Windows 10 Technical Preview bug

On 8.1 just installed 10. On first start everything was ok... it was until restarted... . When tried to login again everything on laptop display was black... In the bottom right part was language bar, that contains only help button...
Best wishes,
Ivan Spahiyski

It is highly recommended when installing Windows 10 Technical Preview to ensure that all devices are fully up-to-date with the latest drivers from the system or device manufacturer. Please update the video driver to see if the issue appears with the latest
drivers installed.

Windows 10 Technical Preview 10041, Firefox Nightly x64 most current, can launch, can't access settings, cannot place cursor in URL box

Have Windows 10 Technical Preview build 10041, Firefox Nightly x64 39.0a1 most current. Firefox will launch, but when browser appears no input to screen possible. Can't access settings, can't place cursor in URL box. Tried compatibility modes with no success. I may not have used this browser on Thursday, March 26, but it was working without issue on Wednesday, March 25. My speculation would be that one of the last two nightly updates broke this. This question posted from Chrome as Firefox not operating.

hello, that appears to be a known bug that's being worked on ([https://bugzilla.mozilla.org/show_bug.cgi?id=1147953 bug #1147953]).
please also note that as long as windows 10 is in it's pre-release preview state and there are still changes to the core platform, it will not be fully supported by firefox and things are bound to go wrong on occasion.

Windows 10 Technical Preview: Windows Defender

Hi,
I have recently come into an issue with the Windows 10 Technical Preview
I have Disabled Windows Defender through the program and i now want to turn it back on.
When I go to the control panel and press turn on now it does nothing. I have checked the registry and the values DisableAntiSpyware and DisableAntiVirus are set to 1 when I try to change these values to 0 it prompts me with: Error writing Value's new contents.
I have tried this on 13 computers and the problem is there
The version for these computers was 9860 through 9879
I believe this to be a Windows error
Thank you,
Microsoft Guru

I briefly had the same (or similar) issue. On the "Home" tab of the Defender interface, the "Turn On" button refused to work, citing the error about the Defender service being off (but both were, in fact, on.) The "fix"
was easy enough, though...instead of from the Home tab, I went to the "Settings'' tab and from there simply checked the box and hit "OK/Apply"...and bingo...the problem disappeared and Defender successfully restarted.
IMO, it's a UI bug in Defender--a small one that I would never have noticed at all except that I turned Defender off to correctly apply build 9860 (as it would fail to install otherwise), and discovered the bug upon my attempts to restart Defender after
9860 installed. 9879 installed, however, without my having to first deactivate Defender's real-time (actually, I forgot about it...;))
That was the very first time I've had to turn off Defender's real-time in order to successfully install a program...but Win10 is a beta, and so such things are par for the course. What counts is not that they happen, but rather that we resolve them,
eh?...;)

[Forum FAQ] How to show Windows Update in Control Panel in Clean Installation of Windows 10 Technical Preview Build 9926

Scenario
If you performed a clean installation of the new Windows 10 Technical Preview Build 9926, you would find Windows Update is only available in
Settings and is hidden in Control Panel by default. However, Windows Update is still available in Control Panel if it is an upgrade version of Windows 10 Technical Preview Build 9926.
Solution
After the comparison of the two different version, the differences is the following registry:
HKLM\SOFTWARE\Microsoft\WindowsUpdate\UX\IsConvergedUpdateStackEnabled
In clean installation version:
In upgrade version:
The method to make Windows Update show in Control Panel in the clean installation of Windows 10 Technical Preview Build 9926:
Edit the REG_DWORD value of IsConvergedUpdateStackEnabled from 1 to 0.

