Notes about the WPH file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The WPH file type is primarily associated with 'Acer' by Acer, Inc.. The file should come with a README file that tells you exactly how to update the BIOS (e.g., which utility program you'll need to run to flash the BIOS).
