Middle click to scroll in Windows 10.

Hi Steven. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Moderator here to help you.

When did mouse last work correctly? What has changed since then? Is there a System Restore point to roll back to before then? http://home.bt.com/tech-gadgets/computing/how-t...

Change the batteries if wireless, try another USB port, reset mouse from button on bottom if available - or search Google for specific steps how to reset your mouse.

Try the mouse in another PC to isolate if it's the mouse or Windows causing this.

Try another mouse in this PC to confirm if Windows is the problem.

For mouse lagging or freezing issues see https://www.thewindowsclub.com/mouse-pointer-la...

Access the Device Manager reached by right clicking the Start button, choose the Mouse, then Driver tab. First try Update this Driver > Automatically, then Roll Back if available. If not choose Uninstall button, restart PC using keyboard to Ctrl Alt Del, on blue screen tab to Power Icon in bottom right, press Enter, arrow down to Restart, press Enter to restart to reinstall the driver.

Is there mouse software installed in Settings > Apps > Apps & Features? Uninstall it to see if the problem stops. This is unneeded bloatware.

Adjust the mouse settings in Settings > Devices > Mouse, checking all settings including the Additonal Mouse Options box - check Settings on all tabs.

Report back all results for possible other things to try.

To check if Windows is causing this you can also go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files. Then continue with the other steps to go over your install most thoroughly.

Update your drivers from the PC maker's Support Downloads web page, using the full model number, Serial Number or Dell Service Tag on sticker. Compare the latest drivers available for download with the ones presently installed in Device Manager reached by right clicking the Start Menu. Make sure you have the latest BIOS or UEFI firmware, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

If this was caused by Windows Update(s) then you can check which were installed at Settings>Update & Security>Windows Update under Installed Updates, then uninstall them from the link there, and hide with the Hide Updates tool downloaded from here: http://download.microsoft.com/download/f/2/2/f2...

You can also use System Restore to get before the problem began, then check for Updates with the Hide Update tool and hide them: http://home.bt.com/tech-gadgets/computing/how-t...

If nothing else helps you can run a Repair Install by installing the Media Creation Tool and choosing from it to Upgrade Now. This reinstalls Windows in about an hour while saving your files, apps and most settings, solves many problems while also bringing it up to the latest version which you need anyway and by the most stable method.

Try my mouse - Logitech M330. Middle-click-to-scroll works fine, although I don't use it. Stuck in my old habits, I guess.

When I click on the scroll wheel, the mouse pointer turns into a double-headed arrow. Then I can move the mouse to scroll.
