Registry Modifications

• The following Registry Keys were created:
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{5460C4DF-B266-909E-CB58-E32B79832EB2}
• HKEY_CURRENT_USER\Software\((Mutex))

• The newly created Registry Values are:
• [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{5460C4DF-B266-909E-CB58-E32B79832EB2}]
• StubPath = "%ProgramFiles%\InstallDir\setup.exe restart"

so that setup.exe runs every time Windows starts

• [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
• HKLM = "%ProgramFiles%\InstallDir\setup.exe"

so that setup.exe runs every time Windows starts

• [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run]
• HKCU = "%ProgramFiles%\InstallDir\setup.exe"

so that setup.exe runs every time Windows starts

• [HKEY_CURRENT_USER\Software\((Mutex))]
• ServerStarted = "6/19/2012 15:53:05 PM"
• InstalledServer = "%ProgramFiles%\InstallDir\setup.exe"
