hi ive just switched my pc on and i get a message saying "explorer .exe-application error"
i cant get my desktop to come on

Try booting into Safe Mode options:

After the power-on and BIOS POST or your Logo screen repeatedly tap the F8 key or hold the Ctrl key before Windows starts.

Choose: Start Last Known Good Configuration

sorry ive tried the above but still the same appears it says"the application failed to initialize properly 0xc0150002" click ok to termiinate the application . is there any possibility of replaciny the explorer if so how cani do this please

Is this a new problem? Were things working OK previously? Any new hardware or software?

Any new updates from Windows Updates? Do you have SP2?

Did you try System Restore from Safe Mode?

If this is a new problem try a System Restore to a point prior to the problem:

start > All Programs > Accessories > System Tools > System Restore


If that fails what is the make and model of the computer? What recovery disks do you have?

this is a clone pc one ive built myself, so no recovery disks , my son was on the net prior to this happening, ive tried to start up on safe mode and tryied to system restore but it also says the same thing same relpy

I would rather not reinstall windows from new which i can do very easily cos i have a lot of saved work on the pc and yes i do have sp2 the only thing it lets me do is boot up safe mode with command prompt but nothing else

A repair install will retain your data and programs as seen here:

Have you tried different restore points?

You can run System Restore from the Command Prompt by typing:

%SystemRoot%\System32\restore\rstrui.exe
