IMO this would only be an issue if they advertised that it was overclockable.
If it was advertised with no ability to overclock, you should assume it can't overclock and if you are able, don't assume it will work or will stick around forever.
I have been 'required' to install BIOS updates before. PS3 lost capability's at one point in an update and new games forced that update without mentioning it on the packaging.
"Note that Intel paired this with a bug fix for the freezing during Prime95 - if you want the bug fix, you have to let them lock down your clock. "
They could theoretically push the microcode out via Windows Update as well, which combined with Win10s enforced updates would make it difficult to avoid.
upgrading the OS, which you are required for security reasons, will also upgrade the micro code. in fact, i don't remember the bios ever being relevant for that
> don't assume it will work or will stick around forever.
I agree with the first part, but no with the second. I don't like manufacturers deliberately breaking products which have already been sold, especially in cases when the sale wouldn't have happened if the product weren't better than specified.
Today it's Intel removing not advertised features, tomorrow it'll be Sony removing advertised ones (or had they already done that?)
