Microsoft To Surface 3 Owners Don't Install Windows 10
Microsoft has issued a warning to Surface 3 owners not to install Windows 10 Technical preview on their device.
In the Microsoft community website, when asked about installing Windows 10 Technical Preview on Surface 3 tablet, community moderator Barb Bowman responded not to install it, as there are no drivers for Intel x5 /x7 Atom processors.
Please do NOT try to install Windows 10 on the new Surface 3. There are no drivers for the Intel x5/x7 Atom processors. There are no drivers in the Preview Build because Intel has not yet provided drivers. There is no block/check for these processors in current builds. Timing of availability for drivers is unknown as Intel is still working on the needed drivers for the new chipset and processors.
Couple of months ago, Microsoft launched Surface 3 as a lighter and smaller version Surface 3 Pro. The Surface 3 runs on Intel Atom processor instead of the core i-processor powering Surface 3 Pro. We expect that once Windows 10 is out of development, Intel should have the drivers ready and Windows 10 can be downloaded and installed on the Surface 3. In the meantime Surface 3 users has to wait for the official Windows 10 release that is expected to happen towards the end of July, if previous reports are to be believed.
