Windows Update is a specification that keeps the updated files on the local drive.

The copy of the update program squeezes the local drive of the PC in proportion to the number of times Windows Update is executed.

"Disk Cleanup" has the function of deleting or compressing the backup files of updates stored in the local drive.

Since it is a Windows system tool, you can use it with confidence.

You can expect the following when executed.

How Windows Update works

Since Windows Update determines the files to download by comparing the update program on the cloud server with the "copy of the update program" on the local drive, the more files that are compared, the longer it takes.

It also scans for other devices (such as Wi-Fi adapters) and driver versions.

Taking my PC as an example, Windows Update needs time to find a copy of the 6.9GB update.

Although,

Since the local drive is SSD, it's a time I don't mind. (^. ^)
