How can I expand my C drive space on my PC?

First off, do you have any extra NVMe slots available? If you do, that's a great way to add some capacity. If you're okay with using a second drive, consider adding a non-SSD for storing non-essential things like movies and music. SSDs are awesome for performance, but for files that don’t need fast access, a regular HDD can dramatically increase your space at a lower cost. Just make sure your critical system files stay on the SSD. If you’re struggling with performance issues, then cloning your current drive onto a new larger SSD might be the quickest route—especially if everything else is working fine. Starting fresh can clean up the system but isn't necessary unless you're having other issues.

While cloning your drive is a valid option, moving your WSL to a larger drive could really help save space on your C drive. Although WSL shouldn't typically be that large unless you're handling extensive AI/ML datasets, it might be efficient to offload it. Just moving it could free up quite a bit of space. Also, if you do end up going the fresh install route, you’d likely eliminate old drivers and bloated files—which can be a bonus.
