In the case that Windows 10 cannot enter the desktop after booting, we can use the elimination method to solve the problem step by step.

Restart your computer: Sometimes, a simple reboot can fix a lot of problems. After Windows 10 boots on, you can try to press Ctrl+Alt+Delete and then select "Shut Down" - "Restart" to try to solve the problem.
Check your startup items: Sometimes, some unnecessary startup items can cause slow boot or problems. You can press the win+r key combination to open the "Run" dialog box, enter msconfig, and then select the "Startup" tab, disable all unnecessary startup items, and then restart the computer, and then slowly eliminate it after normal.
Check your keyboard and mouse connection: Sometimes, there may be a problem with your keyboard or mouse connection. You can try connecting your keyboard and mouse to a different USB port or use a different keyboard and mouse to try to fix the problem. Check your network connection: If your computer is connected to a network, you can try checking if your network connection is working. You can try disconnecting from the network and then reconnecting to the network to try to resolve the issue.
Check the hard drive: If there is a problem with the hard drive where the Windows 10 system is located, such as file corruption or disk error, it can also lead to the issue of not being able to get into the desktop. You can try to use the disk utility that comes with your Windows system to check and fix the problem.
Restore the system: If none of the above methods can solve the problem, you can consider using the recovery function of the Windows system to restore the system. You can press the F8 key to enter "Advanced Boot Options" while booting up, and then select the "Repair Computer" option to try to fix the problem. 
Hope the above methods can help you solve the problem. If the problem persists, it is recommended to consult a professional technical support staff or leave a message or private message in the comment area. ’
