Free tools for your PC.
Two small, genuinely free Windows apps, made here. They run on your own computer with no account, no tracking and nothing to pay. Lock your files down, or find out exactly what is inside your PC and how it is doing.
Lockbox
Lockbox turns professional-grade encryption into two clicks. Pick a folder or some PDFs, set a password, and you get a locked file you can safely email or store - openable in 7-Zip or any PDF reader. For things you are keeping rather than sharing, the Strong Vault seals them with Argon2id and AES-256-GCM, built to defeat even dedicated password-cracking hardware. It all happens on your PC - the password is never stored or sent.
- AES-256 folder and PDF passwords (open in 7-Zip or any PDF reader)
- Argon2id "Strong Vault" - brute-force-resistant storage
- Built-in passphrase strength meter and generator
- Fully offline - the password never leaves the window
SpecCore
SpecCore answers two everyday questions: what is actually inside my PC, and why is it misbehaving? The My PC tab lists every major component - make, model and specs - each with a one-click link to the maker's official drivers. The Health check tab reads your Windows logs and turns cryptic error codes into plain English, telling you what happened and what to do about it. It only ever reads - it never changes a thing.
- Full spec sheet: CPU, GPU, RAM, motherboard, storage, BIOS, OS
- Checks Windows Update for newer drivers, with one-click links to each maker
- Plain-English health check of your Windows logs, with fixes
- Read-only - it never changes anything on your PC
Safe by design
Both tools run on your own computer - no account, no tracking, and your files are never uploaded anywhere. Lockbox works entirely offline. SpecCore goes online for one job only: asking Windows Update whether newer drivers exist for your hardware. Nothing else is sent, and never anything to us.
Bringing a PC in for repair?
Run SpecCore first and click Save report. Send the report with your enquiry and we arrive already knowing what is inside the machine and what Windows has been logging - it often saves a diagnostic visit.
