Hello Mario,
Try MVP MowGreen's reply to an earlier post last month involving the error:
0x800f0900 CBS_E_XML_PARSER_FAILURE
unexpected internal XML parser error.
See if running this tool resolves the error:
AU Check (v78a
<http://www.codeplex.com/aureset/Release/ProjectReleases.aspx?ReleaseId=17263>
Download and *save* it. After the download completes close all open
programs and browsers.
*** Temporarily disable the installed antivirus/security
suite/anti-malware/3rd party softwares. This includes all services nd
processes associated with them. Either consult the User Guide or the
manufacturer's web site to learn how this is accomplished.
You can use the following steps to Clean Boot Vista if the above task is
too complicated: How to troubleshoot a problem by performing a clean
boot in Windows Vista

*Enable* the native Vista firewall as the system must be connected to
the net when the tool runs so that it can downloaded needed updating
software components. ***
Now run au_check_v78a_codeplex.exe by *right* clicking it and choosing
'Run as administrator'. Allow it time to complete it's operation.
Reboot afterwards.
See if the system can update now.
