You will be presented with the following screen:
This shows a register change already set for start up, the one for register 52 as you can see.
To set any registers you wish at start up you need to make sure that at the top right it is set to Start..... then simply hit Add to add a new setting to it. You will be greeted with a screen like below:

You simply enter the register number under register and the setting you wish to apply under Data, simple.
Then you'll need to restart once you are done for any changes to take place.
If for some reason windows doesn't like one of your settings and will not load, just hold down the Ctrl key on startup and it will bypass your startup files.
The End
Some of you will have successes with this and many of you will not. You can and very likely will lock up your system while doing this. These changes are by no means permanent. Simply restarting your system will restore anything that has been changed. Always test things with WPCREDIT before setting them in WPCRSET.
Have fun with this guide. Most of the PCR settings are the same as those in Mr Slicks 761 guide. So of course MANY thanks have gotta go out to him since his article is the basis for this one.
