Find what is wrong
Inspect system integrity, disk health, security, services, updates, drivers and network configuration. Fixable findings stay grouped by risk.
A closer look at the 158.
sunCleaner covers everyday cleanup and deeper maintenance without turning the interface into a wall of switches. Expand any group for the practical scope.
01Disk cleanup
69 tasks
Cleans disposable data while path guards block critical Windows roots and suspiciously shallow targets. Dangerous jobs such as event log clearing and PatchCache removal require explicit selection.

05Diagnostics and repair
28 checks
Scans first, reports clearly, then offers targeted fixes. Heavy and aggressive repairs remain opt-in, and machine-readable JSON reports support unattended maintenance.

Designed for deliberate changes.
System maintenance deserves visible controls. sunCleaner exposes selection, risk and reversibility before a deep tweak or cleanup reaches Windows.
Preview first. Change second.
Start with PowerShell WhatIf to see the real selected task count without modifying the system. When you are ready, restore points, registry backups and targeted guards add practical recovery paths.
Honest WhatIf
Uses the same selection logic as the live run.
Undo for tweaks
Backed-up registry values restore the previous state.
Protected paths
Blocks drive roots, Windows, System32, Users and shallow paths.
Restore points
Creates a checkpoint before supported system changes.
- SSafeSuitable for automatic repair.
- MModerateIncluded in standard FixAll mode.
- AAggressiveRequires IncludeHeavy.
- HHeavyMay be slow or require a reboot.
A clear path through maintenance.
Use the interactive console for one-off work or install the scheduled tasks for quiet recurring care with JSON reports.
See the scope
Run WhatIf and review the exact operations selected for this machine.
Keep control
Toggle categories and individual tasks. Risky operations stay explicit.
Clean, tune or scan
Follow progress in the three-color terminal interface and save reports when needed.
Undo with context
Restore backed-up tweaks or use the system restore point when a rollback is needed.
The useful extras are already inside.
Maintenance often reaches beyond temp folders. The toolkit includes focused utilities for common Windows jobs.
Network tools
Flush DNS, reset Winsock and the IP stack, inspect active adapters, set DNS servers or static IP details, and return an adapter to DHCP.
Startup control
Review approved startup entries and toggle them through the same checklist interface.
Scheduled care
Install a weekly unattended cleanup and a monthly read-only health scan. Both run as Windows scheduled tasks and write JSON reports.
