Windows 10 kbdclass.sys errors are caused by a keyboard or keyboard driver that Windows doesn’t like. It is usually a driver file or compatibility issue but can also be caused by a driver overwriting a Windows core file. Fortunately, it is relatively straightforward to fix Windows 10 kbdclass.sys errors. Here’s how.
Windows 10 kbdclass.sys errors tend to appear in three guises:
• STOP 0x0000000A: IRQL_NOT_LESS_EQUAL – kbdclass.sys
• STOP 0x0000001E: KMODE_EXCEPTION_NOT_HANDLED – kbdclass.sys
• STOP 0×00000050: PAGE_FAULT_IN_NONPAGED_AREA – kbdclass.sys
All three generally result in a BSOD. They will most likely occur just after adding new hardware to your system or just after upgrading or installing Windows Small Business Server.
Fix Windows 10 kbdclass.sys errors
There are a couple of ways to address these errors.
1. Remove all external hardware from your computer except keyboard and mouse.
2. Reboot and retry.
3. Gradually add hardware until error reappears then change the port that hardware plugs into.
Or:
1. Navigate to Control Panel, Hardware and Sound and Device Manager.
2. Find Keyboards and right click.
3. Select Update Driver Software and use the automatic option.
4. If automatic driver update doesn’t work, download the latest driver manually and force an update.
Or:
Uninstall or undo any changes you performed before the error began occurring, especially anything to do with Windows Small Business Server.
Or:
1. Open a CMD window as an administrator.
2. Type or paste ‘sfc /scannow’ and hit Enter.
3. Allow the process to complete and make any repairs.
Windows 10 kbdclass.sys errors are quite rare, as most reports of the error revolve around Windows Small Business Server 2011. Usually, just removing the keyboard, updating drivers or even moving the USB slot it uses is enough. Otherwise, one of these steps should help.

This is NOT a list of tasks/processes taken from Task Manager orthe Close Program window (CTRL+ALT+DEL) but a list of startup applications,although you will find some of them listed via this method. Pressing CTRL+ALT+DEL identifies programsthat are currently running - not necessarily at startup.Therefore, before ending a task/process via CTRL+ALT+DEL just because it has an 'X' recommendation,please check whether it's in MSCONFIG or the registry first.An example would be 'svchost.exe' - which doesn't appear in either under normal conditions but does via CTRL+ALT+DEL.If in doubt, don't do anything.
