Solution for the lack of c disk space when upgrading Win10 system

Win10 size is about 2, 3G, decompression Win10 may need 6, 7 G. Now there are dozens of Gs in the disk space. It is reasonable to say that installing Win10 is enough. However, Win10 is upgraded on the basis of Win7 and Win8. Win7 and Win8 will occupy C disk space, so there will be insufficient space for C disk to install Win10. Is there any skill to upgrade Win10 when the C drive space is insufficient?

Solution:

Microsoft added a clever link during the installation and upgrade process of Windows10 www.xitonghe.com/win10/. When the upgrade program detects that the C drive does not have enough free space. Not only will the user be prompted to manually clean up the space, but also provide two options:

1. Insert a USB flash drive to get extra space, but it must be 16GB or more;

2 select a link to another partition or external hard drive to get extra space (9GB above);

so if you encounter insufficient disk space C cases, you can select the above two options to expand the C drive This is the trick to upgrade Win10 when the C drive space is insufficient.
