I installed Windows 7 Ultimate on a Lenovo laptop that originally had Windows 7 Home Premium. there was 289 updates two weeks ago, I made sure that they were all installed before shutting it down, but somehow the laptop magically downloaded and installed more while the computer was off for two weeks. I turn it on and get a "configuring Windows Updates" and then it automatically restarts, upon restart, it gets stuck on the Windows logos screen "starting Windows" for 20 minutes and now it has been stuck on the "Please wait..." screen for four hours! I hard shut it down, it get suck again same on Windows logo and same "please wait", hard shut down, choose safe mode, and the same thing happens yet again! I cannot get into the computer whatsoever and the machine was running PERFECTLY two weeks ago! It was flawless two weeks ago and now it won't get past the startup screen!
