VirtualBox: 64-bit Guest OS

While playing with Vagrant, VirtualBox, and MongoDB on my old ASUS ROG Generation 1 - which has Intel Q720 CPU and runs Windows 10 64-bit - I ran into this error.

VT-x is not available(VERR_VMX_NO_VMX).

VirtualBox error: Intel VT-x is not available

Also, VirtualBox list only 32-bit version for guest OS.

It is so weird because I can installed Ubuntu 64-bit as guest OS in VirtualBox while booting this laptop in Windows 7 64-bit.

I tried removing Hyper-V feature and reboot.

VirtualBox now display 64-bit version of guest OSes.

And Vagrant works too.

[Microsoft Outlook]: Set .pst and .ost files location with ForcePSTPath Registry Key

Set .pst and .ost files location with ForcePSTPath Registry Key The ForcePSTPath registry key is supported by Microsoft Outlook 2003 and later. In Microsoft Outlook 2003 and 2007, it applies to new profiles only. Microsoft Outlook 2013 and Outlook 2016 it applies to new accounts created in a profile. Microsoft Outlook 2013 saves .pst in %userprofile%\Documents\Outlook Files folder by default. We can change that default setting by adding a new string registry key called ForcePSTPath and set the value to the folder that we want to save those files.
