The associated application take control. Even while I have been writing this message, 4 times I have had to click on the this web page to re-establish focus and re-type something.

>The next ignorant is the missing features. I guess MS felt that people did not need a History button, or a Home button, or the ability to drag and drop a link to make a short-cut to a web page anymore. Even if I go to Google to search for something, sometimes (most of time), the Edge browser takes control and does the search instead. And what happened to the Menu bar and Status bar? I downloaded and started using Chrome browsers.

>There are many more missing features that were there in Win 7 and 8.1 that are now gone. Dummying down the products does not make it better, just harder to accomplish what we are use to doing. Sure, removing a lot of the features and ad-ons make the products load faster, but also prevent the user from accomplishing their expected duties too. But, I guess the little children at MS who are used to design the OS and UI don't see why a person would need these features, as long as they can get to the latest games and social-media web sites.

>Enough for now. Can't wait to see what new lack of features will come in the future.
