And once AMD got their act together with drivers I have not had a single stability issue since the upgrade. Daz555
This style of report confirms that Win10 (the complete offer, not just MS's product) wasn't ready for prime time but is probably getting nearer to that state, and hence confirms my view not to update any systems until April 2016 at the earliest.
Also by that time I would hope that many printer vendors will have developed Win10 compatible drivers for widely used printers, so I can advise clients whether they will also need to purchase a new printer or not...
