Question: Will this keyboard and mouse work with Windows 8.1 64?
Document: Overall, the keyboard- mouse words as advertised. In a windows 8.1 machine, there was essentially no setup - the OS recognized both and we were good to go. My only reservation is that on the keyboard: the function keys on the keyboard are small, and some of the other keys (e.g. delete) are in places that were not in my previous Logitech-style keyboards.Note:  the mouse battery is tricky to find -push down on top of small "door" - I used a screwdriver and slightly cracked it.One negative:  in our case, the battery goes after around 2 months.
had a BACKWARD slash in it; however, he said the directions were WRONG, that it was a forward slash. SERIOUSLY? then he verifies that the download option is only for a windows 7 system. he has me go to a DIFFERENT product altogether to get a vista option. ARE  YOU KIDING ME?? then THAT doesnt even work!I'm taking this HEADACHE of a Microsoft back tomorrow!1) Freaking lousy ass picture directions,2) Url's that are INCORRECT,3) Packing says 'Windows Vista' compatible; however website says otherwise.I'll stick with my keyboard/mouse combo that I already have.
I purchased this Microsoft Wireless Keyboard mouse combo to help eliminate some wires from my desk setup. I chose Microsoft because I have had good luck with their peripherals in the past.Pros:* Works with my IOGEAR KVM* Single USB Transmitter that connects to both the keyboard and the mouse (Freed up a USB port on my KVM for something else.). * Mouse works on just about all surfaces. * Keyboard has Customisable buttons. * Drivers automatically install on Windows 7 and 8. * Low Battery warning light.
It works well with windows 7 and 8. The mouse eats batteries pretty frequently, but the blue laser does track nicely on reflective surfaces, so its a decent trade off. The only thing I wish it had that it doesn't is status lights for caps lock and num lock. Otherwise, its a great product.
at first this cable seems a little cheap but when i got it it is a very nice product the mouse is good for both right and left handed people the laptop has a great curve to it and has the spot below it to put your hands on while you type this may not be soft but still works great it is good for windows 8 too the signal i haven't had a problem it just plugged in worked haven't had a problem at all
Without much changed from the Desktop 3000 - I prefer to order these since they are usually cheaper. I have about 30 sets deployed in an office setting. The only reason I did not give the set a five star salute is that some sets seem to have problems with distances / signal degradation. The custom launcher buttons at the top are life savers and easy to configure with the software that Windows 7/8 installs for you. The mouse is a big big, but tracks well.
Great price, sturdy construction and item(s) perform as required. No problem setting up for Windows 7 Professional, 64-bit operating system.
I bought this for work as and this is the first wireless keyboard/mouse I've ever owned. Advertised 8-12 months battery life with keyboard/mouse so that's cool guess I'll find out in the upcoming months. It's nice a lot of people complain about no LED for caps lock etc but its not that big of a deal. If you do your research up front before you buy you'll already know that. I've used it for about 2 weeks now and I guess the only complaint is the fact that the keys are so close together.
I bought this Microsoft Wireless Desktop set for work after my kids broke the USB receiver for the Logitech MK260 set. I work in the IT industry for the largest IT services provider you can think of, so I use this keyboard/mouse combo about 8-10 hours/day, 5 days/week. I work mostly on the command line level and do some light web browsing, so I can't comment on how well this set would work for gaming or things like that. For what I use it for, it does the job quite well.
The keyboard and mouse both function quite well. Good feel to the keys and all items work as expected. I occasionally have a little bit of lag on the mouse cursor when some other program is running hard in the background on my machine. Not the fault of this product, but not something that you experience with a traditional, wired mouse. My only gripe is the function keys. They are about 1/4 of the standard height and are not clustered in groups of 4 as on a traditional keyboard. It's nearly impossible to operate them by feel.
Answer: According to this link at Microsoft looking at the initial sheet for the downloads it only has  the win 7 that you can select, but if you look at the technical sheet it says Windows 8 and 8.1 are compatible. Based on this i would imagine since it is Plug and play you  might already have the driver on your PC. http://www.microsoft.com/hardware/en-us/d/wireless-keyboard-2000. Hope this helps
