Windows 10, Synaptics touchpad settings lost on logout/reboot

Open up regedit.exe
Navigate to:

HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTP\Install

Note this is LOCAL MACHINE, not CURRENT USER.

Look for a key in that Install folder called DeleteUserSettingsOnUpgrade

Double click and change the value to 0.

Now go back to the Synaptics control panel, set everything how you like, and reboot.

VirtualBox – Cannot Register the Hard Drive Because a Hard Drive with UUID Already Exists

I was trying to attach an existing .vdi hard disk and I got this error:

Failed to open the disk image file C:\Users\Boso\.VirtualBox\HardDisks\WinXP EEE Light.vdi.

Cannot register the hard disk 'C:\Users\Boso\.VirtualBox\HardDisks\WinXP EEE Light.vdi' {9ef5aad7-a03c-479c-a583-8c017acc144c} because a hard disk 'C:\Users\francesco.bosetti\.VirtualBox\HardDisks\WinXP EEE Light.vdi' with UUID {9ef5aad7-a03c-479c-a583-8c017acc144c} already exists.

Result Code: E_INVALIDARG (0x80070057)
Component: VirtualBoxWrap
Interface: IVirtualBox {0169423f-46b4-cde9-91af-1e9d5b6cd945}
Callee RC: VBOX_E_OBJECT_NOT_FOUND (0x80BB0001)

The solution is to run this command:

C:\Program Files\Oracle\VirtualBox>VBoxManage.exe internalcommands sethduuid "C:\Users\Boso\.VirtualBox\HardDisks\WinXP EEE Light.vdi"
UUID changed to: 3b27ce3e-6f95-4873-9561-5d4e28ea8f50

Note that internalcommands and sethduuid need to be lowercase!


Works on VirtualBox v5.0.14
