This error is the most frequent complaint. Here is why it happens:
| Error Cause | Solution | |-------------|-----------| | Typo or extra spaces | Copy-paste directly from your email. Ensure no leading/trailing spaces. | | Wrong version | If you have a key for “StartIsBack v1.x” on Windows 10 v2004+, it will fail. | | Hardware change | A motherboard or CPU swap may deactivate the license. Contact support with your old key to request a reset. | | Server outage | Rare, but wait 30 minutes and retry. | | Windows insider build | Pre-release Windows builds often break activation. Wait for a software update. |

When you bought StartIsBack, you received a key. It wasn't a massive corporate license server like Adobe or Microsoft uses. It was a small, personal string. This created a unique dynamic.
The "interesting" part of the story isn't the key itself, but what people did to avoid buying it. Because StartIsBack was a one-man operation, it became a target for a specific type of "crusade" in the internet’s darker corners. A StartIsBack key will NOT work for StartAllBack
No. Using any StartIsBack key that you did not directly purchase from the developer or an authorized reseller violates the End User License Agreement (EULA). This includes:
While Microsoft does not police StartIsBack usage, the developer actively tracks activation abuse. Keys that appear on public lists are added to a denial list, often within hours. When that happens, the software reverts to trial mode automatically.
