What it is for
Taking over a computer you have never seen. Run a full system scan and get a ranked list of what needs attention before you change anything.
Closing a ticket with proof. Export the readable report with the evidence behind every finding, so a repair is shown as verified rather than assumed.
Your theme. Traceable findings.
Textured surfaces, the Killer Tools wordmark, and 13 app themes. The smoked-glass console, readable reports, confirmations, and Open, Save, and Folder dialogs follow the active app theme.
Part of the Killer Tools family
Inside the workbench
Twelve sections, one habit
Diagnostics, Repair, Updates, Devices, Network, Apps, Maintenance, Onboarding, Security, BitLocker, Privacy and Storage. Every tool reads before it offers anything, and a full system scan ranks what needs attention.
Fix only what is proven
A repair is offered only when fresh evidence matches the exact problem. It needs your confirmation, rechecks everything right before it runs, and reads the result back before it says Verified.
No black boxes
Findings link to the event, log line or setting behind them. Incomplete evidence is never reported as healthy, and history stays history. Export the report straight into a ticket.
Encryption without guesswork
Inspect protectors, back up recovery passwords to a file, Active Directory or Entra ID, encrypt Windows and data drives, turn on auto-unlock and prepare a TPM without ever clearing it.
Make a laptop yours
Review and change privacy settings, app permissions and cloud search, then declutter Windows. Settings owned by policy or device management are left alone.
Check before retrying
Journaled repairs record a pending request before dispatch. If a request is interrupted, recovery checks what happened without automatically repeating the change.
No AI required
Diagnostics and report analysis run locally without an AI service or KillerBench account. Actions you select, such as downloads or recovery-key backup to Entra ID, can contact their destination. The same Engine powers the desktop app and command line.
