It looks like after having offered a workaround for issues that arose in about 12 percent of PCs running the Windows 10 Technical Preview build 9879, Microsoft went ahead and released a hotfix to patch up the situation. You can download the update from Microsoft directly if you're a Windows Insider participating in the Windows 10 Technical Preview.
According to Gabe Aul of Microsoft:
New hotfix posted for #WindowsInsiders on WU that fixes the underlying issue for http://answers.microsoft.com/static/html/error.html?aspxerrorpath=/en-us/windows/forum/windows_tp-windows_update/how-to-install-windows-10-technical-preview-update/7454922c-cbcf-49f7-ba52-a2d85a5b4bdc .
