NtUninstall folders in Windows 2003 Server

NTUninstall folders 2NTUninstall foldersNTUninstall folders 3I have Windows server 2003 and discovered that there are over 3GB of data in these "$NtUninstallxxxx$" folders mostly dated from 2006 (when this server was set up first time) thru 2015.  When I opened some of these folders, they all have .DLL files.
Can I purge these files?

here is the recommended process to Remove those folders:

Links to these $NtUninstall folders are placed in the Registry entries for each update, so that Windows knows where to find the uninstall files for each update. Simply deleting the folders would cause these Registry entries to become invalid. In the majority of cases, Windows updates are never uninstalled. If an update does need to be removed, the necessity for this will usually become apparent very quickly. So it is perfectly safe to remove the uninstall folders for updates that are more than a couple of weeks old. But how to remove them cleanly?


Manual removal
Perform the following steps:
Open Windows Explorer, click Tools, Folder Options and select the View tab.
Ensure that Show hidden files and folders is selected.
Open C:\Windows.
Start the Registry Editor (click Start, Run and enter regedit.)
For each of the blue $NtUninstall folders that you wish to remove:
Make a note of the name or KB number that follows the word Uninstall.
Delete the folder.
Delete the file named [name/KB number].log and delete it.
In the Registry Editor, expand SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
Delete the subkey [name/KB number].
Expand SOFTWARE\Microsoft\Windows\CurrentVersion\App Management\ARPCache
Delete the subkey [name/KB number].
