Add features to Windows Technical Preview and asks for serial key, two different serial key but not work.

Hi,
Where did you get the product key? Online purchase is not available at this moment (my region is set to US), and please note that the product key for "Add feature" is not the same key for activating system.

Hyper-V Not Enabling on Build 10041 of the Windows Technical Preview

So I am running build 10041 of the Windows technical preview. I am not able to enable the Hyper-V Platform. Here are the steps:
Go to Control Panel -> Program and Features -> Turn Windows features on or off - > Select Hyper-V Platform Checkbox.
Windows will perform the install and request a restart.
While restarting, I will get the updating windows message and at about 95 % it gives me a message to the tune of "Unable to update windows" and it roll backs the changes and restarts. No Hyper-V.
Note that I can install the Hyper-V tools with out any issues just the Hyper-V Hypervisor and Hyper-V services will not install.
Anyone have any ideas?

Can't provide an answer, but I have the same problem. I'd originally let my 9926 build, with Hyper-V installed and working, upgrade to the 10041 build. After installation things seemed OK, until I noticed I had no network connections working. They were all
still there, but I had no network access and trying to view the properties of either my physical NIC or the Hyper-V switches just gave me an error.
I tried uninstalling Hyper-V, but after doing that Windows wouldn't boot at all. It'd begin to start up, get almost to the login screen, but then die and reboot. I decided a rebuild would probably be best anyway, so I chose to do a Refresh when it offered
me the advanced repair options.
The Refresh mostly went well, the PC is running better now with a clean install, but I'm now stuck in the same situation where the Hyper-V server won't install. It installs, reboots, gets part way through configuring, then claims to fail and backs it all
out again. No real diagnostic info presented as to why.

Windows To Go Device using Windows Technical Preview

I have successfully made a Windows To Go Device by the steps in this Technet forum post:
http://social.technet.microsoft.com/wiki/contents/articles/6991.windows-to-go-step-by-step.aspx
Note: I used a host machine running Windows Technical Preview already to make this device, since older versions (Windows 8/8.1) of DISM don't work for imaging Windows Technical Preview Installation.
Everything works fine. The device on which Windows To Go is running is a high-speed USB 3.0 HDD, so there is no significant performance difference. However, while updating to the new build 9860, the upgrade fails stating that you can't install it to a USB
Flash Drive.
Question 1) Does this problem has anything to do with the fact that I am NOT using the enterprise version of Windows Technical Preview, the only version which "technically" supports Windows To Go feature.
Question 2) My host machine (which I used to create Windows TP) has been updated to Build 9860. Should I use DISM to capture the image of this updated build and use it to image the WTG HDD device? Can I get detailed instructions on how to do this?

Hi G.One1,
In current time, there is no direct way to perform the upgrade, in both Native Boot to VHD and Windows To Go.
I was thinking a way to create a ISO file also, but the method would be a bit of complicated.
Here is my thought and steps.
First, if we update our Windows 10 Technical Preview for Enterprise to 9860 build, we would get a install.esd file, in Windows 8.1, here is a tool called update advisor, which would
convert the esd file to ISO file, but in Windows 10 Technical Preview, there is no such thing. So my thought is to use the install.esd to create an install.wim or bootable ISO file.
In my first thought, I want to sysprep an updated OS, but it failed without doubt. So, I choose to use Reset option. Install.esd would be recognized a compressed install.wim.
I copy the install.esd to a 9841 build OS, for example, I copy it to C:\RecoveryImage, and run
reagentc.exe /setosimage /path C:\RecoveryImage /target c:Windows /Index 1 , it cannot reset the Windows OS.
I use Reset option in 9860 build OS, when it is finished, run sysprep, it ran well, I can capture 9860 build wim file (WDS server capture or dism command). We rename it as install.wim.
Use the captured install.wim to set recovery image in 9841 build(copy install.wim to C:\RecoveryImage, and run
reagentc.exe /setosimage /path C:\RecoveryImage /target c:Windows /Index 1), 9841 build succeed upgrade to 9860 build via Reset and Refresh options.
For Windows To Go, Yes, you can use all Windows features with your Windows To Go workspace. The only currently unsupported features are using the Windows Recovery Environment and PC Reset &
Refresh. So this way is not appropriate in your situation. But here we use these steps can convert the install.esd to install.wim, and use reset and refresh option to upgrade current build.
Refresh would upgrade without losing setting and data. For your scenario, use dism to apply 9860 install.wim would be your option.

Officejet Pro K550 in Windows Technical Preview

The most recent update to Windows Technical Preview Build 9879 keeps stopping the print spooler when the Officejet Pro K550 is attached. It worked fine in the previous builds. Any ideas? I need to keep the USB cable disconnected until I want to print and then uninstall the printer each time or keep restarting the print spooler each time I want to print anything.
Thanks

Hi,
Try running Windows Update and check if any driver update is available, any drivers for the Technical Preview are only available from Microsoft Update servers.
If the issue persists, you will need to wait till an update will become available by microsoft, as a beta OS you are likley to experience this kind of issues, devices hasn't have been tested much, as well as the entire operating system.

Problem installing Windows Technical Preview build 9926

I am not able to install the Technical Preview on my computer. Everything looks fine and in the end it says "applying computer settings" and counts the percents before it reboots again.
During the boot it says evaluation build 9926. Then it says Restoring the old windows as it was before... I can't get this to work.
This is the windowsupdate.log file and the last attempt of installing at the end of the file. 21st of march.

Do you know that you can make an ISO to install 10041 and not have to install 9926?

