Windows 10: mouse lag/stutter makes it almost impossible to work

A couple of months ago, I notice that my wireless mouse was starting to hesitate and lag. Usually, I could move the dongle to a different USB port and that would solve the issue for a while. However, a couple of days ago, it started getting really bad. Now it doesn't matter what port it is in. I have tried: updating/reinstalling all mouse drivers. Nope. I even bought a new Microsoft mouse with a big "Windows 10 ready" sticker on it. Nope. Other mice have the same issue, too. Not sure what to do next. Basically, my computer is a 25-lb paperweight if I can't get my mouse working properly. I did look at some threads on this forum with folks who had similar issues and tried a few things there (disabling Realtek as startup was one idea. Another suggesting to turn off the "scroll when hovering over an inactive window" in settings.), but none of those worked, either.

I've been using Windows 10 ever since it was released last summer, so I don't know why this problem is appearing now. Seems like something that would crop up on a brand new build.

Cumulative Update for Windows 10 for x64-based Systems KB3097617

This particular update causes my mouse to lag/stutter. It makes everything in general seem slow/laggy.

Oh yeah....and a Microsoft bulletin suggested the "sfc/scannow" approach. It didn't find anything wrong.

 

I really don't know if this will solve your problem since it just started a couple months ago but my mouse was doing the same thing. What fixed it for me was to put the mouse dongle on the end of a USB extension cable and moving the dongle away from the computer case. The lag and jitter completely went away. My extension cable was about 18" long. I read it has something to do with the frequency of the CPU interfering with the frequency mouse. Most mice run at 2.4Ghz, some run at 5Ghz. If you can find one that runs at 5Ghz, that should also solve the problem.

I hesitated commenting on this thread because my problem started right after I built my computer. If yours just started, you might want to think twice before you spend money on an extension cable or new mouse.

 

Thanks for the suggestion. It does seem unlikely as my computer is a couple of years old now, but who knows?
