On my system, one of the folders contains the log of the installation of an MSXML update. The following Microsoft article describes the folder and log file. I recall when I first noticed this folder that I found a reference on a Microsoft site (TechNet/MSDN/? -- I can't find right now) that the log file was created for troubleshooting purposes, in case the update was not successful. http://support.microsoft.com/kb/927978
From the article above:
"Security update package 927978 may create a log file. The package names the log file KB927978.log. The package saves the log file inside a folder. The folder has a system generated name. The folder is in the root of a system drive. The path resembles the following:
C:\system generated name\KB927978.log.
Note In this example, C is system drive.
Although it is optional, you can remove the log file and the folder."
Since that happened, I have noticed several other of these randomly-named folders have been created. A few of these seem to have been for Windows Live OneCare (the Microsoft anti-virus/anti-spyware/firewall program I use). These folders contain 2 small ".EXE" files. I do recall that, at one time, I had Microsoft Tech Support use a remote assistance tool to solve a problem I was having with OneCare. The contents of those folders may be from that support session.
I think if you look at the contents of each folder and find that they do appear to be just installation log files, then there should
be no harm in deleting them.
To be safe, you might might to create a new folder (at a location of your choice) and then move those 20 or so folders, along with their contents, into that new folder. Run the system for a week or two (or whatever) and if no problems appear, it should be safe to delete them. At least moving all those folders into a single folder will eliminate the clutter and you can then move one or more of them back to their original location if a problem develops.
