    Hi Rohan Rishi (Student) ,

    When Windows starts dragging its feet and apps like Outlook or Teams feel sluggish, the first thing I usually suggest is a quick reboot, it clears out temporary processes that might be hogging resources. If that doesn’t help, check Task Manager to see if something is eating up CPU or memory in the background (antivirus scans or updates can sometimes be the culprit). It’s also worth making sure Windows Updates are fully installed, since pending updates can slow things down. Another easy win is clearing cache and temporary files, especially if Outlook or Teams are hanging on startup. If performance issues persist, I’d recommend disabling unnecessary startup programs and checking disk space, running low can cause system - wide slowdowns. For Teams and Outlook specifically, signing out and back in or repairing the Office installation can sometimes resolve stubborn glitches. And if you’re on VPN or a slow network, that can also impact how responsive those apps feel. Bottom line: start with the basics (restart, updates, disk cleanup), then move into app - specific fixes if needed.
