A couple of days back I  had my computer 
formatted. I reinstalled it with Vista SP1 32bit. Subsequent to 
installing other indispensable software  I tried to install SQL Server 
2005 .  However, it instantly displayed the following error message.
The SQL 
Server System Configuration Checker cannot be executed due to WMI 
configuration on the machine Error:2147749896 (0×80041008).
It was a bit frustrating for me as it was
 pretty late and I ardently wanted to install SQL Server 2008 right 
after I was done  with installing SQL Server 2005. I pinged my friend James Locazicoski with
 the above error message. James came to my rescue with a batch file. I 
immediately ran the batch file on my server;  it took a while and when 
it was done it closed itself on vista. I kept my fingers crossed and ran
 my SQL Server installer right after that.   There was no WMI error to 
wreck my nerve. I was able to successfully install SQL Server right 
after that.
Well, this bat file is certainly a life 
savior. While searching online I found this script at several places, 
which reflects its popularity and usability.  I need help from my 
readers regarding the following information
1) Where is the original source of this script?
2) What is this script actually doing?
Once I receive response to both the above questions, I will post the answers  on my blog with due credit to my readers.
