preface

Recently, it is often found that Windows10 system is stuck, notebook fan sound is particularly loud, the CPU occupation of the local system has been maintained at about 100%, the slow response of the program seriously affects efficiency. The situation may vary depending on the Version of Windows, but the task manager shows that high CPU processes are concentrated in Windows Update, which is the source of the high CPU problem. However, looking back on the automatic update experience of Windows XP/Vista/7/10, Microsoft has been moving forward. At least my X230 has been upgraded to 1803 with the first version of Windows10 Pro after replacing it with SSD and large memory. No more reinstalling your computer every once in a while because of too much junk data or slow system response. What’s your story?
