George gets an error message in Microsoft Word that it's not responding as he's typing. After a while it wakes up and catches up. Leo says that the keyboard has a buffer and it will catch up as the buffer dumps out. But it won't catch everything. And George has Windows 10 with Office, so there's something going on in the background that's slowing George down. Windows could be background indexing. He should check the task manager. There may also be plugins from the browser that's slowing things down.
Jim's computer slow down to a crawl at the top of the hour. Leo says it could be a time based issue in Windows. Leo recommends rebooting it in Safe Mode and see if it still happens. If it doesn't, then something is running in the background that's causing it. He could also try another browser and see if that fixes it.
