I have windows Xp on my machine and wondered if there is any way to LOCK the desktop icons so that they cannot be moved. I tried to do it via the registry and change it so that on restart the icons are all placed back the way i want them but that DIDNT work either. I know there is software that you can download to do this kind of thing but wondered if there is a simple way through windows or tweak manager???found a windows tweak that fixed my problem.What is it? The tweaks I've seen don't seem to last more than a couple of reboots and seem to introduce unwanted EFFECTS such as context menu garbling.its tweak 188 on this site
http://www.kellys-korner-xp.com/xp_tweaks.htm it has .dll file that goes into the system32 folder and a script that you run after the dll file is in the right place. once youve done this you can right click on the desktop once it is ARRANGED how you want it and save the settings. anytime you want to revert back to these settings from then on you simply right click on the desktop and choose restore desktop icon LAYOUT. its very effective and hasnt caused me any problems so far.
