It varies. If you follow my approach—placing OS partitions like C:\ OS (SSD) and D:\ Programs/Games (SSD)—then a 100GB partition is safe. On my system with a 256GB SSD, I have 74GB running Windows 8.1 after an OS upgrade and several updates. Even with the changes, I’m still functioning well. Remember, I moved important files to D:\, which is straightforward: right-click each folder, go to properties, check the "Location" tab, and adjust if needed. The benefit of this setup is that when formatting or reinstalling, I only affect C:\ (Windows and Windows-only files), so my data stays secure. If I’m using dual boot with Windows 10, my files are reachable from both systems, eliminating concerns about where to store work. This method also lets me reinstall apps and games without taking up extra space, as the registry and DLLs are handled efficiently.
