stop save to onedrive

http://www.pcworld.com/article/2993360/windows/how-to-stop-windows-10-from-saving-files-to-onedrive.html

Right-click Documents in the Navigation pane (I’m referring to the Documents library, not any of the folders listed below it) and select Properties. In the resulting dialog box, select the local location (probably C:\Users\yourname, where yourname is your login name) and click Set save location button.

System requirements for Hyper-V on Windows Server 2016

https://technet.microsoft.com/windows-server-docs/compute/hyper-v/system-requirements-for-hyper-v-on-windows

General requirements

Regardless of the Hyper-V features you want to use, you'll need:
  • A 64-bit processor with second-level address translation (SLAT). To install the Hyper-V virtualization components such as Windows hypervisor, the processor must have SLAT. However, it's not required to install Hyper-V management tools like Virtual Machine Connection (VMConnect), Hyper-V Manager, and the Hyper-V cmdlets for Windows PowerShell. See "How to check for Hyper-V requirements," below, to find out if your processor has SLAT.
  • VM Monitor Mode extensions
  • Enough memory - plan for at least 4 GB of RAM. More memory is better. You'll need enough memory for the host and all virtual machines that you want to run at the same time.
  • Virtualization support turned on in the BIOS or UEFI:
    • Hardware-assisted virtualization. This is available in processors that include a virtualization option - specifically processors with Intel Virtualization Technology (Intel VT) or AMD Virtualization (AMD-V) technology.
    • Hardware-enforced Data Execution Prevention (DEP) must be available and enabled. For Intel systems, this is the XD bit (execute disable bit). For AMD systems, this is the NX bit (no execute bit).

Shielded virtual machines

These virtual machines rely on virtualization-based security, which supports several new features in Windows Server 2016w.

Host requirements are:

UEFI 2.3.1c - supports secure, measured boot

The following two are optional for virtualization-based security in general, but required for the host if you want the protection these features provide:

TPM v2.0 - protects platform security assets

IOMMU (Intel VT-D) - so the hypervisor can provide direct memory access (DMA) protection

Virtual machine requirements are:

Generation 2

Windows Server 2016, Windows Server 2012 R2, or Windows Server 2012 as the guest operating system

windows server 2016 hyper-v -- requirements

bit disappointed that I could not install server 2016 with hyper-v role on my old hardware

it is that SLAT is required for Server 2016 hyper-v, but that is not a server 2012 R2 requirement

differences between AAD and AD DS -- Azure AD and traditional on-premise AD DS

differences between AAD and AD DS
- no support for Group policy settings
- no OU or computer objects
- no support for forests ( rely on federation to extend scope)

- no forest AD trust

cisco dcloud is very interesting -- kind of a nice demo setup play ground

have trialed


Cisco ASA with FirePOWER for SMB Overview v1

Cisco ASA with FirePOWER for SMB Integrated Threat Defense v1

If I integrate the firepower with Fightsite online

then the firepower tab will disappear from the CISCO ASA, then click the link to goto the cloud

funny as a sales guy I can still open ebay (supposed to be blocked)

windows 2016 is here --- with not much fanfare

https://blogs.technet.microsoft.com/hybridcloud/2016/09/26/announcing-the-launch-of-windows-server-2016/?MC=WinServer&MC=DevOps&MC=SysMagSof&MC=EntMobile&MC=MSAzure

here is the Microsoft announcement

  • Advanced Multi-layer Security: Nearly every morning when I read the news, I see a new headline about a security breach. Attacks have become more sophisticated, so organizations must respond with a more sophisticated environment that presents new layers of defense at every level of potential compromise. As the operating system that runs mission-critical applications and databases, Windows Server can play a strategic role in an organization’s security arsenal. Windows Server 2016 gives IT the power to help prevent attacks and detect suspicious activity with new features to control privileged access, protect virtual machines and harden the platform against emerging threats. Learn more about the new security features.
  • Software-defined Datacenter: Many people don’t realize that our Azure public cloud is actually one of my Windows Server customers. This means they use Windows Server and Hyper-V at a massive scale to deliver some of the most efficient datacenters in the world. Not every organization needs this type of scale, but every organization can definitely benefit from the new models of cloud efficiency. We worked hard to build that into this release so every customer can benefit. As a result, Windows Server 2016 delivers a more flexible and cost-efficient operating system for any datacenter, using software-defined compute, storage and network features inspired by Azure. Learn more about the new software-defined datacenter features.
  • Cloud-ready Application Platform: Applications are at the heart of every organization and its ability to serve customers and compete effectively for their loyalty. As the digital transformation accelerates in every organization, nearly every application needs to transition or transform. Windows Server 2016 delivers new ways to deploy and run both existing and cloud-native applications – whether on-premises or in Microsoft Azure – using new capabilities such as Windows Server Containers and the lightweight Nano Server deployment option. And to make life easier for developers, today we announced with Docker a new agreement that will make the Commercially Supported Docker Engine (CS Docker Engine) available to Windows Server 2016 customers at no additional cost. Learn more about the new application platform features.

my weekend rescue series cotinues -- this time -recover my own windows 10 enterprise preview

my weekend rescue series cotinues -- this time -recover my own windows 10 enterprise preview

I am an updating freak --- I updated my w10 insider preview to the lastest version, did a reboot
still good

a few hours later , I did a shutdown , I know outlook open, some notepads open, I did the shutdown anyway

then I am trying to get a cisco dcloud url .... to my horror , my HP notebook failed to start ... blue screen of death

Recovery

Your PC / device need be repaired

the boot configuration file ....

file: \boot\bcd

error code: 0x0000034

you need revovery tools

its w10, no more F8 to enter safe mode any more

so I have to download W10 enterprise preview from MS website

burn to usb pen drive

I tried start up recovery , no luck

then I did
https://support.microsoft.com/en-nz/kb/2004518

Method 2: Rebuild the BCD store by using the Bootrec.exe tool
If the previous method does not resolve the problem, you can rebuild the BCD store by using the Bootrec.exe tool in the Windows Recovery Environment.
Determine the partition where \boot\bcd file is located.
Notice that the boot\BCD file may not be on the C: partition but on a separate system partition.
(OEM's are unlikely to assign a volume letter to the system partition.)
If the Bootrec.exe tool cannot locate any missing Windows installations, you must remove the BCD store, and then you must re-create it. To do this, type the following commands in the order in which they are presented. Press ENTER after each command.
  • Bcdedit /export C:\BCD_Backup
  • ren c:\boot\bcd bcd.old
  • Bootrec /rebuildbcd
that saved my weekend

btw: I tried a BCD repair tool, not wroking either

probably due to HP original hard drive put the bcd atcitve partition on the 1GB system partition, i,e diferent from the windows partition
