Microsoft Acknowledges Issues with Edge Developer Tools and SQL Connection in cumulative update KB4462933

In October 2018, Microsoft had release a cumulative update KB4462933 for Windows 10 V1803 users who had installed Windows 10 April 2018 update. This cumulative update released on 24th October lifted Windows 10 V1803 to build 17134376. It was a massive update with several important improvements and fixes. However, there were two main issues with this update that no one had noticed before, BornCity reports. One of the issues is the dysfunctional behavior of Edge Developer Tools and another is problems with SQL connections. These issues were also acknowledged by Microsoft on its support page for this update.

According to WindowsLatest, Microsoft had not originally acknowledged the presence of these issues but later quietly updated the document to confirm these two issues being faced with the latest update.

Issues with Edge Developers Tools

The update had promised to fix various bugs including the following:

  • Addresses an issue that sometimes prevents documents from appearing in the Microsoft Edge DevTools debugger.
  • Microsoft Edge extension scripts from appearing in Microsoft Edge Dev Tools.

It has now been noticed that Microsoft added this known issue to its support for KB4462933 article.

Developer Tools (F12) May Fail to Start in Microsoft Edge.”

A workaround to this issue was also suggested for anyone who uses Edge and these tools. It is suggested for these users that they delete the following registry entries with administrative privileges:

Using Administrator permissions, delete the following files and restart Developer Tools:

On to x64 machine: C: \ Windows \ SystemApps \ Microsoft. 
MicrosoftEdgeDevToolsClient_8wekyb3d8bbwe \
microsoft.system.package.metadata \ Autogen \ JSByteCodeCache_64

On to x86 machine: C: \ Windows \ SystemApps \ Microsoft. 
MicrosoftEdgeDevToolsClient_8wekyb3d8bbwe \
microsoft.system.package.metadata \ Autogen \ JSByteCodeCache_32

It is expected that this issue will be permanently fixed in the upcoming updates.

SQL Connection Problem

A second bug occurs in SQL connections which may occur in conjunction with a .NET framework update. This issue occurs after the installation of August Preview of Quality Rollup or .NET framework update of 11th September 2018. After installation, an exception will be there with Sql Connection instantiation. Microsoft described it as follows:

After you install the August Preview of Quality Rollup or September 11, 2018 .NET Framework update , instantiation of SqlConnection can throw an exception. For more information about this issue, see the following article in the Microsoft Knowledge Base:

4470809 SqlConnection instantiation exception on .NET 4.6 and later after August-September 2018 .NET Framework updates

Both these issues are expected to be fixed in the upcoming November Patch Tuesday update, scheduled to be released on the 13th of this month.

Until then, the above mentioned temporary solutions from Microsoft are recommended for users.
