Tendvane
Features

One app that does the IT work

Every tool is deterministic, explained in plain language, and reversible where it matters.

❤️ Health score

  • One screen, one number - press Check my PC for a score out of 100 and a plain-language list of what to fix and what's fine.
  • Rolls together the essentials - disk space, startup load, antivirus, firewall, UAC, pending restart, restore points and drive encryption.
  • Every item is actionable - a Show me button jumps to the tab that fixes it, with one-click fixes where it's safe.

🧩 Drivers

  • Full driver inventory with versions, dates and the official update source per device.
  • Online version check against the Microsoft Update Catalog - flags what's truly out of date.
  • Auto Update downloads and installs selected updates, batching them into a single restart, and resumes after a reboot.
  • Honest results - if Windows/OEM keeps a driver (common on laptop GPUs), it tells you and points to the vendor tool.
  • Back up & restore drivers (export to Documents) and an Auto-Update log.

📦 Install & Apps

  • One-click app installer via winget - popular apps grouped by category, each with a short description.
  • One app list - desktop and Microsoft Store apps appear together, Store ones marked with a tag, and you can uninstall several at once.
  • Search the whole winget catalog to find and install any app.
  • Installed-apps audit - sizes, install dates, last used, and "large & unused" recommendations, with Uninstall / Open folder.
  • Update all your apps at once - finds newer versions of everything installed and updates them in one click (via winget).

🌐 Network

  • Local network scan - every device on your network with vendor, hostname and open services.
  • Diagnostics - multi-stream download speed, latency and Wi-Fi signal/link rate.
  • Firewall - live connections per app, and one-click block/allow of any app's internet access (with confirmation). It never changes Windows Firewall on its own.
  • Wi-Fi passwords - see every saved Wi-Fi network on this PC and its password.
  • DNS benchmark - test popular public resolvers and find the fastest for your connection.
  • Fix internet (connectivity doctor) - checks your adapter, router, internet reach and name lookup in turn, then repairs the network in one click when something in that chain fails.
  • Who's on my Wi-Fi - flags any device that wasn't there the last time you scanned, so an unfamiliar phone or gadget stands out.
  • Wi-Fi channel - shows how crowded your channel is versus the neighbours and which 2.4 GHz channel is clearest, so you can switch your router if Wi-Fi feels slow.
  • Share Wi-Fi - pick a saved network and show a scannable QR code a guest points their phone at to join, with the name and password shown clearly too.

🩺 System

  • Alerts - recent Event Log errors and low-disk warnings, each with a one-click web search for a fix.
  • Security - antivirus, firewall, UAC, BitLocker and pending-restart status with recommendations.
  • Startup - programs that launch with Windows; disable or re-enable them (kept in the list either way).
  • Restore points, Performance (CPU, RAM, top memory users, S.M.A.R.T. disk health, temperatures), Battery health, Windows Update status with an in-app install, and Cleanup (temp, update cache, shader cache, recycle bin).
  • Security hardening - checks SMBv1, Remote Desktop, AutoPlay, the Guest account and UAC, and fixes each in one click.
  • Reliability score and a crash (BSOD) analyzer that names the likely cause of blue screens.
  • Storage analyzer (biggest folders & files) and a Changes log of everything Tendvane did, with one-click undo.
  • Unwanted-software triage - the "my PC is acting weird" check: hosts-file redirects, proxy hijacks, unsigned programs that auto-start or run as scheduled tasks from your personal folders, and your browser extensions.
  • Privacy & accounts - who can sign in (flags accounts with no password), BitLocker status with a recovery-key reminder, camera/mic/location app permissions, and your advertising-ID & diagnostic-data setting.
  • Ransomware shield - shows whether Windows Controlled Folder Access is protecting your Documents and Pictures, and turns it on in one click.
  • Breach check - tells you if a password has appeared in a known data breach, checked privately so your password never leaves the PC.
  • Reclaim space - finds the big, safe-to-clear items (Recycle Bin, hibernation file, Windows.old, Downloads) and frees them up.
  • Windows activation - clear "Activated / Not activated" status and your exact Windows edition.
  • Startup speed - your last boot time and the apps Windows blames for slowing it down.
  • Easy view - senior-friendly one-click text and mouse-pointer sizing, night light, high contrast and magnifier.
  • New PC setup - a four-step wizard for a new or refurbished PC: safety point, privacy basics, remove bloatware, install your apps.
  • Auto-maintenance (opt-in) - creates a restore point and runs a cleanup automatically when you open the health check.
  • Device battery - battery levels for your wireless mouse, keyboard, headphones and other Bluetooth devices, so a dying peripheral is never a surprise.
  • Printer helper - clear stuck print jobs, restart the print service, set your default printer and print a test page.
  • Pause & undo updates - pause Windows updates for 7-35 days and remove a recent update if it caused a problem.
  • Sleep & wake doctor - see and stop what wakes your PC on its own, and keep it awake during a download or backup.
  • Virus scan - run a Windows Defender quick or full scan and see any threats, right from the app.
  • What's running - the programs using the most memory now, with a one-click Close for a frozen app.
  • Browser cleanup - clear the cache of Chrome, Edge and Firefox (passwords and bookmarks kept).
  • Camera & mic watchdog - which apps used your camera and microphone, with anything active right now flagged.
  • New-program watch - flags anything installed since your last check, to catch software that installed itself.

🖼️ Photos

  • Duplicate-picture finder - matches by exact size then a SHA-256 content hash, so only byte-identical images are grouped.
  • Real thumbnails including iPhone HEIC, with a full-screen viewer.
  • Safe delete - keeps one of each group, sends the rest to the Recycle Bin, and shows reclaimable space.
  • All file types - the same byte-identical duplicate finder can scan every kind of file, not just pictures.

⚙️ Tweaks, Registry & Debloat

  • 126 tweaks from popular projects, deduplicated and grouped (Privacy, Performance & gaming, File Explorer, Taskbar & Start, Appearance, Windows Update, System) - all reversible, all localized.
  • Registry cleaner for broken references left by uninstalled programs, with a registry backup/restore.
  • Debloat (experimental) - remove pre-installed apps individually, disable telemetry scheduled tasks, enable optional Windows features, and clean Windows Installer leftovers (to the Recycle Bin).

🛠️ Repair

  • Symptom-based repair - pick the problem (no internet, printer, Windows Update stuck, hijacked browser, apps crashing, Store, wrong icons) and Tendvane runs the matching built-in Windows fix.
  • Browser-hijack reset clears forced extensions, homepage/search hijacks and a sneaky proxy; PC slow to start jumps to your startup programs.
  • End-of-life warning - shows your Windows version and warns when it has reached, or is near, the end of security updates.
  • Device quick-fix - one-click fixes for common hardware hiccups: sound stopped working, Bluetooth acting up, or a device (webcam, USB) not being detected.

💾 Backup & reporting

  • Back up your files - copy your Documents, Pictures and Desktop to a USB drive or folder you choose.
  • Full system report - a one-page summary of this PC's hardware and Windows, exported as HTML.
  • Settings profile to carry your tweaks to another PC, plus an optional weekly health report.
