How to use it:

1. Create a Windows 10 boot animation using pure CSS/CSS3. In this example, we use Font Awesome iconic font for the Windows logo.

<!-- Logo -->
<div class="logo">
  <i class="fab fa-windows" id="windows"></i>
</div>
<!-- Loader -->
<div class="loader">
  <div class="bg"></div>
  <div class="circle"></div>
  <div class="circle"></div>
  <div class="circle"></div>
  <div class="circle"></div>
  <div class="circle"></div>
</div>

.logo {
  position: absolute;
  top: 0%;
  left: 50%;
  transform: translate(-50%,0%);
  margin: auto;
}
.logo #windows {
  color: #0078d7;
  font-size: 120px;
}
.loader {
  position: absolute;
  bottom: 0%;
  left: 40%;
  transform: translate(-50%,-50%);
  width: 50px;
  height: 50px;
  margin: auto;
  transform: scale(0.8);
}
.loader .circle {
  position: absolute;
  width: 38px;
  height: 38px;
  opacity: 0;
  transform: rotate(225deg);
  animation-iteration-count: infinite;
  animation-name: rotate;
  animation-duration: 4.8s;
}
.loader .circle:after {
  content: '';
  position: absolute;
  width: 3px;
  height: 3px;
  border-radius: 50%;
  background: #fff;
  border: 1px white solid;
  box-shadow: 0 0 1px #0078d7;
}
.loader .circle:nth-child(2) {
  animation-delay: 240ms;
}
.loader .circle:nth-child(3) {
  animation-delay: 480ms;
}
.loader .circle:nth-child(4) {
  animation-delay: 720ms;
}
.loader .circle:nth-child(5) {
  animation-delay: 960ms;
}
.loader .bg {
  position: absolute;
  width: 70px;
  height: 70px;
  margin-left: -16px;
  margin-top: -16px;
  border-radius: 13px;
  background-color: transparent;
}
@keyframes rotate {
  0% {
    transform: rotate(225deg);
    opacity: 1;
    animation-timing-function: ease-out;
  }
  7% {
    transform: rotate(345deg);
    animation-timing-function: linear;
  }
  30% {
    transform: rotate(455deg);
    animation-timing-function: ease-in-out;
  }
  39% {
    transform: rotate(690deg);
    animation-timing-function: linear;
  }
  70% {
    transform: rotate(815deg);
    opacity: 1;
    animation-timing-function: ease-out;
  }
  75% {
    transform: rotate(945deg);
    animation-timing-function: ease-out;
  }
  76% {
    transform: rotate(945deg);
    opacity: 0;
  }
  100% {
    transform: rotate(945deg);
    opacity: 0;
  }
}

2. Create a Windows 7 boot animation using JavaScript and CSS.
