We have many HP Stream devices and these have only 32 GB of storage. Windows 10 is a compact operating system and this is enough, particularly if you are mainly using them with cloud services. However there is a known bug in Windows 10 where sometimes Disk Clean-up (from disk properties or Settings > Storage) sometimes fails to remove temporary files. By using WinDirStat I found that I had over 4GB of un-deleted Windows updates. To do a brute force delete* of all temporary files open a command prompt as Administrator and,
rem delete temporary files del c:\temp\*.* del %temp%\*.* del C:\Windows\Prefetch\*.* rem Stop and restart the Windows update service Net stop wuauserv cd %systemroot% Ren SoftwareDistribution SoftwareDistribution.old Net start wuauserv del c:\softwaredistribution.old
* at your own risk, feel free to make a backup first.

I tried this but on the del c:\temp\*.* command it replied cannot find specified file. On the del C:\Windows\Prefetch\*.* part it replied access denied.

“c:\temp” that is OK. You don’t have to have one. To delete files in the prefetch directory you must have an Administrative Command prompt. If access is denied on individual files it is because they are locked and in use. You will want to find out what size they are to see if this an issue. – James
