Issues after upgrade Apache from 2.2.22 to 2.4.6 on Windows

Hi,

We have recently upgraded Apache to 2.4.6 from 2.2.22 on Win08 R2 platform.
Though we are able to work as before the upgrade. All the sites are accessible.
1.stopped the apache service 2.2
2. Downloaded the binaries from apachelounge.
3. copied the extracted bin and modules folders and replace the existing ones in the path <X>:/Program files>Apache Software Foundation >Apache2.2
4. made the adjustment to the httpd.conf as per the http://httpd.apache.org/docs/2.4/upgrading.html
5.uninstall the apache service 2.2
6 install the apache service 2.4
7. started the apache service.

Now we.re getting the error logs in apache:
