Windows 10 – Cannot start Virtual machine because the hypervisor is not running

This post is just to fix if you cannot start a VM what was working previously perfect and suddenly it started to give Error

“Virtual machine [VM Name] could not be started because the hypervisor is not running”


I suggested running the following from an elevated command prompt: (Please run Command prompt as administrator)

bcdedit /set hypervisorlaunchtype auto

Shutdown the Computer , Unplug the Power code and wait for a while and switch on the computer.

Now try to start the VM

Additional info –


Second Level Address Translation is a technology introduced in both Intel and AMD flavors of processors. Both companies call their version of the technology different names, Intel’s version is called EPT(Extended Page Tables) and AMD calls theirs RVI (Rapid Virtualization Indexing). Intel introduced Extended Page Tables in its processors that were built on the Nehalem architecture, while AMD only introduced RVI in their third generation of Opteron processors codenamed Barcelona. Hyper-V uses this to perform more VM memory management functions and reduce the overhead of translating guest physical addresses to real physical addresses. By doing this, Hypervisor CPU time is significantly reduced, and more memory is saved for each VM.

How Do I Know If I Have SLAT?

Your system administrator does not allow the use of saved credentials to log on to the remote computer


If you’re a system administrator working with remote desktop a lot within a somewhat restrictive domain environment, you may be frustrated by the following message:

There are a few tutorials on the net that say to remove this you just need to go into Group Policy and disable ‘Do not allow passwords to be saved’, unfortunately that isn’t what this error message is related to. Instead, we need to change another part of Group Policy.

Hit Win+R to bring up the ‘Run’ dialog, enter ‘gpedit.msc’ and hit OK.

Run dialog with gpedit.msc

Go down the tree into Computer Configuration -> Administrative Templates -> System -> Credentials Delegation.

Group Policy -> Credentials Delegation

Now, you need to allow Allow delegating saved credentials and Allow delegating saved credentials with NTLM-only server authentication. For each, you’ll also need to allow a set list of servers that are explicitely allowed to save credentials, you can enter IP Addresses, Server hostnames, AD Domain name wildcards, or just any old wildcard. Since I wanted to be able to store credentials for everything, I just used a plain wildcard, and you can too!

Allow Delegating Saved Credentials with Wildcard

There we go, you’ll now automatically connect to your servers!

Cannot open this item. The text formatting command is not available. It may not be installed correctly. Install Microsoft Office Outlook again



When you try to open an email message in Microsoft Outlook 2013, Outlook 2010, or Outlook 2007, you receive the following error message:

Cannot open this item. The text formatting command is not available. It may not be installed correctly. Install Microsoft Outlook again.
Microsoft Solution for this avilable

Some say that computer problems happen at the worst times. I’m not sure that is true, but I won’t argue. Without warning, my Outlook email stopped working last week. I could receive email, but I couldn’t open any items. Instead, I saw an error message that read “Cannot open this item. The text formatting command is not available. It may not be installed correctly. Install Microsoft Office Outlook again.” Fortunately, my main email address runs in parallel so I wasn’t totally hosed.

For most of my Outlook email problems, I can work my way to a solution. This one had me stumped although I had some functionality running Outlook in safe mode.

To start Microsoft Outlook in safe mode,

  1. For Windows 7, click Start. For Windows 8 or Windows 8.1, press your Windows key and then the X key, then choose Run from the popup menu.
  2. Type Outlook /safe in the Run dialog box.

Prior to calling Microsoft Support, I did a query on the error message to see what solutions had been suggested. While I don’t know the cause of the problem, I found 3 suggestions that might solve the problem.

(For me Suggestion 3 worked)

Suggestion 1: Reinstall Microsoft Outlook.

If the developer offers a solution on an error message, that’s where I start. Let’s face it, they have the inside advantage. In my case, I recently installed some Windows patch files and thought they may have contributed to the problem.

Suggestion 2: Create a New Outlook Profile

From what I read, this procedure fixed the problem for many folks. This was the first thing the Microsoft technician suggested.  SlipStick has a good tutorial on this.

Like the first suggestion, this one didn’t fully resolve my problem. It appeared to work and then the error message reappeared. Again, I had to call Microsoft.

Suggestion 3: Close Outlook and Rename 4 .DAT files

The third time was a charm as the saying goes. This tech rep offered a different solution from his peers. In my case, this solution worked.

