Hi dolphin99, welcome to 7F!
You have bigger problems than wanting a keystroke workaround.
In your first post you mention "frozen programs
", and in your next "Programs freeze because my Windows 7 Ultimate x64 can't update no matter what I do
Here's what you should do, go to: Windows Updates & Activation - Windows 7 Help Forums
and start a thread there taking notice of the posting instructions at the very top of the page.
Give a short synopsis of your updating problems, you could even insert a link back to this thread for reference only
Once you get your updating problems squared away, and you're still having problems with programs freezing, you may be asked to start a new thread here: BSOD Help and Support - Windows 7 Help Forums
Then we can see if you need more help finding that elusive keystroke.
