Very often you will find that despite it being enabled in the BIOS, the NUMLOCK does not stay on after rebooting. There are various ways that you can try and get it to stay on (log out from the CTRL-ALT-DEL screen with it enabled).
However the option is actually controlled by a registry setting, which you can make yourself.

- Click the Start button, click Run, and then type Regedit in the Open box. Click OK. The Registry Editor window appears.
- Click the plus (+) sign next to the following Registry keys: HKEY_USERS DEFAULT Control Panel
- Click on the Keyboard registry key to highlight it.
- On the right pane, right-click the InitialKeyboardIndicators and click Modify.
- In the window that appears change the value to 2.
- After changing the registry key, click the X in the upper right corner of the Registry Editor window to close it.
- Click Start, then click Shut Down, click Restart, and then click OK. This will reboot the machine, making any registry changes final. Upon reboot, the Numlock light should stay illuminated.
If you are not comfortable with making registry changes, then copy and paste the following text in to notepad and save it as numlock.reg, changing the file type to All Types so that it is saved as a registry file. Then double click on it to install.
