Super Cleaner Plus
Analyze, clean, diagnose, and benchmark Windows drives safely.
Super Cleaner Plus 6.0 shows what is using space on Windows 10 and 11. Scan a whole drive or folder; scans do not modify files and create a local index of names and properties. Reports separate regenerable caches (SAFE), files you choose by size, type, date, or duplicates (CUSTOM), and system, program, or personal data requiring extra care (CRITICAL). Project-aware analysis identifies build caches and uses available activity signals to help protect active work. Before deletion, files are reviewed and rechecked; protected, changed, in-use, linked, and online-only files are skipped. The app also inventories installed programs and offers a backed-up uninstall workflow for eligible desktop apps. LIFE checks available drive health data and temperatures; DIAGNOSE reads NTFS, FAT, and exFAT structures, with CHKDSK repair only after confirmation; BENCH measures sequential and random speed, IOPS, and latency. Standalone 64-bit app; no separate .NET installation required. -

trimboot
TrimBoot maps & controls Windows startup items and right-click menus.
TrimBoot is a Windows desktop tool that maps autostart surfaces—Run keys, services, drivers, scheduled tasks, WMI, and related hooks—in one sortable view. It helps you see what launches at boot, spot new or changed entries, and review signing signals when paths point to files. Sensitive system items are flagged to reduce risky mistakes; where appropriate you can disable or remove entries using patterns designed for safer rollback. Monitoring highlights drift over time. Blacklist-style rules can match paths, hashes, or publishers for repeatable cleanup. A dedicated Explorer context-menu view reduces menu clutter without manual registry spelunking. Some changes need administrator rights; prefer disable over delete when unsure. TrimBoot improves visibility and control; it complements—but does not replace—antivirus and normal backups. -
