Technical problem with ExpressVPN.
I've been using express VPN for years, well before this latest promotion. It's clearly a solid product I've relied on across all my devices. For users who prioritize security on Windows, there seems to be a problem where after adjusting the CPU clock speed in BIOS, the app needs the activation code again when starting Windows. This service blocks internet access until it establishes its connection through the tunnel. These issues are typically fixed with %appdata wipes, but they can't explain why this is happening now. ExpressVPN is the only one that asks for login after changes. From what I understand, it's not obvious how this works at the moment.
Typically, keys are present in any app to prevent unauthorized sharing of the program. It’s highly probable they’re using one of their countermeasures by checking the hardware and searching for modifications. A developer might have introduced an error where adjusting the boost clock manually is interpreted by the software as a hardware update. This leads users to think the program needs reactivation as if it were on a new machine.
On startup it remains unchanged, yet during OS loading it seems to know the maximum clock speed. If it displays a different value, the program might be using that information. This behavior doesn’t make logical sense—applications shouldn’t turn off when an overclock is adjusted, which is why it’s likely due to a bug. You’ll need to investigate why it acts this way.
