asked on

What use is Windows.old folder after install Win7?

Yes, I know I can delete the large folder: windows.old, which was created by the instal of Win7 64-bit. Clean install upgrade from vista 32-bit.
Can I use some of the program.exe or move the Thunderbird .cvs addressbook files?
and more?
Is the creation of window.old a protection should for re-install of the previous OS?
There was no explanation by Microsoft as to why or what use is the windows.old.
To what use might I put that windows.old, before I delete. When is a "safe" after date of install to delete?
Other thoughts?
thank you,
Jim

windows.old is your previous system - packed up and ready for deletion.
but it's function is to be available if windows 7 initial setup comes in a dead lock
and previous system needs to be restored (before the bootloader gets installed).
this feature you will not see often but very rarely during some failed setup.
you will see (require it) it only when W7 still give you the option in loading the OS.
If you look closely during the installation W7 gives you ,once or twice, the option
to boot your previous system.Once bootloader gets configured,previous system gets 'packed'.
Now,it's there only if you have something to preserve.
programs from the old installation will not work (at least most of them).Those standalone ones will.
You can of course move files from there (like contacts,mail etc...) to new installation folders
(if the programs that made them are the same).
once you take what you need,its perfectly safe to delete....

Once W7 installs you can not restore your previous OS !
No way ...

thank u all; I got it done & with understanding.
Takes awhile to re-establish a well tuned PC with fav. Programs after a clean install.
Win7 seems somewhat faster, nicer, but it should due to the usual 25% increase of positive aspects from a clean install, no matter which OS was cleaned.
