Luciana, Welcome to the Sevenforums!
I am afraid I am having a hard time understanding all of what you meant to say. I have taken the liberty of writing it out as I read it, based off of what I could understand, but please correct me if I got any of it wrong.
A week ago I tried Windows 7 Enterprise x86 (32bit) on my old XP Professional (with SP3) computer.
After the windows updates, I deleted (at my own risk) these folders:
\ - C:\WINDOWS\$hf_mig$\ - C:\WINDOWS\$NtUninstallKB********$ (All of this folder)
This way I am able to save more space
Does anyone know if Windows 7 uses these folders?
Thank you in advance!
Luciana, I have the download folder in windows 7:
But I could not find the other folders, So I am not sure about them
