Windows 10: Slow Scanner after clean install win 10 FU

I have a HP 6500A AIO printer-scanner. After a clean install Win 10 FU, it's extremely slow to load the scanner. It is on a network. It has latest HP drivers.

error 45 with sd drive kingston

win 10, clean install.....

thought it was in once after the clean win install

but system seems slow and the Kingston drive was used for cache to increase processing

now I get this error 45.... (device not installed)

went to manager and it is NOT there even after multiple refreshes

 

Upgrading from Windows 8.1. Professional retail product key to Windows 10 -- what happens to your product key and right to reinstall?

My win 7 ultimate is acting "funny" especially in email; computer seems slow; will win 10 fix these things?

Can I reinstall win 10 after the upgrade (clean install?)

Should I reinstall win 7 before the upgrade or does it matter; can I do a clean install after the upgrade?

If I clean install win 7 do I have to restart the reservation?

Can I clean install win 7 after the upgrade and still have win 10?

How can I tell if my win 7 ultimate, 64 bit is considered a retail version or an oem?

I have too much data in my recovery disk partition (2 backups, I think); will win 10 fix this or what's my best approach to rectify?

I suspect a clean install is likely the best remedy to get to pristine?

 

I found that with both the CU and FCU I had issues with my HP printer (5610v). Instead of spending countless hours on searches for a fix.....I just simply uninstalled my driver/software and downloaded a new copy and installed it. With each update and each uninstall and reinstall of printer.....my printer works perfectly.
