I'm having a frustrating issue with my Windows 10 laptop. Despite having no software installed, I keep receiving notifications that my disk space is full. I even checked all my folders but didn't find anything unusual. I have Windows Defender up to date, so I'm wondering if this could be caused by malware. To make matters worse, my laptop has shut down unexpectedly three times while it was plugged in today. Any suggestions on how to fix this?

Gotcha! Once you've pulled up Disk Management, take a screenshot of the visible partitions on your disk and share it here. That can give us some clues on what’s going on.
First, try this: on your keyboard, press the Windows key and E at the same time to open File Explorer. Then navigate to "This PC" and find your "C:" drive. Check the bar under "C:"—if it's fully red, you're out of space. If it's partially blue, you've still got some room. Let me know what you see, and I can guide you on the next steps!
You might want to download a program like WizTree or WinDirStat. These tools can help you identify what's actually taking up space on your hard drive. They provide a visual breakdown, which makes it easier to spot any huge files or folders you might have missed.
You should also check your Disk Management settings. Go to Computer, then Manage, and select Disk Management. Posting a screenshot of that can help us see if there are any hidden partitions consuming space.

It's showing red but I haven’t downloaded anything! I'm confused about what's taking up all that space.
