I don't have an answer for the Spotify issue that as that is why I'm reading this forum but I do know whats going on with the bad update that screws up USB functionality.
Its a really easy process.
If you computer boots into windows open up a command prompt with administrator permissions. "cmd.exe"
once cmd is up type the following.
Dism /online /get-packages
Find the last rollup update that was installed.
Once you have found the package name you need to remove it.
Type the following:
dism /online /remove-package /packname:[THE PACKAGE NAME HERE]
Replace [THE PACKAGE NAME HERE] with the rollupfix name that you find in your Dism search. - mine is highlighted in red above
so for my issue I typed this: dism /online /remove-package /packagename:Package_for_RollupFix~31bf3856ad364e35~amd64~~16299.248.1.17
after the package uninstalls you will be asked y/n to reboot.
after rebooting your USBs will work again.
** you may have to do this for more than one rollup package.
Good Luck!
