You’re not “cracking Windows.” You’re deliberately lowering your defenses to run an unsigned, community-sourced binary from a site with zero accountability.
To run KMSauto, you must disable real-time protection, tamper protection, and sometimes SmartScreen. Once disabled, your system remains vulnerable to other threats until you manually re-enable everything (which most users forget to do).
Even the "clean" versions are flagged as dangerous because they mimic malicious behavior. However, third-party repacks (like those on Bagas31) have a history of including additional payloads:
KMS emulation is not perfect. After a Windows Update (especially cumulative updates), the activation may break, leaving you with a "Notification Mode" (nagging watermark and disabled personalization).
Security researchers have analyzed the Bagas31 repack of 155 Final. Beyond the activator, it often includes:
| Component | Behavior | |-----------|----------| | AutoKMS | Scheduled task to reactivate every week | | Defender Control v2.1 | Disables Windows Defender permanently | | Service installer | Runs even in Safe Mode | | Optional browser extension | Hijacks search results (Bing → custom ads) | | Registry cleaner (fake) | Actually just adds telemetry keys |
And in some variants: a hidden .NET-based downloader that fetches additional payloads — adware, at minimum; sometimes a remote access trojan (RAT).
VirusTotal scans of Bagas31’s
KMSauto.exe(155 Final) typically show 25–35 detections — but 5 of them are generic “hacktool” flags. The rest? Trojans like AgentTesla or RedLine stealer appear in ~15% of sampled variants.
For personal use on a non-critical machine (e.g., an old laptop for testing), you might take the risk. But for your primary work computer, gaming rig, or any device that holds personal photos, bank details, or work documents—do not use Bagas31 KMSauto.
Instead:
Save yourself the future headache of identity theft or a $500 ransom demand. Free software is never truly free.

Q1: Is Bagas31 KMSauto 155 Final New a virus? A: Not in the traditional sense of destroying data. However, it is classified as a "hack tool." Repacked versions from Bagas31 may contain additional malware. Proceed at your own risk.
Q2: Does it work for Windows 11? A: Yes, version 1.5.5 has been tested on Windows 11 21H2, 22H2, and 23H2. However, recent updates (2024–2025) have broken some KMS activators.

Q4: Do I need to run it again every 180 days? A: No. The "Final New" version installs a scheduled task that automatically renews the activation every 180 days without your intervention.
Q5: Is Bagas31 safe for other software? A: Generally, no. Repack sites like Bagas31, RuTracker, and PirateBay are the primary vectors for malware distribution. Use a virtual machine (VM) or an isolated PC if you must test such tools.
