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,
