I have the same log file but the folder has a different name guess that's due to each particular machine and OS version. I deleted it 2 days ago to test and nothing has happened yet. The log is an installation log and had not changed since it was installed in my case 11/17 .My thought is that if it is needed it will reappear next updates however you have auto updates set.
for Bob, John, and all you other experts out there,
The name of the folder is;
This is dated 11/22/06, the date I downloaded Microsoft's latest critical and other Windows Updates. I usually wait before updating in case any issues are reported.
Inside the folder is a log, msxml4-KB927978-enu.log, 284KB so its a very large log. Using Notepad I can see that it is an install log, and the first few lines are;

It's too large to copy the whole log here.
Microsoft's KB web site tells me at http://support.microsoft.com/?kbid=927978 that this addresses a vulnerability in Microsoft XML Core Services 4.0 that Could Allow Remote Code Execution.
There's is no listing for KB927978 in Add/Remove.
Do I need this log and this folder, or can I safely delete it?
