Tricking Windows 8 RT to display Flash

Windows RT’s both IE versions have built-in support for Adobe Flash but flash objects are only allowed from sites that are on the compatibility list of IE. This list is administered and updated by Microsoft.


If your site is not on the list you can have one site at a time (only one) that bypasses this check. This happened to me while trying to watch a movie from

This instruction can be found on MSDN: Here’s a short version:

You need to create a registry key

HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Flash\DebugDomain

where DebugDomain is a string value specifying the domain name as its data like the one I used:

Wioski 2.0 General availability!

As today is the general availability date on Windows 8 it’s more than convenient that my dearest project Wioski 2.0 is also available to help everyone with their brand new W8 slates and other form factor computers.

Wioski is a free SteadyState replacement that resets a Windows 7 or 8 machine to its original state as fast it normally takes the computer to reboot.


First question I got today morning was: Do Windows 8 Reset or Refresh functions compete with Wioski or even make it obsolete? Well it depends probably on who you ask but I’d say the don’t stand a chance! You can check the result on Wioski’s YouTube channel: but to sum it up here are the results:

- Windows 8 Reset = 22 minutes

- Windows 8 Refresh = 15 minutes

- Wioski reset = 28 seconds!


How often do we hear that Windows works for some time and then needs to be reinstalled – What if your Windows would reinstall every time it reboots – think about it! It doesn’t take longer than a normal reboot with Wioski Smile


I would personally like to thank Ronald Beekelaar for giving me a small but stepping on the Moon –type tip for Wioski. Ronald is an MVP in virtualization and I encourage everyone to follow him on Twitter!

As many of you know what Wioski is here’s a short list of what’s new in 2.0:

- Faster reset

- Support for Windows 8

- One installation media for Windows 7 and 8, for USB and DVD/ISO, and for both x86 and x64

- Ability to enable or disable the automatic reverting on every boot making it ideal for use in classrooms

- A lot of small fixes

Coreinfo for Hyper-V

Many students asked me about how to figure out if you have what it takes to run Client Hyper-V in Windows 8. As I mentioned in an earlier post Coreinfo.exe from Sysinternals tells you but what I didn’t provide was what to look for in the coreinfo output. I believe you can find what you need in this post:

Snip a menu

Sometimes your students tell you something that makes your life SOOO much easier. Like this time Anssi Järvenpää who told to read the help file Winking smile

I’ve used snipping tool a lot but I always changed to something else when needing to capture an open menu. No more Smile

Can I capture a snip of a menu, such as a shortcut menu or the Start menu?

Yes. Here's how to do it:

  1. Open Snipping Tool by clicking the Start button Picture of the Start button, clicking All Programs, clicking Accessories, and then clicking Snipping Tool.

  2. Press ESC, and then open the menu that you want to capture.


  4. Select the type of snip you want, and then capture the menu.


Thanks Anssi!

Logon time delay hunting example

Here’s a good example of learning some Windows Logon diagnostics. An “unknown” company with AD and Windows 7 clients.

After 15 minutes spent on diagnosing a really slow logon when using Direct Access I changed one setting in a Group Policy Preference item. The following picture shows that the logon time dropped from 400 seconds to under 200 seconds. The tools used were Event Viewer’s Group Policy log and Performance Toolkit. PT is part of the ADK which you can download here:

Customized AppLocker messages

Many people ask about customizing AppLocker to tell people why software was not allowed to run.

AppLocker only allows to have a support link to a website but it’s easy have your own on top. What you need to do is to create a Scheduled Task.

First open up the AppLocker logfile to attach a task to the error event:


Then tell the Task to display a message (you should remove the constraint of running without power cord so laptops can use this while without power):


And the result looks like this:

Upgrading WS2008R2 Standard to Enterprise

Already installed the standard version but need to get clustering etc working?

As I seem to try to find these instructions so often and they are spread around the place I decided to summarize them here:

  1. Start an administrative command prompt (UAC elevated)
  2. Run the following command:

DISM /online /Set-Edition:ServerEnterprise /productkey:AAAAA-BBBBB-CCCCC-DDDDD-EEEEE

You can try to use your own key but as it often doesn’t work you can use this general key: 489J6-VHDMP-X63PK-3K798-CPX3Y temporarily

After the restart (this takes a while) run the following commands to change your own key back:

  1. Type in slmgr.vbs -ckms (this clears any KMS entry you may have)
  2. Type slmgr.vbs -upk (this removes any product key installed)
  3. Type slmgr.vbs -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx (where the x’s is the new product key you want to use )
  4. Type slmgr.vbs -ato (this activates the server)

Running Windows To Go (how to survive with an Asus Zenbook)

I’ve tried to figure out how I would run my new Asus Zenbook and different OS’s on it.

First of all I wanted to test out how different disk drives perform on my Asus. I have the challenge that I used have a ten kg heavy Dell Inspriron M6400 with 640GB hard drive and 8 GB RAM. It also had an eSata interface and at least three USB ports.

Asus has one USB2 port and one USB3 port, 4GB of ram and 128GB SSD so I have lots of downsizing to be done. But hey, my Asus weights less than the power supply of my old Dell. First thing to shop for was absolutely a USB 3 hub and as USB 3 has bandwidth to play with this has been a very pleasant surprise.

I have to run my virtual machines from somewhere else as they will never fit on the 128GB SSD. So I started out testing different disks attached to the USB3. Here are the results:


So the results are quite obvious. While the Super Talent USB drive will be great for running Windows To Go and faster than conventional disks it lacks the power of the SSD disks. After playing around with different setups I ended up using the following combination:

Disk0 = 128GB Asus Internal disk for Windows 7 and software for daily use

Disk1 = USB3 casing with Samsung SSD for my mostly used VMs

Disk2 = 1TB 7200RPM USB3 drive for my ISO’s etc.

Disk3 = USB3 Key for running Windows8 (To Go)

“Disk4” = Home computer with reliable Internet connection and 16GB of RAM + lots of HDD.

I’m very happy with the performance especially for the VM’s running on the external SSD.

Next paycheck might change a few things though. The internal SSD would be nice to be at least 256GB and I would kill for 8GB of memory (Asus is said to have this available next summer so I’ll upgrade to that asap).

How to partition a USB disk in Windows

As Microsoft has published the manual instructions on how to create a USB stick for Windows To Go the only drawback is that there are only a handful of devices that these instructions can be used on. The problem is that the USB drive needs to show itself to the OS as a normal basic disk rather than a removable drive as Windows doesn’t allow partitioning a removable drive. You can do it with one partition but you lose the support for UEFI. I used to use a 7200RPM 500GB USB3.0 external drive but that’s not really pretty for demonstrations although it performs well and is totally suitable for running Windows 8.
You can get USB sticks partitioned following these instructions:
  • Install Windows 8 x86 on some machine
  • Download USB_LocalDisk here
  • On you Windows 8 machine extract the USB_LocalDisk to local harddrive
  • Insert the USB stick you want to use and find it in your Device Manager
  • Open the Details tab and find the Device Instance Path –value. Copy the value to the clipboard by right clicking it
  • Open the .inf file and replace the device_instance_id_goes_here with the string from your clipboard – Save the file
  • Go back to Device Manager, find your devices Driver tab and choose Update Driver
  • Browse for your driver
  • Choose Let me pick…
  • Choose Have disk and find your driver
  • Choose the default driver
