Enough Space for Windows 10 Update 

Windows 10 always keep rolling out new updates. Looking back, there are many large build update, such as Windows 10 Anniversary Update, Windows 10 Creators update Windows 10 Fall Creators update and Windows 10 April 2018 update.

Then, many of you choose to install the latest Windows update. However, you may receive “Windows needs more space” error message when upgrading Windows 7/8.1 to Windows 10, or installing a new build of Windows 10. This means there is not enough space for Windows 10 update.

Besides, you may choose Windows 10 Update Assistant to download and start the installation of the latest version of Windows 10 but not enough disk space issue still appears.

So, how much space does Windows 10 take for the update? To upgrade to Windows 10, you’d better prepare 16GB free space in drive C for 32 bit OS and 20GB for 64 bit OS, which is recommended by Microsoft. Of course, more space is better.

Note: For Windows 10 May 2019 Update, both 32-bit and 64-bit versions require 32GB of available storage, which is a marked increase from previous versions of Windows 10.

In addition, since Microsoft gives users a chance to rollback Windows 10 to its previous build, there will be a folder called Windows.old created in drive C, which could take several GB of space. Therefore, upgrading to Windows 10 requires more space in C drive than a usual upgrade. 

Well then, how to fix Windows 10 creators update not enough disk space, not enough space for Windows 10 anniversary update or other updates?

6 Solutions to Not Enough Space for Windows 10 Update

If Windows 10 is running on HDD or SSD, you can try all these 6 methods. But if Windows is running on embedded Multimedia Card (eMMC for short), which is storage widely used on tablets and cheap laptops, the former 2 solutions might be useless for your case. 

Note: Some tablet users mistakenly think they are using SSD but actually using eMMC, which is largely because manufacturers or resellers introduce it vaguely. For example, Amazon describes HP Stream 13.3-Inch Laptop with Windows 10 installed uses 32GB SDD, but it actually employs 32GB Solid-State eMMC Storage. So, please carefully check the storage of your Windows 7, Windows 8.1, or Windows 10 device.