We’ve seen a few forum posts talking about changing registry keys to alter the update experience we shipped in Technical Preview build 9926. There are a couple of reasons that we don’t recommend doing things like that.
First, the default experience is what we’ve tested across not just the Windows 10 team, but across all of Microsoft before we released it to you. That doesn’t mean that you won’t still find bugs, but it’s definitely the code that’s been most thoroughly
tested. Changing things back to older versions is risky because the combination of those old settings with the rest of Windows 10 is not something that’s been validated or supported, so we can’t predict the side effects. It’s possible that changing registry
settings related to update could cause a machine to no longer be able to get new updates or Technical Preview builds.
The other reason to avoid changing the default update experience is that a lot of update-related code is actually being re-written in order to scale across the variety of different device types Windows 10 will support. Since Technical Previews are
a work-in-progress, some code that may still be in build 9926 won’t actually ship in the final version of Windows 10 that we provide to all our customers, so trying to re-enable that code temporarily won’t provide a way to accurately assess Windows 10’s update
capabilities.
We want to hear your feedback! We’re sharing Technical Preview releases early so we can understand exactly how customers are using our software and make sure we are designing our experiences to address those scenarios. The more
specific the feedback, the more helpful it is for us – saying “I hate the new Windows Update UI” isn’t very useful, but when we see “I need to be able to tell Windows Update to grab updates from WU itself and not from my internal corporate server, so the new
Windows Update UI is painful for me”, we can actually understand what changes we could make to solve those specific problems. We can’t promise to fix everything that everyone asks for – and sometimes what one customer wants is exactly what another customer
doesn’t want – but the more you can help us understand why you want something changed, the better we can try to meet those needs.
Thanks for listening, and we look forward to hearing your responses.

About the error: "The account is not authorized to login from this station" when you access NAS devices from Windows 10 Technical Preview (build 9926)

Scenario:
With the release of Windows 10 Technical Preview (build 9926), some users may encounter an error message of “The account is not authorized to login from this station” when trying to access remote files saved in NAS storage. In
addition, the following error log may also be found via Event Viewer:
Rejected an insecure guest logon.
This event indicates that the server attempted to log the user on as an unauthenticated guest but was denied by the client. Guest logons do not support standard security features such as signing and encryption. As a result,
guest logons are vulnerable to man-in-the-middle attacks that can expose sensitive data on the network. Windows disables insecure guest logons by default. Microsoft does not recommend enabling insecure guest logons.
Background:
The error message is due to a change we made in Windows 10 Technical Preview (build 9926) which is related to security and remote file access that may affect you.
Previously, remote file access includes a way of connecting to a file server without a username and password, which was termed as “guest access”.
With guest access authentication, the user does not need to send a user name or password.
The security change is intended to address a weakness when using guest access. While the server may be fine not distinguishing among clients for files (and, you can imagine in the home scenario that it doesn’t
matter to you which of your family members is looking at the shared folder of pictures from your last vacation), this can actually put you at risk elsewhere. Without an account and password, the client doesn’t end up with a secure connection to the server.
A malicious server can put itself in the middle (also known as the Man-In-The-Middle attack), and trick the client into sending files or accepting malicious data. This is not necessarily a big concern in your home, but can be an issue when you take your
laptop to your local coffee shop and someone there is lurking, ready to compromise your automatic connections to a server that you can’t verify. Or when your child goes back to the dorm at the university. The change we made removes the ability to connect
to NAS devices with guest access, but the error message which is shown in build 9926 does not clearly explain what happened. We are working on a better experience for the final product which will help people who are in this situation.
As a Windows Insider you’re seeing our work in progress; we’re sorry for any inconvenience it may have caused.
Suggestion:
You may see some workarounds (eg. making a registry change restores your ability to connect with guest access).
We do NOT recommend making that change as it leaves you vulnerable to the kinds of attacks this change was meant to protect you from.
The recommended solution is to add an explicit account and password on your NAS device, and use that for the connections. It is a one-time inconvenience,
but the long term benefits are worthwhile. If you are having trouble configuring your system, send us your feedback via the Feedback App and post your information here so we can document additional affected scenarios.

