Microsoft says it’s working hard to make sure the Windows 10 operating system takes up as little space as possible on your hard drive. Microsoft says that, thanks to super-efficient file compression, Windows 10 will leave you several GBs more space to use, depending on your device.
They promise that the compression will not affect the system, because they’ll factor in the amount of memory and the speed of the CPS when determining which files will be compressed. When you upgrade to Windows 10, it will automatically assess your device and compress Windows 10 files according to what works best with your system.
Compression will also ensure that apps from the Windows 10 store take up as little space as possible.
As devices get smaller and lighter, hard drive capacity is shrinking as well. It makes sense to use as little room as possible for the OS.
