Windows 7 Stuck on Starting Windows

After a long time, I ran into a situation which really confused me. I am using Windows 7 Home Premium on my Dell laptop. Today when i started my laptop, it stuck on "Starting Windows" screen, tried following things

DID NOT WORK:
- Repair
- Safe Mode (also got stuck in safe mode)

then I tried (WORKED)

- Start windows :Using Last Known Good Configuration
It did start but the real problem was a unknown file "winlogon" (I know looks like system file), which was in my local TEMP folder. So following are steps to get rid of this file:

- Click Start > Run
- type "MSCONFIG" and click OK
- Select "StartUP" tab from top
- Look for "winlogon" file with unknown publisher and location --- C:\Users\\AppData\Local\temp
- Uncheck this file and delete from Temp folder
- Restart your system and you good to go.
- DONE!

Let me know, if this was helpful for you guys. I am sure it is, because it worked for me.
