I'm trying to clean up space on my c drive. Running Windows XP SP3. The folder C:\WINDOWS\Installer is 3.9 gb. did a search hear and saw some mention of MsiZap. This utility is not on my system now and a search of the MS download center comes up empty. Would this help me here? If so, where can I find the program? How should I run it and with what params?
If this will not help me are there any other options for either deleting or moving these files without hurting my system?
