Thank you for posting on the HP Support Community.
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:
- Are you trying to install windows 8.1 updates?
- Are you getting any error message or code?
- Which driver you're looking for?
Keep me posted for further assistance.