There were four .dat files that were renamed so the originals were still around if needed.

  • outcmd.dat
  • frmcache.dat
  • views.dat
  • extend.dat

When Outlook restarted, it created new versions of those files.

As a result of this fix, I did lose some custom view and toolbar settings, but I think it was worth the cost. It’s was much easier for me to recreate those settings than to be without my email. And yes, I’m still catching up on email inquiries if you sent me something.

Update Windows Defender even when Automatic Windows Updates is disabled in Windows 8/10

Windows Defender will not update its definitions, if Windows Updates is not set to Install updates automatically in Windows 10/8. If for some reason you have changed your settings and preferred to set any of the other three updating’s options, viz. Download updates but let me choose whether to install them, Check for updates but let me choose whether to download and install them or Never check for updates, your Windows Defender will not have the latest definitions, till such a time that you update them manually. This is because, Windows Defender and Windows Update in Windows 8 are  both dependent on the Windows Updates services.

This is not a recommended scenario, as one’s security software should be updated as soon as new definitions are available for download.

Update Windows Defender when Automatic Windows Updates is disabled

But you can set it so that Windows Defender will check for, download and install updates as soon as they are available, even if you have disabled Automatic Windows Updates.

To do so, open the Task Scheduler. You will find it under Administrative Tools in your Control Panel.


In the right pane, click on Create Basic Task. The Create Basic Task Wizard will open. Give the task a name and description and click on Next.


Select the frequency, viz Daily.


Set the Time at which the updating task should run.


Next select Start a program.




In the Program box, type “C:\Program Files\Windows Defender\MpCmdRun.exe”. MpCmdRun.exe is the executable file of Windows Defender that helps in carrying out common tasks like scanning, scheduling, updating, etc.

In the Add arguments box, type -SignatureUpdate. This is one of the available command line arguments for Windows Defender.


Having done this, review the details and click on Finish.


You will now be able to see the task in the Task Scheduler Library.

Now your Windows Defender will update itself, regularly, every day at the set time, although you may have disabled Automatic Windows Updates.

If you want Windows Defender to check for signature updates more than once every day, you will have to additionally do the following:

Open its Properties box and click on Triggers tab. Select the task and click on Edit.


Here check the Repeat task every and from the drop-down menu, select 1 hour. This will check for updates every hour. If you wish to check every 6 hours, simply change the figure from 1 to 6; it works!


Click OK/Apply and Exit.

When the task is run, a black CMD window will open momentarily and close down.

If you wish to run a silent update, instead of: C:\Program Files\Windows Defender\MpCmdRun.exe –SignatureUpdate you may use: C:\Program Files\Windows Defender\MSASCui.exe -Update.

Let us know how this works for you.

Analyze and clean the WinSXS folder

Please note that the commands will only work on Windows 8 or newer machines.

Here is what you need to do to analyze the WinSXS Folder:

  1. Tap on the Windows-key, type cmd.exe, hold down Shift and Ctrl, and hit the enter key on the keyboard. This opens an elevated command prompt on the system.
  2. Run the command dism.exe /Online /Cleanup-Image /AnalyzeComponentStore
  3. ceanup

The parameter /Online refers to the current installation, and /Cleanup-Image /AnaylzeComponentStore to analyzing the current component store of that installation (the WinSXS folder).


You can list all available commands using dism.exe /?, and subsequently dism.exe /Online /? and dism.exe /Online /Cleanup-Image /?.

The command runs a scan that takes a moment to complete. It echoes the Windows Explorer size and actual size to the command prompt window, and gives recommendations whether it makes sense to run a cleanup operation.


Windows runs a cleanup regularly using the Task Scheduler. You can check if that is the case on your machine in the following way:

  1. Tap on the Windows-key, type Task Scheduler and hit enter.
  2. Navigate to Task Scheduler (local) > Task Scheduler Library > Microsoft > Windows > Servicing > StartComponentCleanup

You can run the cleanup operation manually at any time using the following command using an elevated command prompt:

dism.exe /Online /Cleanup-Image /StartComponentCleanup

or for more

dism.exe /Online /Cleanup-Image /StartComponentCleanup /ResetBase


For service pack cleanup

dism.exe /Online /Cleanup-Image /spsuperseded /hidesp

Windows 10 Edge can’t be opened using the built-in administrator account


error Microsoft Edge can’t be opened using the Built-in Administrator account.  Sign in with a different account and try again.

