reboot12

For install WinXP from RAM-ISO loaded (nLite integrated WinVBlock driver) need disable CD-ROM drive or/and IDE channel in BIOS to which the optical drive is connected. Please read my thread at reboot.pro :-) Install WinXP from ISO to HDD

Maybe you right but why in cmd working command: vhdmount /u all It does not need to specify the drive letter to umount image VHD. This umount automatic all mounted images.

Mount and Umount from link working good. Now I want only move Umount command to Drive key. Default to umount VHD image need right-click on VHD image. I want right-click to icon drive in My Computer window to umount VHD not for VHD file. I try also option /u all but it did not work :-( from right-click icon drive. Only working in cmd.

Yes, syntax is other but after fix still not working: Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\Drive\shell\Umount VHD\command] @="\"C:\\Program Files\\VHD Mount\\vhdmount.exe\" /u \"%1\""

Default Mount/Umount command context menu is for VHD files. I want change Umount command from file VHD to mounted Drive like this: Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\Drive\shell\Umount VHD] [HKEY_CLASSES_ROOT\Drive\shell\Umount VHD\command] @="C:\\Program Files\\VHD Mount\\vhdmount.exe /u all" but this not working :-( If manually run this command in cmd this working good and umount all mounted images VHD. What's going on? Why this not working from Drive context menu?
