Making Shrink Volume Work
To absolutely ensure that you can shrink the volume, you should disable as many of the system files as you can, at least temporarily. Here’s the list of steps:
- Run the Disk Cleanup Wizard, making sure to remove the hibernation file and all restore points.
- Disable System Restore
- Disable the pagefile ( Open up System in Control Panel, then Advanced System Settings \ Advanced \ Performance \ Advanced \ Change \ No Paging File.
- In the same Advanced Settings, go to Startup and Recovery \ Settings and then change the Write debugging information drop-down to “None” to disable the kernel memory dump.
- Disable Hibernation mode in your power options \ advanced power options screen.
- Reboot the machine, and then delete your c:\pagefile.sys file, following these instructions if you are having issues.
