@SimSen69, Welcome to the HP Support Community!
Thanks for reaching out about your query regarding your HP Pavillion 15 windows update!
We're thrilled to have the opportunity to assist you and provide a solution.
I see you're having trouble updating your HP Pavilion 15 from Windows 8 to Windows 10. No worries—let’s get this sorted out!
A few quick things to check first:
System Requirements: Make sure your laptop meets the minimum requirements for Windows 10. Most Pavilion 15 models should be fine, but it's always good to double-check.
Storage Space: Windows 10 needs at least 16GB (for 32-bit) or 20GB (for 64-bit) of free space. If you're low on space, try deleting unnecessary files or moving some data to an external drive.
Windows Update Readiness:
Install all available updates for Windows 8 first.
If you haven’t already, download the Windows 10 Update Assistant from Microsoft’s official website and try running it from there.
BIOS Update: Sometimes, an outdated BIOS can cause issues. You can check for updates on HP’s support site by entering your laptop’s model number.
Installation Hiccups: If the update is failing at a certain percentage (like stuck at 99% or throwing an error code), let me know what error message you're seeing—I can help troubleshoot further!
If the update still won’t go through, you might need to create a bootable USB drive using Microsoft’s Media Creation Tool. Let me know how it goes or if you need a step-by-step guide—I’m happy to help! 😊
Looking forward to your update!
Take care, and have an amazing day!
