I’m wondering if this will reset the media creation tool on a HP AIO.

 

My simplified method is first to show hidden files and folders, then find the following files:

1. C:\ProgramData\Hewlett-Packard\Recovery\hpdrcu.prc
2. C:\Program Files\Hewlett-Packard\Recovery\hpdrcu.sys
3. D:\hpdrcu.prc

Add .bak to the ends of each of these files eg: hpdrcu.prc.bak
