I want to play Fallout 4 and I found out I need 64bit system in order to play it, but I have 32bit system and I'm capable of upgrading.
Can I reinstall Windows without losing pictures and that stuff if I put them in D:\files or something like that?
I don't want to buy more storage just to save my files.
I also don't want to use Google drive or similar because I have a lot of pictures on my PC.
If you want to move from a 32-bit version of Windows to a 64-bit version of Windows 7 or vice versa, you'll need to back up your files and choose the Custom option during Windows 7 installation. Then, you'll need to restore your files and reinstall your programs. For more information about performing a custom installation, see Installing and reinstalling Windows 7.
Notes
To install a 64-bit version of Windows 7 on a computer running a 32-bit version of Windows, you'll need to start, or boot, your computer using a 64-bit Windows 7 installation disc or files.
If you start your computer using a 64-bit Windows 7 installation disc or files, but your computer isn't capable of running a 64-bit version of Windows, you'll see a Windows Boot Manager error. You'll need to use a 32-bit Windows 7 installation disc or files instead.
