NSSM vs SterJo Startup Patrol

NSSM is a Windows service helper that runs an application as a service, watches its process, and responds when it exits. A graphical interface installs or removes services, while command-line options support scripted configuration. On exit, NSSM can restart the application, ignore the event, terminate itself, or exit uncleanly so Windows recovery actions can run. It records its own progress in the Windows system Event Log and can redirect the monitored program’s input and output. Output files can rotate at a configurable size, including while the program continues running. Administrators can set process priority and CPU affinity, and start, stop, or query services. NSSM provides 32-bit and 64-bit binaries and says it should work on Windows 2000 or later. It is public domain, with source usable for any purpose. The site lists version 2.24 from 2014-08-31 as latest, plus a 2017 prerelease. Administrator access is required; documented bugs affect newer startup, XP, and large log rotation.

SterJo Startup Patrol is a free Windows utility that monitors startup registry locations and startup folders in real time. It alerts when a program attempts to add a startup entry, showing the program name, full path, and modified location. You can allow, disable, or delete the change from the alert. Its main window lists active entries for manual disabling, and previous decisions or permissions can be adjusted later. Additional tools include digital-signature checks, a right-click Google search for unknown entries, and a portable edition for USB use. The portable version runs without installation and is described as not modifying system files. Version 1.6 is listed at 2.2 MB and adds an alert sound for new entries. Supported Windows versions are 11, 10, 8, 7, Vista, and XP in 32- and 64-bit editions. Scheduled Tasks are outside its core monitoring. The maker says Startup Patrol is not an antivirus, though it can flag potentially suspicious startup changes.
