Use a small program to delete any file.

Step 1: Get the Program

Go here
And it is free and under 1mb in size

Step 2: Install It

Double click the unlocker.exe icon
If you get a windows pop up select run.
Follow the instillation.

Step 3: If You Dont Want It to Start With Windows...

But if you don't want to do this or you want it to start go to the next step.
I would recommend downloading one of Lavalys Everest programs (vary useful) but that is not free.
so go to start, run then run msconfig

Then the System Configuration Utility will come up.
Remember when is the System Configuration Utility if you don't know what it is don;t do anything to it.

Go to the Startup tab and look for the UnlockerAssistant.

Click the check so there is no check then select apply then OK.
Then it wont start with windows.

Step 4: Try It Out

Have a file you know is a virus or a so called window component or something like Cannot delete file: Access is denied
There has been a sharing violation.
The source or destination file may be in use.
The file is in use by another program or user.
Make sure the disk is not full or write-protected and that the file is not currently in use.
I am going to test it on a Kodak Easy Share (I only have it to use the Kodak small printer/camera dock)
Kodak is running but i want to delete the EasyShare.exe, but i get an error.
So right click it and select Unlocker.
The Unlocker program will pop up. Then you can select what type of action you want.
Then delete it or what you want.
And Unlocker might want to delete it at start up.
