Windows 8.1 freeze on any hardware scan or changes. USB wireless keyboard mouse not working

Problem : System Freezes frequently on any hardware scan or changes.
Symptom : Wireless Keyboard Mouse not working.
Caused by : VMkbd.sys located in C:\Windows\System32\drivers.
Issue : VMware player or VMware Workstation installed on Windows 8.1 causes compatibility issue leading to system freeze
Soultion : Please follow steps below
Step 1: Start > run > regedit
Step 2: Locate to this registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e96b-e325-11ce-BFC1-08002BE10318}
Step 3: On the left side plane, Right click on the registry {4d36e96b-e325-11ce-BFC1-08002BE10318} and then export it as backup. Just to be safe.
Step 4: Edit the UpperFilters, The value current would be kdbclass vmkbd. Remove the vmkbd. So only value left would be kbdclass.
Step 5: Restart your system and connect your USB wireless reciever. If all is well it will not freeze your windows now.
This worked for me. Hope this works for you. Enjoy..!!

Keyboard mouse not working after Windows update

Question was asked and supposedly answered b4, but didn't tell how to work around no keyboard or mouse. Ie: how do u get to device manager without keyboard/manager? I unplug to reboot and up down keys work in startup. However, when I open in safe mode, keyboard and mouse still don't work.
Windows 7- 64 bit

USB Ultranav keyboard does not work with Windows 7

Hi, I recently installed Windows 7 to my Dell Latitude XT tablet and was disappointed to learn that my USB Ultranav Keyboard only works as a keyboard and not a 'mouse'; that is, the ultranav devices (touchpad, buttons, and trackpoint) do not work. I have not had problems with the keyboard functioning in XP or Vista, so it was surprising to find that it will not work with W7.
I thought all was going well when W7 recognized the Ultranav keyboard when I plugged-in the device, but all did not go as planned. I let W7 find the drivers through Windows update, but then once they didn't prove to work, I followed W7's directions of reinstalling the drivers in its version of 'Compatability Mode', but that still didn't prove to work. I would really appreciate any insights into this problem as it is one of my only (current) hesitancies about using W7.
Thank you for your time and attention to my inquiry.
Cheers,
Tsugazi

Hi, strangely enough, I got it to work. Here's the what I did differently (for those with a similar problem):
After installing W7, I plugged in my keyboard and let Windows find the drivers. When this didn't provide functionality of the ultranav devices, I tried installing the Ultranav drivers, and when Windows said there was a compatability problem, I then opted to let Windows re-install the Ultranav driver. Unfortunately, this didn't provide functionality either.
Jump ahead 12 hrs and re-install of W7 (for other reasons). This time out, I installed the Ultranav driver, THEN plugged in my keyboard. Everything works now! I don't know that this sequence will work for everyone, but it did for me.
Thanks for your comments.
Cheers,

Windows via Bootcamp keyboard/mouse not working???

I have a 15" Macbook Pro and have installed Windows 7 Ultimate via bootcamp with all the correct apple support drivers but suddenly my keyboard/mouse will not work at the sign in screen for Windows at all. Up untill this point I could restart my mac and resign in through the windows partition and easily play my favorite games. Recently I tried signing into windows but at the sign in screen I cannot use my mouse nor my keyboard. Please do not tell me to reinstall windows unless that is the only solution because of data not backed up. Is it a driver issue, how can that be because it worked fine for weeks? Please get back to me as soon as possible!!
Specs:
Processor 2.6 GHz Intel Core i7
Memory 8 GB (Raam) 1600MHz DDR3
Graphics NVIDIA GeGorce GT 650M 1024MB
Software OS X 10.8.2 (Mountain Lion)

If the mouse and keyboard are working under OSX then it can't be a hardware issue.
You could try:
starting Windows in safe mode to see if the mouse and keyboard work. (Press F8 repeatedly just before Windows starts to boot to bring up the Windows boot menu.) Safe mode loads a set of basic drivers to just get Windows running and no more.
Another thing you can try is unplug the mouse and re-plug it in after a few seconds while at the login window. The USB ports may re-detect the mouse.
Try booting from a Windows PE CD or USB stick if you have one. If the keyboard and mouse work under Windows PE then it's probably a driver issue under your Windows install.
Did you install anything under Windows before this happened?

