Windows 10: Do I need Defender?

Excellent !!!
*Thumbs

Go slow when you install the software - install one and see how the machine and program operate. If all is well, do another program.

Try to resist the temptation to install HW drivers (it took me about 3 months on Win8.1 to break that habit *Wink). Windows does a very good job ... always check Dev Mgr and only look for drivers IF there are issues. The latest and greatest aren't always better.

 

So far, so good. One issue that has been present in both installs is my Microsoft Intellimouse. When booting into Windows or if the PC sleeps, it's not active until I unplug / plugin back into the USB port. Once up on the desktop it seems OK. Don't know about that one! *Confused

 

Probably a totally late suggestion by now, but I just read this thread...

There is a Removal tool available from bleeping computer so maybe it'd work..

I've always had problems with IntelliPoint and Intellitype - for a while (years ago) no version solved the jittering pointer or repeating keys, so I just removed the software. I didn't have any hot-keys setup and the mouse buttons were default. The standard Mouse and Keyboard drivers worked fine for my modest needs. The built in keys (defined by the keyboard, not software) also worked fine.

So if you don't use the special functions in the software, you don't need it and it can be uninstalled.

A bit of Googling tells me this is not only an issue on your machine, nut I didn't find anything that was the silver bullet. I didn't find anything in a search for Intellimouse at Microsoft Community.

Did this work on previous versions of Windows (which one? Win7 or Win8.1)

You might use the Windows Feedback app (MS account required) to report it to MS,

Side note: If you uninstall the software, Windows Update (WU) will probably download it again, when the actual Initellimouse install dialog is presented, cancel that install and WU thinks everything is up-to-date *Wink
