What is System Reserved Storage?

System Reserved Storage is a Windows feature that reserves a partition of your hard drive or SSD for critical system functions. Instead of allowing all available disk space to be used by apps and personal files Windows keeps a certain amount of dedicated storage space ready for system use.

  • Windows Update files
  • System caches
  • Language packs