Apple wireless Mighty Mouse not working in Windows XP Pro/Boot Camp

I was able to get Windows XP Pro to install successfully on my new iMac, but I can only get a wired Microsoft USB mouse to work with it. When I boot to WinXP with just my wireless Mighty Mouse, the wireless mouse is completely unresponsive. Has anyone else experienced this, and is there a solution? Thanks!

Wireless keyboard doesn't work in Windows!!

Wireless keyboard works fine in Lion system, but I cant unpair it in Lion system since it is undetectable. After installing Windows 7 through boot camp, the wireless keyboard is not working. I think it is some kind of driver problem. Can someone help me solve this problem? Thanks a lot!!!

Hi JPasHPCust,
Welcome to the HP Forums!
I have read your post on having trouble utilizing your wireless keyboard to the desktop, and I would be happy to be of assistance!
To start off, I will need to know what the Product and Model Number is for your desktop. I will also need to know if your wired keyboard is capable of functioing in a different USB port or not.
Please follow this document on Wireless Keyboard and Mouse Troubleshooting. If you still cannot use the wireless keyboard, try booting your computer in safe mode. To do this, follow these steps to boot in Windows 8 Safe Mode.
Please re-post with the results of your troubleshooting, and I look forward to your reply!

I just replaced the batteries in my wirless keyboard. I am running Windows 7 through Bootcamp. Since changing the batteries, the keyboard will not work in the Windows partition; however, it is working fine in the OSX partition. I would appreciate any suggestions as to how to correct this. I am of an advanced age and am technologically challenged. Thanks so much!

This may be just a Boot Camp issue, if no one here can help you may also want to post in the Boot Camp forum.

My USB ports will not recognize any devices, iPhone or external drives. Keyboard and printer work, any suggestions?

My USB ports will not recognize any devices, iPhone or external drives. Keyboard and printer work, any suggestions?

I'd start by looking in system profiler.
the blue Apple icon > About this Mac > More info...
goto the hardware section. Scroll down and click on USB
See what happens when you have the device plugged in & not plugged in.
Move keyboard & mouse around to verify that ports work. Plug device in a port that worked with keyboar or mouse. Keyboard usb ports are rather low power.
Perhaps device is taking too much power. Are devices power or unpowered? Try connecting devices to a usb hub.
Which mac do you have?

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem. Likey a bad digitizer

Are you connecting your iPhone directly to your PC or to a USB hub?

Any ideas why my ipod nano 6th gen is not working with Sony SRSGU10IP docking station pls

any ideas why my ipod nano 6th gen is not working with Sony SRSGU10IP docking station please ? classic working fine, so not the fault of the station itself ? it's been bought as a present for my father & he's confused !

Check the headphone jack with a flashlight and clean it if necessary. The jack on a new Nano is very tight, be sure you push the headset jack all the way in, the plastic on the headset jack should be flush with the body of the Nano.

My Macbook Pro keyboard AND USB keyboard will not work. However, the trackpad and USB mouse will work. Any help?

This is quite frustrating, since it randomly occured as I was browsing the web. It seemed to happen out of nowhere. I cannot login to my user account because I cannot type my password.
Any help will be appreciated.

If you have another Mac, boot the non-working one into Target Disk Mode (holding down "T" at startup). Hook up the two Macs via a Firewire cable. The non-working one will mount on the other Mac as an external Firewire HD.
Next, download the 10.5.6 Combo update from here:
http://www.apple.com/downloads/macosx/apple/macosx_updates/macosx1056comboupdate .html
Run it. When it asks you for a destination, choose the other Mac that was mounted via Firewire. When it's done, unmount the computer and restart it. The keyboard and mouse should work now.
