Hello,
Thank you for keeping us updated on the issue and apologies for late response.
You may try Windows Compatibility Mode to use an old program with new Windows.
Kindly refer to: **Make older programs compatible with this version of Windows**
In order to uninstall the BIOS update and bring it factory settings, I would recommend contacting the computer manufacturer for the best support.
IMPORTANT: Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.
Hope this information is helpful. Do feel free to write to us in case if you have further questions related to Windows. We'll be happy to answer.
