For starters don't use tuneup utilities. If you PC is properly configured from the start you will never need them. THey generaly do more harm then good. Case in point.
2nd this forum generaly comunicates in english. Change the language before posting images. We have no idea what your problem is since you really have given no description of the problem.
3rd you can't disable explorer.
If the OP's problem, whatever it was, was caused by using Tuneup Utilities, they can simply use TU's rescue function to undo any changes made by TU. By default it makes backups of everything it changes so it should be easy to restore.
In TuneUp Utilities 2010, under "More Functions" simply click "undo changes."
Otherwise, there's always the good old Windows "system restore" utility (assuming it hasn't been disabled) which can be used to restore to an earlier point in time before the problem occurred.
I wont say you can't disable it, but you shouldn't. It could cause many undocumented problems.
I don't see whats wrong with it. :) Is it me or is the image backwards?
