Hello there,
I suppose you must update your version of Windows. As a reminder, Windows 8.1 has reached end of support on January 10, 2023. At this point technical assistance and software updates will no longer be provided. If you have devices running Windows 8.1, we recommend upgrading them to a more current, in-service, and supported Windows release. If devices do not meet the technical requirements to run a more current release of Windows, we recommend that you replace the device with one that supports Windows 11.
Windows creates system restore points, which can consume disk space over time. You can adjust the amount of space allocated to restore points:
Go to "Control Panel" > "System" > "System Protection."
Select your C drive and click "Configure."
Adjust the maximum disk space usage.
Hope this resolves your Query !!
