Apache installation and configuration

Download the Apache 2.0 httpd binary from Apache.org (search for windows, other files)
Normal install (for example in C:\Program Files\Subversion)

Copy these 4 files from C:\Program Files\Subversion\bin
  mod_authz_svn.so
  mod_dav_svn.so
  intl3_svn.dll
  libdb44.dll
To C:\Program Files\Apache Group\Apache2\modules

Add these two lines to httpd.conf
  LoadModule dav_module modules/mod_dav.so
  LoadModule dav_svn_module modules/mod_dav_svn.so

And these at the bottom of the httpd.conf file,
assuming you run the repository on the root directory.
And the SVN repository is stored at d:/temp/svn

<Location />
DAV svn
SVNPath d:/temp/svn
</Location>

Restart Apache server, it should be running
