Hi
im trying to downgrade my laptop from windows 10 (originally Windows 8) to Vista ultimate on resetting I've been confronted with the following message:
"Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source."
Is this normal when trying to retrofit Vista? Or something I should be concerned about? I bought the Vista with serial key used but in original packaging from fleabay, it looks legitimate with hologram etc.
What can I do to resolve this? In layman terms please!
Thanks

In reality, Microsoft gains a lot of money from driver publishers in order to allow their products to be installed on Windows OS. Some vendors refuse to pay this impost, and that's why some drivers return "Windows cannot verify the digital signature.." message when being installed. This might happen even with properly signed drivers if Windows driver verification services are corrupted or malfunctioning. Either way, the only reliable and successfully solution is to disable digital signature enforcement for current Windows session. Here's a detail explanation
