If you need the specific workflow of Actual Multiple Monitors, do not search for a repack. Go to the source.
Searching the common warez forums (which we will not link here) reveals a pattern. The "Actual Multiple Monitors 42 Repack" usually comes in a 15MB ZIP folder. The legitimate installer for version 4.2 is approximately 9MB. The extra 6MB? That is the "payload."
User reports from Reddit and TechPowerUp forums indicate that this specific repack often disables Windows Defender entirely, creates scheduled tasks that run PowerShell scripts at 2:00 AM, and injects DLLs into svchost.exe. One user reported that after installing the repack, their taskbar would flicker every 10 minutes—the flicker was the miner turning on and off to avoid detection.
Even if you avoid malware, using a cracked repack of Actual Multiple Monitors is software piracy. For a $30-$50 utility, the legal fines or civil suits (though rare for individuals) are not worth the risk.
