WinRAR’s 40-Day “Trial” That Never Ends: The Genius of Eugene Roshal

This is Eugene Roshal, the software engineer behind WinRAR.

The creator of one of the most famous "free trials" in software history.

Back in 1995, Roshal launched WinRAR with a simple 40-day trial.

Pretty normal, right?

Except there was one unusual detail.

When the trial expired...

The software didn't stop working.

• No lockouts.
• No disabled features.
• No forced subscription.

Just a small message politely asking users to buy a license.

And millions of people clicked "Close."

Year after year.

As a result, WinRAR spread to computers all over the world.

• Students used it.
• Developers used it.
• Office workers used it.

Many people have seen the WinRAR trial reminder hundreds if not thousands of times.

What makes the story even more interesting is that this wasn't some clever viral growth hack.

It was simply the shareware model of the time.

The software trusted users to pay if they found it valuable.

And many businesses, organizations, and professional users did.

That revenue was enough to keep the project alive for decades.

Meanwhile, WinRAR became one of the most recognizable applications in computing history.

Even today, millions of people still use it to compress, extract, and manage files.

In an industry obsessed with subscriptions, paywalls, and aggressive upselling, WinRAR became famous for doing something surprisingly simple:

It asked.

And trusted users to decide.
