Problem is solved now. Well the problem is more-so bypassed that solved. After all these failed attempts I created another administrator account (not built-in admin) to test if the repair worked and it did! The only problem I had left was trying to run any setup file on my E:\ drive (where I store My Documents, etc). I suppose I messed up some permissions or something on that drive and couldn't fix it even attempting some registry alterations with winiserver. ANYWAYS, I got around to copying everything from that drive, formatting it and moving everything back over. Finished setting up and personalizing everything and it seems to be running like old times.
Really really greatly appreciate all your time and patience guys. Each of you will earn reputation from me and I hope this thread may help someone in the future. Thanks again.
