Wireless keyboard suddenly stopped working altogether

Seavixen gave you a few things. Curious, which one worked?

Did you sync the keyboard and the receiver by pushing the appropriate buttons.

Congrats! Glad you got it working!

Sometimes hardware just dies and I would say RIP to your KB.

While that's true, sometimes it pays to read the thread

I have a similar issue after the last batch of Windows 7 "updates". I've done all of the suggestions here, even restoring to a previous state, nothing works.

Here's the scenario. Dell Inspiron 15 laptop. Logitech wireless keyboard and mouse, both using the same wireless "Unifying" receiver. Mouse works, keyboard does not. Uninstalled and reinstalled Logitech Unifying software for the receiver. It recognizes the make and model of my keyboard when I turn the keyboard off and back on again, but it still doesn't work. I also tried plugging in a USB keyboard and rebooting, that doesn't work either. Tried using a restore point prior to the updates, that hasn't helped. Tried a different (Microsoft) wireless keyboard, nothing. The only keyboard I can get to work is the one built into the laptop, which is pointless because I keep it on the keyboard drawer and use an external monitor, keyboard and mouse. I'm thinking it's gotta be a software issue, but I'm running out of ideas. Any help anyone? Thanks!

Further info:

• The keyboard works fine if I boot into safe mode.
  If I boot normally it always tries to installed "USB Receiver" and "USB Composite Device" and then it basically hangs at that point.
  Removing the Unifying receiver and booting normally I can use the laptop keyboard and trackpad just fine, but I get a message to reinstall Setpoint, which I try to do but get a failed message because it is unable to find the resources. Trying to uninstall Setpoint fails also with a dword error.

Other than using a 3rd party utility to uninstall rogue software (setpoint)and uninstalling the Unifying software and rebooting I'm not sure what else to do. Obviously Setpoint and my USB receiver drivers are corrupted, and the fact that both work fine if I boot into safe mode is odd. And even though I boot into "safe mode with networking" I still cannot get onto the internet in that mode so the Setpoint software fails to uninstall or reinstall since both access the internet. This is extremely frustrating. Does anyone have any other ideas of what I can try?
Thanks!
