Steven15 Sorry to hear you are having trouble with Windows updates and slow system boot after updates.
Could you tell us more details:
- Does it get stuck during Windows update installation?
- How long does it take to boot up after the update?
You may try these steps first:
- Run Windows Update Troubleshooter to fix update errors.
- After updating, try disabling fast startup in Windows power options, it often causes long boot time.
- If the update fails repeatedly, reset Windows update components.
Looking forward to your reply.