Windows 10 to be free upgrade for first year for users of Windows Technical Preview?

Hello, in article I have read that will upgrade to Windows 10 users for free Win 7 & 8.1. I want to ask how it will be with those who use a version of the technical prewiev. I will also have a free update?
Thanks for the answers
Vít Repka

after 1 year if I do not want to purchase the upgrade, what happen to my computer, will go back to window 7?
What do you mean? You've already installed the Win 10 tech preview and you're wondering if it will automatically revert to the old software you were running some months ago after the trial period expires?
LOL
No.
Your expired Win 10 preview will pop up an "expired" notice and become less usable. Assuming it works like all other trial periods of Windows, it will limit its functionality and start shutting itself down every few hours. If you
want to revert it, it will be up to you to reinstall the old version. And then can anyone guarantee that it will reactivate properly?
Beyond that, and to the original point of this thread, what the mechanics will actually be for upgrading to Win 10 after its release on a system that was originally properly licensed for an earlier version of Windows are still not clear. We'd like
to hope that a product code for a legitimate licensed copy of an older version would just work to install Windows 10 from a DVD (ISO), but no doubt it will be more complicated than that. It shouldn't be, but it almost certainly will be.

Windows Technical Preview Build 9926 update

Hi,
I am trying to update my Windows 10 TP installation and it seems that it fails to download. I am behind a proxy server in the office with no way around it. Windows Update fails with error 0x80072ee2. What I have picked up is that I can
get the update list if I set a proxy server in BITS using "bitsadmin /util /setieproxy localsystem proxy1:port "bypass list". However bits fails to download the updates returning either Error or Transient_Error. Can you please assist
with this issue?
Regards,
Riaan
EDIT: I set proxy settings of each bits download job to PRECONFIG and the updates downloaded and installed.

Hi,
Did you set the proxy server via IE? Do you mean that the Windows Update Client ignore the proxy settings? To make Windows Update use the proxy setting, please execute the following command from cmd
Netsh winhttp import proxy source=ie
You can refer to this following KB for "how Windows Update finds proxy settings"
How the Windows Update client determines which proxy server to use to connect to the Windows Update Web site

"Couldn't Install Windows Technical Preview"

I'm on the original install and have seen the above message several times, followed by
"We couldn't update the system reserved partition."
I dual boot with Windows7 on a seperate hdd. And I use EasyBCD as the switcher at boot-up.
Any help would be appreciated. Thanks
Paul

Why or how did "system reserved partition" get involved ?
All my dual booting had been done using this method.......

WM_INPUT message no longer sent in Windows Technical Preview build 9879?

I had software that relied on the WM_INPUT message and it used to work with previous builds (and Win 8.1). I needed it for remapping a wireless keyboard's fn key to CTRL key (I was using an Autohotkey script which captures WM_INPUT).
But now looking at the messages sent when typing in the keyboard in a win32 app, only the button down and up are being sent. What changed? how to work around it?
Now I am using a hacky combination of user32.dll's SendInput and some methods from setupapi.dll to read/send the special key values.

Hello ibalhashim,
From your description, do you mean that after remapping the fb to ctrl, then only the button down and up are being sent?
If it is, please share us how you have remapped the keys and please test if removing the remapping operations, the WM_INPUT message would restore. This would help narrow down this issue to see if it is caused by the remapping operations or the win32 app.

Hi guys. I have a custom volume filter driver, which writes changes of volume to log file (placed in SystemVolumeInformation). It works fine in all versions of Windows. But it does not work for volume which contains hyper-v virtual machine, if this virtual
machine is configured for checkpoints and is running.
I use WdfRequestSend function, in callback check status like this
Status = WdfRequestGetStatus (Request);

"The computer started using Windows installation media." Installing windows 10 technical preview on virtual machine

The computer started using Windows installation media. Remove the installation media and restart your computer so that Windows starts normally. The, insert the installation media and restart the upgrade. (Do not
select |custom[advanced]| to perform an upgrade. |custom[advanced]| installs a new copy of Windows and deletes your programs and settings.)
That is the Compatibility report that I'm getting when trying to install onto parallels 10 Version 10.2.0 (28956) on my mid 2009 Macbook 13. This happens just after I click 'Install now' and accept the T&Cs.
I am selecting 'Upgrade: Install Windows and keep files, setting and applications'.
I am upgrading from the Windows Technical Preview Evaluation Copy. Build 9879.
I have updated my EFI and tried a few restarts and am booting from a CD. No luck yet.
Any help would be muchos appreciated.

Hi bitofagiggle,
I am not familiar with mac machines, based on what I know, there should be more settigns that need to be configured before the installation of Windows, I suggest you contact the manufacturer for further help regarding how to make Windows to upgrade smoothly.

Windows 10 Technical preview wifi problems

wifi button on windows technical preview does not respond.It shows grey color.But After a restart or logging in after some days the problem vanishes magically. but after some days the problem comes back. Is there a problem with the driver?
I use HP 630 notebook dual boot with windows 7 and technical preview. wifi works fine in windows 7.

Hi Aakshh,
I search for information about HP 630 Notebook PC, it seems there is no driver released for Windows 8.1.

Please Note: Since the website is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.
Generally, Windows 10 Technical Preview would work on the same hardware for Windows 8.1, in most situations, we can try the drivers for Windows 8.1 to install on Windows 10 Technical Preview.
From your description, it would be related to hardware driver. I would suggest your install the driver in Windows 7 compatibility mode to check the result.
