Thanks for your answer, I just run SFC /SCANNOW and all fixed. Maybe my HD is getting older, I found the latest download with 0 bytes. I reinstalled Decor8 again but couldn't see the background picture changing, it needed a reboot. :)
I just installed it and didn't see any changes, so I restarted my PC and it showed BSOD so after dumping I restarted again and worked perfectly but too slow the startup, some of my metro applications didn't launch and scrolling became sluggish. So I just uninstalled and restarted, and it showed Drive C: repairing analysis process. Sadly it still is slow the start screen at first start. I don't know what changes did it do to my system, is there
