Having less storage space post-Windows 10 upgrade

You may not be aware of the fact that whichever operating system you upgraded to Windows 10 from still sits dormant on your PC for a while (assuming you didn’t install the OS from scratch). This can obviously lead to a drop in the available storage space on your system drive. 

To fix this, search for ‘cleanup’ in the Cortana/search box (next to the Start menu) and select the Disk Cleanup utility. When it eventually pops up – after scanning your drive – under the list of files you can tidy up, you should find one that says ‘Previous Windows Installation(s)’. Make sure this is ticked, and click OK – Windows 10 should then delete the older operating system’s leftover files, yielding a considerable 5-10GB boost in available space.

Note that if you have more than one drive on your PC, when you fire up Disk Cleanup, you’ll have to point Windows at your system drive where the previous OS was installed (usually C:).
