Autoruns vs Defragger

Autoruns shows programs and drivers configured to run during Windows boot, login, or when certain built-in Windows applications start. It reports startup items from locations such as the Startup folder, Registry keys, Explorer extensions, services, scheduled tasks, and Winlogon entries. Users can hide signed Microsoft entries to focus on third-party items, inspect startup images configured for other accounts, and disable an entry or delete its configuration. Scan options include signature verification and VirusTotal hash checks; submitting files not previously scanned requires the upload option, and VirusTotal features require accepting its terms. The download includes Autorunsc, a command-line version that can output CSV or tab-delimited data, verify signatures, and scan an offline Windows system. The Autoruns and Autorunsc download is listed as 3 MB, and Microsoft offers a Sysinternals Live option. Autoruns costs nothing, with no limit on installation or use on devices owned or supported by the user, but no redistribution license. Microsoft says Sysinternals tools are provided as is without official support and points users to a community forum.

Defragger is a graphical Linux tool for examining and defragmenting filesystems, with a map showing file, free-space, and metadata allocation. Its analysis identifies fragmentation and displays filesystem blocks in an adaptive map. The project supports online defragmentation of ext4 and offline defragmentation and compaction of FAT16 and FAT32. FAT12 and exFAT can be analyzed, but not modified. A command-line interface can list, analyze, defragment, and compact volumes. The interface and command-line program run without elevated privileges; operations that need them use a PolicyKit-authorized helper over D-Bus. The stated environment is Linux with Qt 6 and KDE Kirigami; privileged mode also requires systemd, PolicyKit, and an active graphical PolicyKit agent. For ext4, Defragger uses Linux filesystem ioctls directly rather than calling e4defrag or filefrag. The project labels the software alpha, recommends backing up important data, and says ext4 has received the most testing. FAT write support is newer, so it recommends beginning with disposable or fully backed-up volumes. The software is dual-licensed under MIT or Apache License 2.0.
