Hardware related and therefore going off topic + it is best to only deal with one problem at a time in any one thread.
This is also going off topic and a completely different scenario, you may find that many of your Windows 7 programs are not compatible with Windows 10 + there may also be product keys that cannot be reused on any computer other than that which they were originally purchased for.
To summarise, your request for help was titled "Win 7 profile refuses to logon" we tried helping you with that but along the way the legitimacy of the Microsoft software has been cast into doubt, due to the poor condition of the computer you were concerned about losing your data and so asked for help with backing up the data, we have helped you with that, we are now at a point where no more assistance can be offered with this computer until we have checked that the OS is legit, we are all bound by the GTG Terms of Use and by continuing to help we would be breaching the rules that have been put in place to protect us all, please run the WV Check and post the log so that one of us can check it, you have spent many hours backing up without the computer failing so it is highly unlikely that it will do so by you running such a light weight task as this;
As said no problem with how long things take as long as things are done right.
