I'm currently running a Windows 10 Ultimate 32-bit and I want to upgrade it. Will I lose my files or will it be there even after the upgrade. I have a lot of important files that I can't really figure it out which one is important until I actually use it, so it'll take me days/months for me to put it in a backup.
There is no Windows 10 Ultimate, do you mean you have Windows 7 Ultimate now ? If you have a 32 bit computer, it must be a few years old that may not be compatible with 10. Before ANY upgrade, I would backup ALL your files and decide later what to delete vs trusting an Upgrade to keep your files, even if you select that option.
Yeah, as in Post #2, there is no such thing as Win 10 Ultimate. The common choices are Home and Professional. If you upgraded Win 7 Ultimate to 10, you'd receive Pro.
It is not permitted to upgrade a 32 bit OS to a 64 bit one. You'd have to do a clean install. With that, you'd wipe everything on the OS partition.
The good news is that your Win 10 license would be equally valid with a 64 bit version.
Why would it take you days or months to backup your data? You should already have a separate backup device. If you use an external HD, you wouldn't choose what files to backup: you copy all files (not the OS or applications). You could also image the existing OS partition, and restore it should something go wrong.
