Can I still use an external mouse, and what about upgrade to windows 8.1

Yes, you can use an external mouse via the USB ports. Yes, it will upgrade to Windows 8.1. As I recall Microsoft is making v8.1 a free upgrade.

yes you can connect an external mouse. You can even use a bluetooth enabled external mouse; this eliminates the need for the usb plug.

A mouse (any mouse) works with any system. It's just a pointing device. So yes it works with 8.1 and any other operating system on any computer.

These are the best mouses ever! I have used them since Win98 also. I am presently using one on a Win 8.1 computer and my husband has one for his Win 8.1 computer. Nothing to install. Just plug it in. But if you want more setting choices you can either use the disc or just find them online. Takes a second. But it will still work fine without even installing anything.

Yes you can. Depending on your USB device it will support IR, RF, or Bluetooth mice.

Yes, this mouse will work with Windows 8. And since it is a Microsoft product, you will get updated drivers via Windows Update.

Yes, I am currently using windows 8, and I have full functionality of the mouse.

The Logitech software does not work with Win 8.1. You can use most functions but you will not be able to use the zoom button or customize any keys. You will also not be able to customize your mouse. Some people are having other problems with basic typing as well. Try not to upgrade to 8.1 if you can stand it.

This mouse will work with Windows 8, but does not support very many touch gestures. There is a newer touch mouse from Logitech that was designed specifically to take advantage of the new features in Windows 8. Take a look here: Logitech Touch Mouse T620 with Full Touch Surface for Windows 8 - Graphite

I would not recommend it for windows 8, only get a mouse that says it IS for windows 8. Otherwise, there seems to be a lot of trouble with the mouse causing problems. But for any other system, it does work fine. My only issue is that I damaged my wrist a long time ago and need a mouse that does not require repetitive movements. You can also use this mouse on just about any surface and it is easy to use and install and will connect up with other wireless logitech devices so you only need one wireless plug plugged in. NICE!!) You may need to go to Logitech to get the download to connect all devices that are Logitech, but this is a really nice feature and frees up your usb ports.

I'm using Razer Synapse 2.0 with Windows 8.1 just fine, with the exception that my mouse has a hardware issue (as I stated in my initial review of the product).

no but any mouse will do.. I wish I had gotten a touch screen because windows 8 is kind of a pain to navigate.

It works great with Windows 8.1 64bit. I custom build my system. I tried to use the mouse in the past, and I could never get it to work. I believe I finally figured that using usb wireless adapters didn't work. I bought a high end Pci express wireless network adapter with 3 antennas' and it works awesome. The drivers from Hp website and I haven't had a problem. It is a life saver for freeing up a usb slot.

yes, it is on my system. most usb ports are backward compatible. As an aside - both of my mouses (mice?) are wireless and I have them both plugged in at that same time and just grab which one I want to use.

I have the OS Win7, so I don't know if this specific mouse is compatible with Win8. But generally all mouses are compatible with all types of OS, so I doubt that there will be any problem with it.

Very much so. I have 8.1 and the Windows button on the mouse works pretty well with it, though it is limited to bringing up the apps screen. I think you may adjust it, but I have not needed to do so.
