Hi @bojacobsmd, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 

Since your HP 17 Laptop PC 17-cp3000 (799U9AV) is not starting after running a Windows update, try the following troubleshooting steps:

Perform a Power Reset

1. Disconnect all external devices (USB drives, printers, etc.).
2. Unplug the AC adapter and remove the battery (if removable).
3. Press and hold the power button for 30-60 seconds.
4. Reconnect only the AC adapter (without the battery if removable) and try turning it on.

Try Booting into Safe Mode

1. Turn off the laptop completely.
2. Press the power button and immediately start pressing the F11 key repeatedly.
3. If the HP Recovery Manager or Advanced Startup Options appear:
   • Select Troubleshoot > Advanced options > Startup Settings.
   • Click Restart and then choose Enable Safe Mode.
   • If it boots, uninstall the recent update under Settings > Windows Update > Update history.

Boot into Windows Recovery

If Safe Mode doesn’t work, try:

1. Turn off the laptop.
2. Press Win + B, then hold the power button for 2-3 seconds, and release only the power button (keep Win + B pressed).
3. If the BIOS recovery screen appears, follow the on-screen instructions.

Use a Bootable USB (If Nothing Works)

If the above steps don’t work, create a Windows 11 bootable USB using another PC:

1. Download the Windows 11 Media Creation Tool.
2. Create a bootable USB (at least 8GB storage).
3. Insert the USB into your laptop, power it on, and repeatedly press F9 to enter the boot menu.
4. Select the USB and choose Repair your computer instead of installing Windows.

I hope this helps. 

Take care and have a good day.
