    Hi,



    Windows Restore Points does eat up tremendous amount of your disk space and clearing it would indeed help free up some space. Aside from restore points, there are other invisible factors that can eat away your hard drive space like temporary and cached files.
    For us to better understand why you keep on getting error messages about your storage space being full, we would like to ask the following questions:

    • When did you first encounter the issue?
    • Which Windows version and build is you device running? Type winver on the search bar, and then press
      Enter to find out.
    • What specific error message or error code did you get?
    • Could you repost the screenshots again?


    In the meantime, we suggest you check the steps provided by Greg Carmack on this

    thread
    about clearing system and reserve after an upgrade and see if it helps.



    We look forward to your response.

    Hello,

    The system and reserved files may continue to consume space due to a certain service log that could add to your system as a result of multiple operations. At this moment, we suggest that you run
    CHKDSK command prompt by following the steps below:

    • Plug in your external hard drive, USB drive or memory card to PC.
    • Open Command Prompt; then, press Windows key + X button and select the
      Command Prompt (Admin) option.
    • In the new Command Prompt window, type chkdskE: /f /r. Here, you should replace E with the drive letter of your external hard drive or USB device.

    Note: This operation will run CHKDSK to check and repair file system corruption, errors, corruptions or bad sectors on the external hard drive or USB disk.

    It is also advisable to manually delete files in C:\Windows\Logs\CBS. To do so, follow the steps on this article:

    Clean Up Component-Based Servicing logs
    .

    Let us know the result and progress of your troubleshooting.
