Windows Updates Folders (With Strange Names) in C drive

I don't know what are they and if it's ok to delete them. These are the folders:

These are the files that each of the folders contains:

alt text


edit: as per comments below, these are of course temp files, not rollback files as I incorrectly stated WRONG: These files are kept in case you want to roll back a windows update. Depending on how likely it is that you would ever want to do that and how old these files already are, you could probably bin them.

    Rollback information is stored in %SystemRoot%\$NtUninstallKB<id>$. These are just temp files. – user1686 Sep 4 '10 at 14:07

Those folders are where Windows Updates are unpacked before installation. Usually they are removed automatically, but if they aren't - reboot (to make sure) and delete them yourself.
