Thanks for your tips. I have a few questions.
First of all, the Hiberfile unfortunately only freed exactly 3 GB. It is still useful, of course, but damn it would be hell of a miracle if it really freed 8GB of space.
Pagefile: Question - why do I need it? Can I turn it off entirely, to free the 4 GB that it uses, just until I finish the upgrade? And then turn it back on when I'm done upgrading? Would that be ok?
System restore: Same question, can I turn it off completely until I finish the upgrade so that I free up space? I currently have 9 GB free, but the upgrade set up still needs the 16 GB, so if I free 4 GB by disabling the page file I should have 13 GB, and maybe I could get several more GB from disabling system restore? If there's anything else left over I could probably squeeze another GB or so out, I guess...
Windows.old: are you saying that the upgrade actually does create a new windows folder, and does NOT overwrite the old one, but actually leaves it? Well, I guess that explains a lot. However, just to make sure, after I delete the windows.old folder if I successfully upgraded, (and currently my OS weighs around 15 GB), then I will have around 15 GB free, right?
If so, then I can obviously enable pagefile and system restore back and should be ok. Please respond, thank you.
PS: Speaking of using system restore, I never use it. My windows always runs fine. I think turning it off (and the pagefile too) temporarily just for the duration of the upgrade is ok, but I need you to confirm all of this please. Cyberized:
Can you please make your own thread and not try to hi-jack mine? You have more chances for response if you make your own thread. Thanks.
