Windows Install Date Thingie: I made it!

<< < (11/16) > >>

My xp machine:

My 9x machine:

I guess it isn't 9x compatable.  :(

The real original install date is some time back in September 2002 with a repair install done over original on 10/1/2004 which changed the date. (a botched IE 6 update I couldn't roll back screwed up Explorer, needed to revert to original IE 5.5 to repair)

No drive images involved in obtaining those dates on either machine...all natural.


If you would like to make your little app 9x compatable, on a 9x system I believe the reg key would be:

Do I get the award for newest install?
Also, this is an image - the actual "install" was only like a week ago...

OOooh, I forgot about this wee beastie.  It's been, after all, more than 24 hours. :-)

I need to break it open again and see where I went wrong with the date conversion.

Just ran across this and thought I'd give it a try.  The horror!  It's been running the same installation ever since it was purchased.  I don't have any disk imaging strategies or of the many projects that have been put aside while I try to finish my PhD.

Incidentally, all you multiple-install folks, do any of you have any experience with re-activating MS Office?  I am using a technically borrowed computer (belongs to my Dad) which has Office 2003 Pro, acquired through his company for a discount.  I'm not certain if the license is part of their group license, or if it is Dad's own personal one.  Dad doesn't know, either.  Is there any way to find out from the computer itself?  And if I try to reformat and reinstall, can I re-activate Office using a burned copy of the Office CD (Dad has the original on the other side of the Atlantic) and the key information as reported by Belarc advisor, or is there another piece of info that I need?

That's the one thing that has been stopping me from trying any reformat or repair operations.  It's running fine, albeit slowly, and I am afraid to try anything lest I screw up Office.  I'm also familiar with the alternatives (OOo, etc.) and I'm actually using LaTeX to produce the final output, but I have yet to find anything that rivals Word's outline view. 

Unless anyone has a suggestion for the latter....?   ;)

Apologies if this is in the wrong place!

Stoic Joker:
Not sure if this is OK, but here is the code for a commandline uptime utility I was playing with awhile back.

Crap... I can't find the code tags so this will look terrible...Sorry!
