7 Developer Activation Kb780190 ((better)) — Windows

Article — "Windows 7 Developer Activation (KB780190)"

Known Issues & Limitations

• Some antivirus software mistakenly flagged early versions of this update as suspicious because it modifies SLAPI behavior.
• Not required for Windows 7 Home/Professional/Ultimate retail standard usage.
• Superseded by later cumulative updates if you install KB3125574 (Convenience Rollup for Windows 7 SP1).

Common Solutions

• Official methods:
  • Enter a valid retail, OEM, or volume license key using slmgr.vbs or Settings → System → Change product key.
  • Phone activation when online activation fails (still possible in many regions for valid keys).
  • Apply OEM-supplied recovery images that include activation.
• Supported update approach (historically recommended):
  • Install specific servicing updates and activation-related hotfixes provided by Microsoft for Windows 7 (examples cited in community threads include KB3138612, KB4474419, KB4490628) to ensure licensing components are up-to-date before activation.
• Unattended / imaging:
  • Use SetupComplete.cmd and scripts to programmatically apply product keys or OEM certificates during setup.
• Community tools:
  • Open-source scripts (e.g., "Windows7-OEM-Activator" on GitHub) that install OEM certificates and corresponding keys to restore OEM activation for supported manufacturers. These tools automate detection of manufacturer and certificate selection.

Option 1: Use an Existing Volume License Key (VLK)

If your employer has a Visual Studio Professional or Enterprise subscription, they can still download Windows 7 ISO and keys from the Visual Studio Subscriptions Portal (formerly MSDN Subscriptions). These keys never expire.

2. Broken Development Tools

Cracked activation often modifies:

• sppsvc (Software Protection Platform service)
• Hosts file (to redirect Microsoft activation servers)
• System volume information

These changes can cause:

• Visual Studio licensing checks to fail.
• SQL Server Developer Edition to flag invalid OS licensing.
• Hyper-V virtual machines to refuse to start.
• Windows SDK installers to abort.

Steps

1. Create the VM

   • Allocate 2-4 CPU cores, 4GB RAM, 64GB dynamic VHD.
   • Enable PAE/NX and VT-x/AMD-V.

2. Install Windows 7

   • When prompted for key, click "Skip" or "Next without key".
   • Uncheck "Automatically activate Windows".

3. Disable Automatic Updates (Temporarily)

   • Go to Control Panel > Windows Update > Change settings.
   • Select "Never check for updates".
     Reason: You will enable updates later manually after testing.

4. Install Integration Services

   • VirtualBox: Devices > Insert Guest Additions CD.
   • VMware: VM > Install VMware Tools.
   • This enables mouse integration, shared folders, and proper graphics.

5. Install Visual Studio 2015 (or your required version)

   • Use an offline installer from Visual Studio Subscriptions.

6. Extend the Grace Period

   • Open Command Prompt as Administrator.
   • Type slmgr -rearm and reboot.
   • Repeat up to 2 more times.
   • Each rearm resets 30-day timer (total 120 days).

7. Take a Clean Snapshot

   • In VirtualBox: Machine > Take Snapshot.
   • Name: "Clean unactivated baseline".
   • When the grace period runs out, revert to this snapshot.

This method is 100% legal because you are not bypassing activation—you are simply using the grace period Microsoft provides for evaluation. windows 7 developer activation kb780190
