http://blogs.msdn.com/b/cjacks/archive/2008/08/29/what-is-the-trustedinstaller-entity-you-see-in-windows-vista.aspxA question came up in one of the comments asking me to please define TrustedInstaller. I've talked about it before a few times, but I've never gone through and dug through the implementation in a visible way. Time to change that - and we can do so withen-USTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)http://blogs.msdn.com/b/cjacks/archive/2008/08/29/what-is-the-trustedinstaller-entity-you-see-in-windows-vista.aspx#8976112Sat, 04 Oct 2008 06:17:46 GMT91d46819-8472-40ad-a661-2c78acb4018c:8976112Chris Jackson - MSFT<p>WRPMitigation is automatically applied to anything we detect as a setup, which is typically the time when most of these things occur. That's why you don't see it much. (Even misbehaving apps tend to try and drop old copies of things like shell32.dll at install time only.)</p> <p>No, we never give files permission to write there - we just create a new temp file and return this handle, so the app thinks it's writing there. If shimming it made writing there possible, and we auto-shimmed it, it'd be a pretty bad protection mechanism...</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=8976112" width="1" height="1">http://blogs.msdn.com/b/cjacks/archive/2008/08/29/what-is-the-trustedinstaller-entity-you-see-in-windows-vista.aspx#8975707Fri, 03 Oct 2008 19:54:59 GMT91d46819-8472-40ad-a661-2c78acb4018c:8975707ABC<p>only these Trusted installers will have complete rights to do anything on these WRP files and registries, right?.</p> <p>some applications are having WRP related issues, but still those applications will work on vista. How it is possible?....why this WRP is not breaking the functionality of the application, even the application is having the issue.</p> <p>sometimes if it is breaking the functionality, we are applying the WRPRegisterDLL, WRPMitigation &nbsp;kind of shims and it gets resolved. When we apply this shim, will it give permissions to modify those WRP files/registries? </p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=8975707" width="1" height="1">http://blogs.msdn.com/b/cjacks/archive/2008/08/29/what-is-the-trustedinstaller-entity-you-see-in-windows-vista.aspx#8922970Thu, 04 Sep 2008 01:11:16 GMT91d46819-8472-40ad-a661-2c78acb4018c:8922970Greg Lambert<p>These tips and tricks are really helpful. Understanding the Microsoft Component Based servicing stack and the Package Manager (ala Windows Installer) is essential to figuring out how applications install, uninstall, self-heal and repair under Vista and Windows Server 2008.</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=8922970" width="1" height="1">http://blogs.msdn.com/b/cjacks/archive/2008/08/29/what-is-the-trustedinstaller-entity-you-see-in-windows-vista.aspx#8907175Sat, 30 Aug 2008 01:44:51 GMT91d46819-8472-40ad-a661-2c78acb4018c:8907175send flowers &raquo; What is the TrustedInstaller Entity You See in Windows Vista?<p>PingBack from <a rel="nofollow" target="_new" href="http://hubsfunnywallpaper.cn/?p=3066">http://hubsfunnywallpaper.cn/?p=3066</a></p> <img src="http://blogs.msdn.com/aggbug.aspx?PostID=8907175" width="1" height="1">
