i bought a windows 10 operating disc and installed it but the code with it will not work to activate it. it says this copy has exceeded its activation limit. this was a fault with windows 10 not techee. they gave me lots of customer support and went through everything till it was most likely to be a problem with windows activation. they told me to use the telephone activation on its free phone number which after about 15 minutes on the phone with windows support was fixed and my version of windows 10 is now activated and working fully. the help techee gave was very rapid and extremely helpful and will definately use techee again and would recomend them to others for there cheap price and excellent after sales customer service .
