The next big update of Windows 10 (in April) will mean that Microsoft will reserve 7GB of your device’s storage in order to accommodate its future ‘quality updates’ or new versions of the OS. Measures you can take to check that you will have enough reserved storage space or to avoid storage space problems include:
– Manually deleting unnecessary temporary files and (temporarily) moving important files e.g. photos and videos to external storage devices to make enough space for the update.
– Checking the size of the reserved storage on your system by clicking Start > Search for ‘Storage settings’ > then Click ‘Show more categories’ > Click ‘System & reserved’ > and look at the ‘Reserved storage’ size.
– Avoid buying devices with little storage capacity.
