Another thing to keep in mind is that browser compatibility is becoming a challenge too-many modern sites, including WhatsApp Web, may stop working properly as browser support for Windows 7 dwindles. If you start encountering issues with loading WhatsApp Web, trying a portable version of a browser like Firefox ESR (Extended Support Release) can help delay compatibility problems. Long-term, though, staying on Windows 7 for messaging will only get tougher, so having a transition plan in mind is smart.
