Use Disk Cleanup to delete all but the latest System Restore Points.
Press WINKEY+R and type cleanmgr.exe and press OK.
Select Files from all users on this computer.
Leave all of the default check boxes selected.
Click the More Options Tab.
In the System Restore and Shadow Copy section, select the Clean Up button.
In the confirmation box, select the Delete button.
I don't recommend turning System Restore off because this can help to
recover recent files created between the times when you run Acronis.
