Note: Generally speaking, the C drive should be large rather than small. Unless you want to allocate it to other drives, please do not listen to the saying that the larger the C drive, the slower the computer will be.
Generally speaking, downloading the Win10 upgrade file occupies about 4G of hard disk. Taking into account the Recovery folder after the upgrade is completed, the normal situation is generally about 3G (depending on the software installation situation). Personally, during the beta version upgrade process , C drive has 13G of available space and can be upgraded normally, so the editor believes that 15G of available space can definitely meet the needs of upgrading Win10. It is recommended that friends upgrade to WIn10 and then use the Win10 image file to perform a new installation. You can skip entering the serial number and activate permanently. It can also ensure the normal available space of the C drive.
Mechanical hard drive or solid state drive is generally 1T, and the C drive is preferably 100G. If the solid-state drive is only 120G and you don’t install many applications or software, the C drive can be divided into about 50G. Decide on 100G if the space is large, otherwise you will have to repartition when installing other systems in the future.
Win10 is a newly released system. If there are loopholes and imperfections, it will be updated immediately. After the official release of the update and upgrade package, many Win10 users will receive it. The update prompts that there are available updates, but some users cannot update normally. Instead, a prompt appears: "There are available updates, but we temporarily need 0.00MB of space to complete the installation. Please delete some content you do not need immediately and we will try again. ". This kind of problem is expected to occur more easily in the future. According to the test results, 32.44% of domestic users will be unable to upgrade Win10 due to insufficient remaining space on the system disk. The problem mentioned here should also be the reason.
The solution is very simple, which is to expand the system disk capacity. Personally, I recommend that mechanical hard drives should be no less than 50G and solid-state drives with a capacity of less than 120G. Do not partition them. Simply use them as a system disk and install commonly used software! If the hard drive has reached a capacity of 50G and is being upgraded and installed, it is recommended to completely clean the C plate.
