Windows 7 E is now obselete and a collectors item. You cant activate this with the keys that have been released so far. Re install to Ultimate or professional then you will have a flawless activation. Once Pro or ultimate is installed copy the vista hp cert to C:\ open cmd as admin. Issue the following commands slmgr -ilc c:\hp.xrm-ms slmgr -ipk (the key you have found searching the forums) to check activation after this enter slmgr -dlv you will be prompted with a realtime activation report. If any other help is needed post back.Also if you cant find a key pm me
Ok thanks - I am downloading normal version of windows Could anyon post a link to hp certificate? I saw only lenovo, dell and acer ;/
