Steps to reproduce

Before Windows 10, in WIndows 8.x and 7 the only way to increase default maximum size of HTML5 application cache allowed for a domain was to use the group policy “Set application cache storage limits for individual domains”. It worked fine for IE 10,11 and IE with Metro interface (predecessor of Edge). After calling MS Support (see case
117102516556113) it was discovered that Edge and IE need to have extra registry keys to be set (which are missing in Windows 10). There is no UI to for this (previously browser was asking user to allow increase if site requested it), no alternative GPO, no documentation. The registry keys are as follows:

For Edge:

  • HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Storage\microsoft.microsoftedge_8wekyb3d8bbwe\MicrosoftEdge\BrowserStorage\Appcache\MaxTrustedDomainLimitInMB
  • HKLM\Software\Microsoft\MicrosoftEdge\BrowserStorage\AppCache\MaxTrustedDomainLimitInMB

For Internet Explorer 11:

  • HKLM\Software\Wow6432Node\Microsoft\Internet Explorer\BrowserStorage\AppCache\MaxTrustedDomainLimitInMB
  • HKCU\Software\Microsoft\Internet Explorer\BrowserStorage\AppCache\MaxTrustedDomainLimitInMB

This is really a big flaw for business environment using trusted LOB web applications.
