    Running your Browser in a VM?

    • Install VMware Player or Virtualbox, VMware being faster in my experience
    • Create a VM with sufficent RAM HD and all CPU cores
    • Install Ubuntu/Linux Mint/Debian or some lightweight distro with Xcfe or LXDE
    • Install VMware/Virtualbox tools
    • Almost any distro comes with Firefox
    • Install Ublock Origin/Noscript/Ghostery
    • Disable cookies with a whitelist/use private browsing.
    In my experience, running a browser through a VM can slow down scrolling smoothness, video playback and increase ping delay

    Fix Slow Internet in VirtualBox VM

    VirtualBox VM activation of Preview build 17763.104

    I had issues with my Linux Mint 18.3 host using a VirtualBox VM of Windows 10 pro preview build, so I followed the procedure to "export" The Windows 10 VM and also saved the original VM intact in a separate folder on my data drive. After a clean install
    of Linux Mint 19 and installing the latest version of VirtualBox available in the repos I then imported the VM of Windows 10 that I had previously exported. This went smoothly enough, but the Windows 10 (Build 17763.104) now says it is not activated - whereas
    it has previously been activated for years through successive preview builds and even different versions of Linux Mint and VirtualBox versions (I don't recall ever having to activate it). I thought maybe the "export" of the VM was the issue, so copied back
    the ORIGINAL and UNCHANGED Windows 10 VM folder and opened that in VirtualBox. Now even that original Windows 10 Pro Preview build is no longer activated despite NO CHANGES to the VM itself from the previous hour before I reinstalled Linux Mint and VirtualBox.

    How do I activate this? I have never had to before and have used this VM for years with every Insider preview update sent out.
