Method 2 of 6: Check hard drive space on Windows

You may notice a difference between the total number of gigabytes on the hard drive and the number advertised when you bought the computer. This is the case because part of it is used to store the operating system, which is why this space is irreversibly occupied and it does not appear on the list

Advice
RAM is memory that is allocated to different programs (such as software and applications). The hard drive, on the other hand, is the memory in which files, folders or programs that you keep on your computer are stored, whether it is running or not
Warnings
- If a questionable process is using a lot of RAM, try running a scan with your antivirus.
- Only kill processes that are not essential to the operation of the system. You could easily irreparably damage files and data that powers your device.