I can't install Windows 10 Technical Preview in Dell Inspiron M5030

Hello everyone.
I have a big problem when installing the Windows 10 Technical Preview, everything goes well until the moment that says "getting devices ready XX%" after this the screen turns black, which I had already happened when installing Windows 8.1 . I have
Windows 8 Pro and gave me problems to install, but with these two versions of Windows I always throws this error. Right now what interests me is to have installed Windows 10 Technical Preview to be developing some applications we have had in mind
a few colleagues and I, but I have not managed to install it. I have to turn the laptop to use it again, and when you start telling me "restoring your previous version of windows" And once again normally on, send me a message saying "We Could
not install Windows 10 Technical Preview" and send me the error code 0xC1900101 - 0x30018.
HELP!
I urgently need to have installed this version of windows.

Hi Domeck98,
This kind of issue is mostly caused by the driver compatibility issue during upgrade.
And it’s hard to find the culprit from installation log. The error code is sent by the setupact.log.
For a better method to test the 9879 build, it is recommended to perform a clean install in your case:
Here is the link to download the 9879 build ISO.

We can burn it to DVD media or use it create bootable USB drive.

No, Windows 10 Technical Preview is for testing and evaluation only , in addition it is not the final version of Windows and it is strongly recommended to use it for testing
not production.

Hi zelgay,
This is my result:
From your error code, it seems this is relate to your windows update, please use following command to fix corrupted files:
DISM.exe /Online /Cleanup-image /Restorehealth
In the meantime, you can delete temporary update files in the SoftwareDistribution folder:
Stop Windows Update service.
Open File Explorer.
Double-click the local hard disk where Windows is installed, typically drive C.
Double-click the Windows folder, and then double-click the
SoftwareDistribution folder.
Double-click the DataStore folder to open it, and then delete all files and folders in the folder.
Note If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
Click the Back button. In the SoftwareDistribution folder, double-click the
Download folder to open it, and then delete all files in the folder.
Restart Windows Update service.

Windows Server Technical Preview - RDS - RemoteFX 3D

Hi Windows Server Team,
I am having an issue with the Windows Server Tech Preview and Remotefx 3D. I installed the RDS role and have it all configured with no problems. I loaded a VM of Windows 10 Enterprise Tech Preview. It works fine, however when I activate the RemoteFX 3D on
that virtual machine. It then just shows a black screen in my Hyper-V Manager and just stays hung on the black screen. I have been working with RDS and RemoteFX 3D since the Windows 2008 R2 days and have never had this problem at all. When I try to Shut down
the VM it stays hung when I try to Turn Off the VM it stays hung. I am forced to reboot the server and when it comes back up it still just shows a Black screen for the Windows 10 Enterprise VM with RemoteFX 3D turned on. I really wanted and was interested
in testing the new OpenGL features and other ehancements that have been mentioned with this version of RDS and remotefx 3d. I also noticed that Gen 2 VM's now also support the RemoteFX 3D features and even tried to create a Windows 10 Enterprise as a
Gen 2 VM but I have the same problem. My server is a Dell PowerEdge R720. Thanks and I look forward to your reply and can hopefully get this working.
Regards,
Robi Rodriguez

Hi,
Thank you for posting in Windows Server Forum.
Initially we need to check whether the device is supported for latest version of features available. To use new feature available with Windows Serer Technical Preview we need to see that device supports the latest available OS. Please go through
this article for information. You can contact Dell for further information whether it
still have any updates for Windows Server Technical Preview.
Hope it helps!
Thanks.

If you're running 9926 then you're not installing the correct version. If
you expand the Details section you'll see that version was published last
October. You'll need this one, which was published in at the end of
January:

PC Settings application in Windows Server Technical Preview

The PC Settings app in Windows Server Technical Preview would not start with a message "Immersive control panel did not start". Does anybody else have a similar problem and what might be the cause of it?
Vladimir Shipitsyn

I accidentally checked the PC settings app today and surprisingly found it perfectly working. I do not know what caused it to start working since Microsoft did not offer any updates for Windows Server TP in February (maybe it was a matter of an
earlier update?), however, I was able to set the account picture and the lock screen as well as some other settings. I did not find there though any provision for build updates like in Windows 10 TP, only regular Windows Update menu.
Vladimir Shipitsyn
Hello,
where did you see PC Settings? On my Test machine it is removed complete from the Start Menu and also when using WINDOWS+C where it was possible at the beginning.
