Trying to wrap my head around this one. One of my clients has disabled all usb ports somehow via the Device Manager and I have no inputs on the system.

Newer HP desktop Windows 8.
No PS/2 ports or serial ports on the motherboard.

Have been looking around online and remote registry with no solution so far. Maybe someone has resolved something like this before or maybe I am missing something obvious.

Thanks :)

How do you know they were disabled via DM? Did they give a detailed explanation of how they did this or why? What other troubleshooting steps have you done? You can enable/disable USB, as well as other hardware via regedit, which includes remote regedit. Open the registry for the target machine, HLM>System>CurrentControlSet>Services>usbstor. Value of 4 disables, value of 3 enables.

Client had said they turned them off in the device manager, was trying to disable one. That regedit entry is set at 3.
 
The usbstor keys are normally used to allow or forbid connection of storage devices via USB; from the sound of it your client has turned off the USB ports completely, so that even the keyboard and mouse won't work - otherwise he/she could just of back into Device Manager and turn them back on. Is that right?

Sounds right.
 
Managed to get to system restore. Face palm... HP has a boot menu option to the recovery console I did not see. Thank you everyone.
