Uvolnění místa na disku instalace Windows (WinSxS)

The component store cannot reside on another volume other than the system volume due to the use of NTFS hard links. Attempting to move the component store will result in the inability to properly install Windows updates, Service Packs, roles or features. Additionally, it is not recommended that files be manually removed or deleted from the component store.

To reduce the size of the component store directory on a Windows installation you can choose to make the service pack installation permanent and reclaim used space from the Service Pack files. Doing this will make the Service Pack permanent and it will not be removable.

To remove the Service Pack files from a Windows installation use the following in-box utilities:

  • Windows Vista or Windows Server 2008 Service Pack 1: VSP1CLN.EXE
  • Windows Vista or Windows Server 2008 Service Pack 2: Compcln.exe
  • Windows 7 or Windows Server 2008 R2 Service Pack 1: DISM /online /Cleanup-Image /SpSuperseded or Disk Cleanup Wizard (cleanmgr.exe)

Scavenging may also be proactively performed on Windows Vista and Windows 2008 installations by forcing a removal event on the system. Scavenging will attempt to remove any unneeded system binaries from the installation and allow Windows to reclaim the disk space. To issue an uninstall event on a Windows installation, simply add and remove any unneeded system component that is not already installed and reboot the Windows installation. Scavenging will be performed during the subsequent reboot of the operating system.

NOTE: Scavenging is performed automatically on Windows 7 and Windows 2008 R2 installations
