Also, you can use this little program by me to disable sync and set the date for MSVPC. Be aware that it requires .NET Framework 4 Client Profile, if you don't have it yet.

I couldn't get this method to work and the only thing that worked was setting the time on my host PC.

A) This tutorial was written in 2007. I think the VMWare snippet has a few extra lines required these days.
B) Changing your time on the PC? Pffft. Bit drastic. I almost never set the date back when installing betas these days anyway, because laziness/I forget. Can generally work around it regardless.

Except for builds which refuse to install without a proper date (Whistlers, Neptune, possibly Millennium). Or is there a way to bypass that?

With Whistlers and Neptune, I engage my l33t hax0r mode and Shift+F10 and set the date back using the command line in the ~20secs you have before it does the date/time check on the first boot. It'll reset to the correct time at next boot, but it's never been an issue for me.

Not sure about Millennium.

Didn't know that trick, thanks for telling.

Regarding hounsell’s trick, it doesn’t change back in vbox

Good to know I wasn't the only one who did that

The link seems to be broken. Can anybody provide me the application? Thanks.

It's listed on TCB downloads.

If you're talking about my Virtual PC Toolkit program, it's available on TCB or here.

Oh really? Its not on https://thecollectionbook.info/information/downloads/

Also the other website is down

"here" is a clickable link. Anyway... : https://www.krnl386.com/vpctoolkit/vpctoolkit.zip

It's under Information > Changing BIOS dates, where it's always been. Though perhaps Downloads would make more sense.

And the website I originally linked to is long gone, hence why I provided a new link.
