PC Health Check FreeBack

A free app that checks your PC's condition. It automatically checks 5 items — low-memory prevention, unused software, desktop cleanup, USB AutoPlay, and ad blocking — and lets you fix anything worth fixing on the spot.

01What Is This?

Computer Check-Upis the routine we've followed to fix the glitches and usability issues on the PCs we use in-house, ourselves, day to day. This app turns that same routine into free software anyone can use. It shares its roots with our paid app, "Pc-AI-Doctor," but here we picked the five items from that checklist that are safe for anyone to use, and left out the AI conversation feature, for a simple, free tool.

Low-memory preventionSets the page file (virtual memory) to a fixed, sufficient size.
Unused software checkShows the count and opens "Programs and Features" (nothing is removed automatically).
Desktop cleanupMoves only the loose files on the desktop into a stash folder (folders are left alone).
USB AutoPlay repairRepairs it when a USB drive stops responding when plugged in.
Browser ad blockingBlocks domains commonly used for ad delivery. Can be toggled ON/OFF.

02DownloadFree / Ver.5

Installer (with help and description files)

Download PCHealthCheck_Setup.zip

The zip contains the setup program plus help and description files in both Japanese and English. Extract it and run the setup — you can choose whether to add a shortcut to the desktop, Start menu, and/or taskbar (the app and installer automatically match your Windows language setting).
When opening the file for the first time: if Windows shows "Windows protected your PC," click "More info" then "Run anyway" (this appears because the file is not digitally signed). Also, each time you click a "Fix" button, Windows shows a confirmation screen (User Account Control) once — this is Windows itself confirming a change to your PC's settings.

03Requirements and terms of use

PC Health Check began as our own in-house "Computer Check-Up" practice, rebuilt here for anyone to use.
