So far I must say I'm very impressed with the way Win 7 has handled my hardware drivers. My system consist of old 8 year+ hardware. Every thing has installed faultless. Two nights ago I tried installing my MS Elite bluetooth KB. Everything installed fine, entered bluetooth link code via k/board but keyboard does'nt work after that. Also does'nt show in K'board software but it is listed in the BlueTooth device manager. Seems Microsoft product has compatiblity issues with there own hardware.
