i using win 7 pro..but i cannot start defragment..so i cant shrink volume hd because this 2 thing are related...so what must do??? my restore point not work
Virtual disc programs like magicdisc can cause this behavior with win 7. If you have one of those installed try and disable the virtual drive(s) created by it or maybe uninstall it - let me defrag after that...
If you can give a bit more detail, it might be a bit easier to help out. Is there some sort of error that appears when trying to start defragmenting? Do you have a SSD drive? (Defragment is turned off in Windows 7 automatically when an SSD is detected to better protect the drive.) Little bits and pieces.
