It is not a setting in applicationHost.config. You are supposed to set it via adsutils.

However, the recommended approach is to get rid of it,

In the article

they told us to do 

cscript adsutil.vbs set w3svc/etag_changenumber 0

However in IIS 7 application host, w3svc  does not exist anymore.

Do you know what ID we can use?

Thanks and regards,

Hi Eric

The MD_ETAG_CHANGENUMBER property is used by IIS 6.0. When you set the MD_ETAG_CHANGENUMBER metabase property in Microsoft Internet Information Services version 6.0 to improve Web browser caching performance, performance does not improve. 

But you install the hotfix to honor the MD_ETAG_CHANGENUMBER property in Internet Information Services version 6.0.
