If you're thinking of buying a new computer, you may want to check which version of Windows 10 it comes with. There is a new kid on the block.
Windows 10S (Note the S) is a slimmed down go-faster version of Windows 10. It is claimed to be more secure.
By default 10S only runs software downloaded from the Microsoft Store. This may not be what you want or need : many applications are not available via the Microsoft store, and you are obliged to provide personal details. 10S also locks you into Edge, imposes other constraints, and may not be compatible with existing equipment:
'Many hardware accessories and peripherals (such as printers) that work with Windows 10 today will work with Windows 10 in S mode, but might have limited functionality.'
Early reports suggested that 10S would be permanently unable to install programs other than those made available via the Microsoft Store. However, the current version of the FAQ says it will be possible to switch 10S out of S mode one-way. Unfortunately it is not clear what effect rejecting 10S has on other features.
I thought Microsoft's FAQ on Windows 10S was unsatisfactory. It starts with a caveat: 'Details subject to periodic updating; check back here for the latest information.'. This is unhelpful if you are trying to make a fact based decision. More worrying, I do not think the FAQ unambiguously confirms that 10S can be made to behave like an ordinary unrestricted Windows 10 installation.
If about to buy a new computer with Windows 10S I suggest first reading Microsofts FAQ and then searching the web for up-to-date reviews. The product may not be for you!
