This update applies to Windows 10 Version 1703

October 10, 2017—KB4041676 (OS Build 15063.674)

This update should apply via Windows Update – If it does not, or you need to install this manually here is the direct download link.

Improvements and fixes

This update includes quality improvements. No new operating system features are being introduced in this update. Key changes include:

  • Addressed issue where some UWP and Centennial apps show a gray icon and display the error message “This app can’t open” on launch.
  • Addressed reliability issue that causes the AppReadiness service to stop working.
  • Addressed issue where applications that use the Silverlight map stack stop working.
  • Addressed issue where VSync prevents devices from entering Panel Self Refresh mode, which can lead to reduced battery life.
  • Addressed issue where user customizations (like pinned tiles) made to an enforced partial Start layout are lost when upgrading to Windows 10 1703.
  • Addressed issue where the Universal CRT caused the linker (link.exe) to stop working for large projects.
  • Addressed issue that prevents Windows Error Reporting from saving error reports in a temporary folder that is recreated with incorrect permissions. Instead, the temporary folder is inadvertently deleted.
  • Addressed issue where the MSMQ performance counter (MSMQ Queue) may not populate queue instances when the server hosts a clustered MSMQ role.
  • Addressed issue with the token broker where it was leaking a token that caused sessions to remain allocated after logoff.
  • Addressed issue where Personal Identity Verification (PIV) smart card PINs are not cached on a per-application basis. This caused users to see the PIN prompt multiple times in a short time period; normally, the PIN prompt only displays once.
  • Addressed issue where using the Cipher.exe /u tool to update Data Recovery Agent (DRA) encryption keys fails unless user certification encryption already exists on the machine.
  • Addressed issue where using AppLocker to block a Modern app fails. This issue occurs only with Modern apps that come pre-installed with Windows.
  • Addressed issue with form submissions in Internet Explorer.
  • Addressed issue with the rendering of a graphics element in Internet Explorer.
  • Addressed issue that prevents an element from receiving focus in Internet Explorer.
  • Addressed issue with the docking and undocking of Internet Explorer windows.
  • Addressed issue caused by a pop-up window in Internet Explorer.
  • Addressed issue where a Vendor API deleted data unexpectedly.

  • Addressed issue where MDM USB restrictions did not disable the USB port as expected.
  • Addressed issue where creating an iSCSI session on a new OS installation may result in the “Initiator instance does not exist” error when attempting to connect to a target.
  • Addressed issue where connecting to RDS applications published using Azure App Proxy fails. The error message is, “Your computer can’t connect to the Remote Desktop Gateway server. Contact your network administrator for assistance”. The error can occur when the RDP cookie size limit is exceeded. This update increased the size of the RDP cookie limit.
  • Addressed issue where USBHUB.SYS randomly causes memory corruption that results in random system crashes that are extremely difficult to diagnose.
  • Addressed issue that affects the download of some games from the Windows Store during the pre-order phase. Download fails with the error code 0x80070005, and the device attempts to restart the download from the beginning.
  • Addressed issue where the ServerSecurityDescriptor registry value does not migrate when you upgrade to Windows 10 1703. As a result, users might not be able to add a printer using the Citrix Print Manager service. Additionally, they might not be able to print to a client redirected printer, a Citrix universal print driver, or a network printer driver using the Citrix universal print driver.
  • Security updates to Microsoft Windows Search Component, Windows kernel-mode drivers, Microsoft Graphics Component, Internet Explorer, Windows kernel, Microsoft Edge, Windows Authentication, Windows TPM, Device Guard, Windows Wireless Networking, Windows Storage and Filesystems, Microsoft Windows DNS, Microsoft Scripting Engine, Windows Server, Windows Subsystem for Linux, Microsoft JET Database Engine, and the Windows SMB Server.

What Is s0.2mdn.net Does This Site Host Malware ?

The domain 2mdn.net and s0.2mdn.net are owned and used by Google.  It is used for Google Ads – Lookup of domain owner here 

When you do a Google search for this domain a lot of stuff that shows up that seems to relate to malware (see image below) With topics like “How to delete S0.2mdn.net pop-up completely from your system” and “How to delete S0.2mdn.net pop-up completely from your system” and “s0.2mdn.net Removal Technique” and “How to Remove s0.2mdn.net (Chrome/Edge/Firefox)” the list goes on…

The above examples take you to websites that want you to download (fake) software that will remove this, or ask you to run a tool to scan your PC for this, and any other random stuff you search for, they seem to have a fix for it !  Do not visit such sites or click any links on them, they will probably infect your PC with malware or a virus.

