#After the system is installed, the C drive will occupy approximately 15G to 20G. The key is to see how many applications your installed WIN10 integrates. Depending on the website you download from, the C drive space occupied by WIN10 is also different.
The reserved free space on the win10 system disk needs to be greater than 16GB (32-bit system) or 20GB (64-bit system). The available space of the system disk needs to be greater than 16GB for 32-bit systems; it needs to be greater than 20GB for 64-bit systems, which is the minimum requirement.
In actual use, this requirement is often exceeded. To ensure that all software is not installed on the system disk, the cache, registration files, drivers, temporary files, etc. generated by some software need to be written to the system disk. .
Although some software cache locations can be changed, you need to be familiar with computer operations. And some software needs to be installed on the system disk before it can be used.
There is also an app store in win10. Downloading, installation, caching, etc. are all in the system disk. The more you use it, the more system disk space it takes up.
Assume that the system disk space is 20G, and when the occupied space reaches 18 or 19G during use, the system will start and run slowly, run lags, and cannot enter the system.
Based on the above analysis, it is recommended that the minimum available space of the system disk be set to more than 30G. Users who are not familiar with computers can set it larger, because when these users install and use the software, they usually follow the default configuration of the software and directly install it. In this way, most software is installed directly on the system disk.
