WhatsApp Desktop
whatsapp.exe is safe. It's the legitimate WhatsApp Desktop application by Meta (Facebook) that allows you to send messages, make calls, and share media from your Windows PC.
whatsapp.exe is the executable file for WhatsApp Desktop, the official Windows application for the world's most popular messaging platform. Developed by Meta Platforms Inc. (formerly Facebook), it allows you to send and receive messages, make voice and video calls, share photos and files, and access all your WhatsApp conversations from your Windows computer.
WhatsApp Desktop is built on Electron framework (similar to Discord and Slack), which combines Chromium rendering engine with Node.js. This means it essentially runs a web version of WhatsApp in a standalone application container. The desktop app mirrors your mobile phone's WhatsApp account, requiring your phone to be connected to the internet for initial setup and periodic authentication.
Quick Fact: WhatsApp has over 2 billion active users worldwide, making it the most popular messaging app globally. The desktop version syncs seamlessly with your phone, allowing you to continue conversations across devices.

To verify authenticity: check it's located in Program Files\WindowsApps or AppData\Local\WhatsApp, shows Meta/WhatsApp as publisher in file properties, and was downloaded from whatsapp.com or Microsoft Store. Fake versions exist, so always download from official sources.
High CPU usage usually occurs during: active video calls (15-30% is normal), downloading media from chats, syncing large message history after being offline, or if the app version is outdated.

Uninstalling WhatsApp Desktop only removes it from your PC - all messages, contacts, and media remain on your phone. Your mobile app continues working normally. You can reinstall WhatsApp Desktop anytime and log back in. To uninstall: Settings → Apps → WhatsApp → Uninstall.
Yes, you can disable WhatsApp Desktop in multiple ways: Close it completely (right-click system tray icon → Quit), prevent auto-startup in WhatsApp Settings → uncheck "Open at startup", or disable it in Task Manager → Startup tab → WhatsApp → Disable.

This ensures you receive message notifications immediately without manually launching the app. To disable: Open WhatsApp → Settings (three dots menu) → uncheck "Open WhatsApp at computer startup", or use Task Manager → Startup tab → Disable WhatsApp.
Multiple whatsapp.exe processes (typically 2-5) are completely normal. WhatsApp Desktop uses Electron framework which creates separate processes for: main application, GPU rendering, network communication, and each chat window. This multi-process architecture improves stability - if one process crashes, others continue running. Total memory across all processes should be 150-500 MB during normal use.
No, WhatsApp Desktop requires your phone to be connected to the internet initially for setup and authentication. However, once linked, you can use WhatsApp Desktop while your phone is offline for a limited time (up to 14 days). The desktop app mirrors your phone's WhatsApp - your phone number remains the primary account. Without phone connection, you'll eventually be logged out and need to rescan the QR code.