This site is NOT malware, it is just used to show adverts.  It is highly unlikely that you have been infected by malware from a Google Adsense advert.

You may also find lots of reference to this in your proxy server or firewall logs.  This is because most website host Google Ads and therefore there is a lot of requests to this domain.  It will probably appear in your top sites lists, alongside other ad and tracking code used by Google.

The site used to be owned by DoubleClick ad network, but Google now owns this.

If you suspect you have a virus or malware on your computer, do not click and links on random websites when searching for information, contact a computer repair specialist (like ourselves) to check and remove any issues.

Windows Blue Screen Error STOP 0x0000001E KMODE_EXCEPTION_NOT_HANDLED

This post provides information how to repair and troubleshoot the Microsoft Windows Blue Screen error “STOP 0x0000001E: KMODE_EXCEPTION_NOT_HANDLED”.

This issue occurs because of an NTFS file system memory leak issue. Specifically, when an application opens a file that has an oplock on it for modification in a transaction, NTFS will break the oplock and will leak nonpaged pool memory. This causes excessive memory usage and memory allocation failures.

If you have a Microsoft Windows blue screen error 0x0000001E, you may be able to gain some basic information on the code alone. For additional information, refer to Microsoft Support Article: How to troubleshoot a “Stop error code 0x0000001E KMODE_EXCEPTION_NOT_HANDLED)” error message. Troubleshooting from the Microsoft support site is re-published here for your convenience:

  1. Try to replace the driver that is identified in the STOP error message, either with a known good copy from your installation media, or with an updated version from the manufacturer.
  2. Disable the driver that is identified in the STOP error message or any newly installed drivers.
  3. Verify that any new hardware or software is properly installed. Disconnect the new hardware or replace it to see if this resolves the issue.
  4. If you have a video driver that was not supplied with the operating system, try switching to the standard VGA driver or a driver that is compatible with the operating system
  5. View the following Hardware Compatibility Matrix from the Microsoft web site to verify that all your hardware and drivers are compatible with the operating system.
  6. Run any system diagnostics that are supplied by your computer manufacturer, especially a RAM check. If this is a new installation of the hardware or software, contact the manufacturer for any requires updates for drivers or firmware.
  7. Disable all filter drivers, such as remote control software, antivirus programs, backup programs, and so on.

Included below are generic troubleshooting steps. Not every Blue Screen error requires an Operating System reinstall. In fact most can be repaired. These steps are not specific to the actual code and may not be necessary for every Blue Screen error.




Solution:

To isolate the cause, run PSA/ePSA diagnostics.
For detailed instructions on running PSA/ePSA diagnostics, refer to Dell Knowledge Base Article: Run Built-In Diagnostics for Your System.

Included below are generic troubleshooting steps. Not every Blue Screen error requires an Operating System reinstall. In fact most can be repaired. These steps are not specific to the actual code and may not be necessary for every Blue Screen error.

  • If diagnostics fail, access the Dell Interactive Support Agent and search the error codes to determine which part is causing the error.
  • If diagnostics pass, identify when the Windows Blue Screen occurs.
    • Pre-boot: To determine a faulty part, isolate the memory by connecting 1 module at a time, and isolate the hard disk by connecting a known good hard disk to the system until the faulty part is discovered.
    • Pre-logon: Boot into Safe Mode and disable all Startup entries. Isolate 1 Startup entry at a time until you find the causing agent.
    • Intermittent / post logon: Collect the minidump files by navigating to C:\windows\minidump and analyzing the minidump files using a tool called BlueScreenView developed by Nirsoft. You can also use Windbg and use the link to Dell.com to set up the debug. Identify the causing agent and reinstall the appropriate driver or application. If the issue still persists, it may be necessary to perform a windows reinstallation.

Error 0x80070057-00000000-00000000 Outlook Meeting Request

When you try to send a meeting request from Outlook you get the following error :

Your message did not reach some or all of the intended recipients.

Subject:    Test Message

 

Sent: 29/03/2012 13:51

 

The following recipient(s) cannot be reached:

Smith John (Test) on 29/03/2012 13:51

This message could not be sent. Try sending the message again later, or contact your network administrator.  Error is [0x80070057-00000000-00000000].

To fix this you need to ensure that the sender of the request has picked the address from the global address book or if that does not resolve the issue try a /cleanprofile or /cleanfreebusy and this should resolve the issue.  I have seen this error on Outlook 2003 and 2007 so it may be on other version also.
