   <scheme name="xpress" doStaticCompression="false" doDynamicCompression="true" dll="C:\Windows\system32\inetsrv\suscomp.dll" staticCompressionLevel="10" dynamicCompressionLevel="0" />

   
   
5. Remove / Disable the XPress compression schema from the configuration using the command below:
   

   %windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/httpCompression /-[name='xpress']
