Hi, hope someone might be able to help out. In a rash moment, i agreed to have look at a friends pc (AMD Duron 1300mhz, 128mb ram, Pcchips m/b with onboard vga hogging 8mb of the memory, running Win XP home!!). I took the pc home to deal with, after initial spyware checks found over 2500 infections! (6 months of 2 teenage offspring using a broadband connection with no firewall or a/v!). Unfortunatly, no Windows disk to re-install with, nothing so easy! Got the machine runnin a bit better - program removal, spyware and a/v scans and some simple registry cleaning using jv power tools. My problem lies with a selection of programs that don't uninstall due to missing files, and i think this stems from the programs being originally installed from user accounts that don't exist anymore. I could be totally wrong here, quite a few of the programs that won't uninstall are asking for missing install logs or dat files, leading me to my above mentioned prognosis, however a few of the errors quote '16 bit windows subsystem' 'not suitable for running MS-DOS and Windows applications' leaving me wondering if this XP installation was a crude upgrade! I decided cleaning up some of these unused accounts might help system performance but your observations or suggestions would be appreciated. From the XP log on screen, there are 2 user accounts (both admistrator), but in the Documents and Settings folder of the system drive, there are 10 accounts (Administrator, All Users, Default User and 7x user named accounts). I'm presuming that the problem ones are the 5 unused user named accounts. Can anyone point me to the right way to get rid of these accounts and their registry entries, as they are not removable from the control panel/user accounts or system properties/advanced/user profiles tab, and just deleting the folders fails also. Sorry if i'm missing something obvious, but I'm not that upto date with XP! thanks, phazz
