Selling tablets with windows 10 that don’t have enough disk space to upgrade is ridiculous. but that’s M$
Some ideas on increasing space
ou can ‘Compress’ all files and folders on it
currently deleting C:\Window\SoftwareDistribution to regain a couple gbs.
Move some of your user files to the sd card to clear up space.
Would you possibly have a windows.old folder
Turn hibernation OFF,
Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /RestoreHealth
Dism.exe /online /Cleanup-Image /StartComponentCleanup
This restored several gbs of disk space and allow the Windows 10 upgrade to 1709 to install.
Run chkdsk /f
ust plug in a usb flash drive with atleast 8gb capacity whenever the system encounters disk space problem,
Run Disk Cleanup (right click drive properties).
IRC around the time of 1511, the setup routine was patched to recognize an inserted SD card or USB drive as additional temporary storage during upgrade/reinstall operations. Slow for sure; but then, these machines aren’t speed demons anyway.
