Clu's fingers flew on the touchscreen. He had seen photographs of common models of computers on Wikipedia on the ENCOM Phone he stole, but the device he was given to use was so much better: just a smooth glass surface to touch, and every connection was wireless. It reminded him of the interfaces he was used to in the Grid. That, he learned, was an ENCOM Pad.
Indeed, on this side of the screen, everything was a lot easier. He saved the file, compiled it and ran it.
"This will take care of the leak." he said.
He picked up the telephone, dialed a number and asked to talk with the sales department.
"Recall every copy of OS12." he said. "Yes, every copy. No, not just the unsold ones. Yes, ask our customers to ship them back and charge the expenses to us. Because next Monday we'll release OS12 Second Edition. It will be a huge event. Tell the press."
He hung up and said: "This will take care of the rest."

Clu walked out of his office, directed to Edward Dillinger's. "I am proud to announce that I solved our problems." he told Edward. "No more leaks, no more piracy, no more competition."
"What did you do, exactly?" Edward inquired.
"Heh." started Clu, with a grin. "I compiled and launched a worm that runs as root on any computer, disregarding the privileges of the current session. The first thing it does is to check for a copy of itself on any open connection, and if it does not find one, it creates it. The second thing it does is to run a cyclic redundance check on every compressed and uncompressed file in a computer. Every time it identifies a file as belonging to the leaked copy of OS12, it deletes it."
Edward Dillinger stared at Clu, his mouth agape. "You released a worm in the wild, from an ENCOM computer? Do you have any idea of what will happen to our PR?" he finally asked.
"Of course I didn't," Clu replied. "First, I was behind seven proxies residing in four continents. Second, I took control of a random computer at fCon. I compiled and launched the worm from there. If anything, I drove their PR into the ground."
"But if anyone connects to the Internet with OS12, his system will be erased!"
"With the version that's being recalled, yes." answered Clu. "On the other hand, the second edition will not work offline. Only if the computer is online and constantly connected to an ENCOM server, it will be authorized to run any program. And if our server detects a warezed version of OS12, it will send a command to delete every single file on the computer that's running it."
"But... but that's wrong!" exclaimed Edward, still stunned at what he was hearing.
"So, are you telling me that stealing our operating system was right?" Clu pushed.
"No, but..."
"Then what is your problem, exactly?" Clu interrupted Edward. "You can't have your cake and eat it too!"

Clu left Edward's office, directed to the digitization bay.
