Windows 10: How to turn off VBS on Window 11 Home Edition for Cisco Modeling Labs VMs

Edward Rothwell · Dec 13, 2023

Hello,I have a Samsung Galaxy Book 3 Ultra with Windows Home Edition and I can't after surfing the whole INTERNET find a way to successfully turn off VBS, in order to use VMs inside of CML. The KVM/VMX in CML has a red X. Also, I am using VMware Workstation 17 non-commercial use only. I selected and deselected the "Virtualize Intel VT-x/EPT or AMA-V/RVI" in VMware 17 - and still I get the red XI tried all the solutions that I could find and none of them are working.Tried to turn of Virtualized in Windows Features, Local Group Policy Editor, Regedit and there is no trace of it.Any assis

How to factory reset Cisco 1700 Router

Hopefully I can help you here....its a very common thing to happen.

First, I take it you dont know the passwords for console access or telnet/ssh?

I will assume that these devices belong to you.

step 1. Plug a cisco console cable into a serial port on your pc
step 2. Plug other end into Cisco console port
step 3. Using hyperterm or putty or similar connect to the serial port
step 4. boot router, and make sure you clearly can see the output (this confirms you have good serial comms)
step 5. if this fails, adjust the comm port settings (9600, 8,1,n are the default)
step 6. now you have to do the only hard part...send the break command:

Break command list: Break Commands

Go down the list and match your OS and SW and try the sequence suggested.

If this fails several times do what I do: Install putty (free) and then to send a break so you can get into rommom just hit "ctrl-a b".

Problem activating Windows 11 after switching VMs

Hi there,

I purchased Windows 11 Home a couple of months ago and installed it on a VirtualBox VM. But VirtualBox was crashing quite a bit so I deactivated Windows 11 using the following commands:

slmgr /upk

slmgr /cpky

(as suggested on Redirecting ) and then installed it on a VMWare VM. Problem is, I can't activate Windows on the new VM even though it was deactivated on the old VM. I tried the recommended Troubleshooting Wizard solutions to no available and I couldn't find a Microsoft email address or support number, so I am posting here. Can anyone suggest how to contact Microsoft about this activation issue?

Thanks,

Darryl

PS: I have already deleted the old VM so I can't log back onto it.

Credential Guard lab companion

If you have heard about Credential Guard in Windows Server 2016 (and in Windows 10), but do not have an environment to try it out, here is a lab environment we built for you to play.

Lab access

The link will lead you to a sign up page, after that, you will see the following labs listed for Windows Server 2016:

Windows Server 2016 labs

There are 3 exercises in the “Implementing Breach Resistance Security in Windows Server 2016”:

Credential Guard

Remote Credential Guard

Device Guard

This blogpost will walk you through the Credential Guard lab details.

After click on the link of Breach Resistance lab, you be required to sign in and then you can launch the lab:

Sign-in

Launch page

It takes a few minutes to create the VMs, and once it has done, you will see the following machines prepared:

Initialize

DC: domain controller, which is not used for this exercise.

SRV01 and SRV02: both are Windows Server 2016, and used for the lab exercise.

Lab exercise – Explained

The steps are listed in the Content section:

Content

This lab is structured to cover the following in sequence:

Understand how attackers can use the hash in memory to gain access to domain controllers

Configure Credential Guard

Verify the hash in memory is protected using Credential Guard

You can follow the steps listed under the content section to complete the lab, the intent of the blog, is to break the procedures into groups, to help you understand the exercise better.

Prep the hash

Lsass.exe is the process which handles user logon, it stores the user credential information in its memory. The memory is cleared when the machine starts up. In this lab environment, all the virtual machines start at the time lab launches, when you logon to the machine, you will only have the logon user credential information in memory. In order to demonstrate an attacker gaining user access using other account’s hash, the first part of the lab is to simulate a server which has been running for a while, different users had remotely or locally connected to it, therefore, lsass memory stored many different user credential information.
This is accomplished by step 1-8.

Retrieving credential hash

Mimikatz is a popular tool for retrieving lsass memory information. The tool has been copied to the lab machines, step 9-13 walk you through the process of dumping lsass memory using Mimikatz.

Pass the Hash

Pass the hash is a hacking technique that allows an attacker to authenticate by using the underlying NTLM, instead of specifying the user password. In step 14 to 24, you will extract LabAdmin hash from lsass using Mimikatz, and use the hash to open a PowerShell console, and perform a couple of operations using the LabAdmin privilege:

Add a user to the domain admin group

Open remote PowerShell connection to a domain controller

Both operations could not be performed by the logon user. But using the hash of the LabAdmin, an attacker will be able to do it using the information retrieve from Lsass memory.

Configure and verify Credential Guard

Step 25 to 36 illustrate the steps to configure credential guard, then verify its status using msinfo32.exe and PowerShell.

Step 37 to 43 goes further to use Mimikatz to show the hash in Lsass is now encrypted using Credential Guard.

More info

The exercise illustrated the benefit of Credential Guard in Windows Server 2016 as well as Windows 10. For more information, you can find here.
