I'm having trouble with my windows 7 right now, it's an ultimate version, I just shut it off last night and opened it up this morning. Everything seems to be normal util I loged in to my user. The old things happend after that, only the black screen showed up and an window pop up which shows "my computer" the mouse can be moved regularly.
I tried several ways to get it back to normal:
reboot.
reboot and login to safe mode.
change the resolution and multiple monitor settings.
uninstall and reinstall the graphic driver.
ctrl+alt+del will allow me go to the regular screen which I could go to the task manager, switch user, lock the pc, signoff, change pass word, and reboot or restart etc.
I ended the "dwm.exe" in process which would not work.
That window seems like the only hope I could access the computer which pop up everytime I reboot.
I can use that pop up window to go online and go control panel and all that, I can also run all the program just like normal. Everythings sames normal besides I cannot get the normal screen, no starup, no destop icons, no quick lunch. I could change my background picture, but I cannot use right click on the background.
I think I might of just reset all registry permmissions
