Windows Update has planted a folder on my C drive

for Bob, John, and all you other experts out there, Happy

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;

=== Verbose logging started: 22/11/2006 10:15:45 Build type: SHIP UNICODE 3.01.4000.2435 Calling process: C:\WINDOWS\system32\msiexec.exe ===
MSI (c) (44:B8) [10:15:45:859]: Resetting cached policy values
MSI (c) (44:B8) [10:15:45:859]: Machine policy value 'Debug' is 0
MSI (c) (44:B8) [10:15:45:859]: ******* RunEngine:
******* Product: c:\573d0d998e64e31757189a4ec32ecc74\msxml.msi
******* Action:
******* CommandLine: **********
MSI (c) (44:B8) [10:15:45:859]: Client-side and UI is none or basic: Running entire install on the server.

It's too large to copy the whole log here.

Microsoft's KB web site tells me at 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?

Many thanks.

Hi Mark,
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.

The installer just didn't do a very good job of cleaning up after itself. There shouldn't be any problem with deleting that file and directory.

Thanks for that Shirley. Very interesting, especially that Donna found hers on another partition/drive.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
