Can not automaticly block TecentQQ access to camera, even if I set avp block all program access camera.

<p>It is highly likely that patch K for 2018 product also share the same problem.</p>

<p><strong>Reproduction steps:</strong></p>
<p><span></span>Check the option ' block access to webcam for all apps'</p>
<p>start windows UWP app ' camera', try take a picture</p>
<p>start tencent QQ, show camera preview in its sitting</p>
<p>in the Green notification box, choose block this app access to camera</p>
<p></p>
<p><strong>Actual result:</strong></p>
<p><span></span>UWP camera app report that it do not have access to camera</p>
<p>but QQ success show camera image</p>
<p>after manual block access to camera, QQ can not show camera preview anymore</p>
<p></p>
<p><strong>Expected Result:</strong></p>

<p>Similar problem to support case INC000008572247 and possible it is Bug 2484338:[SUPPORT] Webcam protection doesn't work on integrated webcam.</p><p>Is that issue also actual for 2020?</p>
<p>Looks like it is not patch issue, because it also present for 2018</p> -

<p>No, can not reproduce in 2020</p>
<p>but in previews patch for 2018, there is no problem. Also no problem in 2019 patch A.</p>
<p>One day, I remember, after update of patch B for 2019, webcam protection became useless for all program, not just QQ. </p>
<p>After patchC fix the issue( this was mentioned in release note of patchC), only blocking QQ use camera become a problem.</p>
<p>Webcam protection useless for QQ is not a new bug, I reprot such problem to support approximately a year ago.</p>
