when i open the C drive theres loads of folders appearing.they are labelled like dc9f174cc00f8c722c06b2b313 and inside them there is a file called msxml4-KB927978-enu.i looked at some of it.it says stuff like [11:02:36:156]: PROPERTY CHANGE: Adding ROOTDRIVE property. Its value is 'c:\'. MSI (s) (A4:18) [11:02:36:156]: PROPERTY CHANGE: Adding CostingComplete property. Its value is '0'.Modifying WindowsFolder.0E9F98FC_A692_A6DF_FF6B_D6B9ABF34537 property. Its current value is 'C:\WINDOWS\'. Its new value: 'c:\WINDOWS\'.more folders just keep appearing.why is this happening?