In order to get around this message in your test environment and be able to use your Built-in Administrator account to navigate Edge, follow the following steps to get up and running.

  • Navigate to your local security policy on your Windows 10 workstation – You can do this by typing secpol.msc at a search/run/command prompt.
  • Under Local Policies/Security Options navigate to “User Account Control Admin Approval Mode for the Built-in Administrator account
  • Set the policy to Enabled




***Updated for Windows 10 Home Users***

For Windows 10 Home users, the local security policy editor doesn’t exist.  However, most of the policy changes that can be made using the policy editor can also be made using the registry.  I have not tested this on a Windows 10 Home system, however, changing this registry key should be the equivalent to enabling the policy above – See the UAC registry guide from Microsoft  Navigate to the following registry key:


  • Create a DWORD value if it doesn’t already exist called FilterAdministratorToken
  • Set the value to 1

Next we need to navigate to the registry and make an additional change:

  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\UIPI\
  • Change the Default string key to 0x00000001(1)Also, in addition to the above, make sure your User Account Control Setting is set to the third level from the bottom.  To get to UAC, go to your Windows 10 search and type uac.  It should come up as “Change User Account Control Settings“.

Finally, restart Windows and then you will be able to enjoy Edge under your Built-in Administrator account.



Can’t remove Hyper-V Backup Checkpoint/Snapshot from VM

Hyper-v 2012R2 uses checkpoints to aid the backup process of VM’s.

These checkpoints are created and deleted by the backup Process, the actual checkpoint can not be deleted using hyper-V manager GUI and will not show up in SCVMM at all.
Why you may ask? Well the reason is simple these checkpoints are actually differencing disks. Thats right the backup process creates a differecing disk, while this is basically the same as a checkpoint it can’t be deleted using any available GUI. It should actually be deleted by the backup Process.



Now you may notice that the icon is slighty different from that of a regular checkpoint, that is because this is a differencing disk. Running an inspection of the VHDX file will reveal this.




In this case a failed backup of the VM left the hindering checkpoint. The only way to deal with it is by using Powershell.

The following command will help you determine that a checkpoint is currently open on the VM:

Get-VMSnapshot -VMName VMNameWithCheckPoint -ComputerName HyperVServerName | fl

this returns the VM state

and his command will remove the checkpoint and merge the AVHDX file into it’s parent VHDX file.

Get-VMSnapshot -VMName VMNameWithCheckPoint -ComputerName HyperVServerName | Remove-VMSnapshot

Hope this helps if you find yourself in a similiar situation.

Slide to Shut Down a Windows 10 PC Like a Windows Phone

When Microsoft first released Windows 8, shutting it down was an annoying experience. However, it did get easier with Windows 8.1, and now there are several options you have now to shutdown, sleep, or hibernate in Windows 10.

Create Shortcut to Slide to Shutdown Windows 10 PCs

If you’re the owner of a Surface Pro, you can hold the power button down for a few seconds to get the slide to power off screen, but this creates a shortcut to do the same thing on a traditional laptop or desktop PC.

It’s just a matter of finding the file that’s hidden deep in the System32 folder. There are a couple of ways to do this. First, you could navigate there by going to C:\Windows\System32 and doing a search for sidletoshutdown.exe. Then send it to the desktop as a shortcut

Or, if you don’t want to navigate through the file system, here’s an easier way to do it. Right-click the desktop and select to create a new shortcut and enter the following path:






















There you go! Now when you tap or click the shortcut, you’ll see the following screen. Swipe it down to power off your PC. If you don’t swipe it down for 10 seconds, it will disappear.














How to setup BitLocker Encryption on Windows 8 / 8.1 without TPM

BitLocker is a full disk encryption software that comes standard with PCs running Windows 8 Pro or higher.


This document provides instructions for encrypting the hard drive without Trusted Platform Module (TPM – integrated security chip) present or enabled, and bypasses the USB flash drive encryption key requirement.

  1. From the Metro UI or the search box, type GPEDIT.MSC and press enter
  2. Open Computer Configuration =>
    Administrative Templates =>
    Windows Components =>
    BitLocker Drive Encryption =>
    Operating System Drives. From the right pane double-click “Require additional authentication at startup” and select “Enabled” and apply it. then run “gpupdate” from a command line.

Now you can enable Bitlocker without TPM
