In Vista

[squirrel dog]

What are these files on my c drive? From a vista home prem. upgrade

$upgrade.~os
$windows.~bt
91bbacf648b6d80e0c1b
134ffbda2a4ad03e5888...

The reason I'm asking is I don't know,and what do they do?

 

[Dahak]

looks like they where temp files that where not deleted once the upgrade was done

 

[JeffreyLebowski]

I can't say I know for sure, but it sounds like the files needed to restore XP should you not want Vista anymore. Can you even roll back Vista like that?
