Windows 10 Technical Preview Issues

Windows 10 Technical Preview
installed windows 10 tech preview for PC ( UK )
after installing the tech preview for PC in the latest VM Workstation I was liking what I was seeing However I had to Uninstall as Most of the time it was either to slow or unresponsive to use even giving it 2 gig ram 60 gig of hard drive space nothing else
installed just what it came with and it was hammering the CPU and Memory was surprised really Considering I have used beta's and tech previews before and they were all ok apart from Windows 10 I still believe it was the VM's fault for the Performance issues,
Never Mind Here's to the stable Release Sometime this Year.

Hi P.W,
Thank you for your feedback.
I am also testing Windows 10 using VMs, and it works good, or we may say most of the times.
Sometimes it responds slowly, and after the upgrade to a newer version or some Windows Update, it will get back to normal.
There are also some known issues listed on Windows Blog when new versions are released, you may check the information at hte site below:

[Forum FAQ]Start Menu Scroll Issue in Windows 10 Technical Preview Build 9926

Scenario:
When upgrading to Window 10 Technical Preview Build 9926 from Windows 10 Technical Preview Build 9879, you may notice that on the start menu, when you move mouse to the right side, it won’t scroll until you click it.
Solution:
This is because the value of the key DWORD
MouseWheelRouting which is under
HKEY_CURRENT_USER\Control Panel\Desktop values changed to 0 after upgrade.
Note:
Before you make changes to a registry key or subkey, we recommend that you export, or make a backup copy, of the key or subkey.
Press Windows logo key +R to open Run, type
regedit, and then press Enter to open Registry Editor.
Navigate to the key HKEY_CURRENT_USER\Control Panel\Desktop.
On the right side, change the value of the DWORD MouseWheelRouting
to non-0 and non-1, for example 2, 3, which is set to 1 by default.
Exit Registry Editor.
Sign out and sign back.

same issue in build 10049.
It would help to be more specific in the symptom description. E.g. using Narrator may help. (Win-Enter). Does it say what you are "seeing" (or should be seeing)?
FWIW I think it is relatively easy to reproduce symptoms which are related to this thread's description using Narrator (Start Screen without Search bar, Search bar without Taskbar, or Search bar with Taskbar but without Start Menu
when the only time that the Search bar should appear is when the Start Menu is there, for example) so that could also help specify what your real symptom is. BTW there are horrendous delays when using Narrator.

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.
http://windows.microsoft.com/en-us/windows/preview-iso-update?os=win10
We can burn it to DVD media or use it create bootable USB drive.

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.

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 BSOD when running Lightroom

I have been running Lightroom on a PC with the Windows 10 Technical Preview. I have been experiencing frequent crashed (BSOD) but they're primarily when I'm running Lightroom. I've never had any problems with Lightroom on Windows 7,8, or 8.1, but now with Windows 10 something is wrong. I also rarely see any problems with Windows 10 when I'm NOT running Lightroom. It really seems like some issue with Lightroom and Windows 10.
I'm just curious if anyone else evaluating Windows 10 has run into problems with Lightroom.

I don't think you understand...
I'm not expressing frustration with either Lightroom or Windows 10...
I'm not using Windows 10 for anything critical. People like me sign up for things like Windows Insider and technical previews to help test the product in day-to-day situations to help make sure they work prior to final release. It's also an opportunity to evaluate the look and feel for the product. I realize that perhaps not all software companies do that, but thankfully, Microsoft does. The more people out there testing things like this, the better the chances that software will work as expected when it's released.
Of course, I have submitted feedback to Microsoft on what I have encountered, but I was also wondering if there are other Lightroom users who may have encountered similar problems or if I'm the only one.

Lync screen sharing doesn't work in Windows 10 Technical Preview (9879 Build)

Why Lync screen sharing doesn't work in Windows 10 Technical Preview?
It works well Windows 8.1, but why not in Windows 10?

Hi PriTeddy,
Thanks for your feedback.
As Paul Adare said, Microsoft has noticed such issue, they are listed in following blog:
http://blogs.windows.com/bloggingwindows/2014/11/12/new-build-available-to-the-windows-insider-program/
Some known problems:
As with the last build, you’re getting hot-off-the-presses code which means there are a few issues. We’ll be publishing WU updates shortly to fix the first two, but the remainder will not be fixed for 9879.
•In some cases you may get a black screen when trying to log-in or unlock. The only option is to hold the power button to hard reboot.
•You will be unable to connect to Distributed File System network locations.
•Some systems may see disk growth of 20GB+ due to driver install duplication. On systems with low disk space this can block setup and cause a rollback to the previous build.
•Skype calls will disconnect and Music will stop playing if those apps are minimized.
•There are several known issues with screen sharing with Lync.
Let’s wait for next builds.

Windows 10 Technical Preview Enterprise Build 9879 Product Key

Hi
Does the Windows 10 Technical Preview Enterprise 9879 uses the same product key as build 9841???

I would have been totally satisfied if the final release was B9860.
I have installed the TP on all my pc's. I have 3 desktops and a laptop that I did clean installs for on spare hard drives.
I also cloned the Windows 8.1 systems from each of them - and upgraded to Win 10 TP to see how it would handle the variety of applications I have on each.
One minor issue was that a diagnostic application I prefer to use - lost some of it's capability to display certain components like CPU specs.
The audio had been working exceptionally well up to B9860. Then I had one major issue on one of the desktops - when the audio stopped working right. Microphone audio was passed to the speaker output correctly - but NO audio
was passed from Windows Media Player or Winamp. But it did pass audio thru to the speakers from a music editing application which I use.
Even more strange was that when I moved that hard drive to another desktop which has similar motherboard - the audio works perfectly. Both have VIA audio devices.
I also installed Win10 TP Enterprise on a hard drive and had the same results as above when booted up on those two desktop pc's. Whatever evidence I could extract has been passed back to Microsoft.
On checking I find the Win10 TP and Enterprise use the same key.
Otherwise - as you say - Windows 10 is GREAT. So I can't wait for the final release.
btw: I have done about a dozen different installs and never had to enter the install key when installing any of the Win10 systems. I have the general Win10 TP B9841 ISO burned to a DVD and each install had to be upgraded to the next build available.
The Enterprise comes as B9879 and I burned that ISO to a USB3 Flash Drive. Much better performance - and re-usable. So I will not be using DVD's in future.

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?...;)
