Can I delete $NTUninstall program,s?

In my system there is a huge collection of $NTUninstall files. I checked the size of those files which lies around 1GB. It looks this files are accumulating in my system from the date of purchase. I am having a laptop here. I am using Windows XP on the same. Now I am getting low disc space error message. I want some help here to empty the space. So just want to ask whether it is safe to delete this files. I do not want to generate any other error. My system is working fine.

This are files which are associated with the uninstallation part of an application. It can be associated with updates or software's. It is necessary that you must remove some of them only. But it will be completed to find which one must be avoided. You can try running Disk Cleanup. Select everything from that. And run is on regular basis. I am sure that will be a bit safer enough to fix the problem you are facing.
