Defrag on Boot - Enable/Disable

A great new feature in Microsoft Windows XP is the ability to do a boot defragment. This places all boot files next to each other on the disk to allow for faster booting. By default this option is enabled but on some builds it is not so below is how to turn it on.

Start/Run/Regedit

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction
Select Enable from the list on the right. Right on it and select Modify. Change the value to Y to enable and N to disable.
Reboot your computer.

Also see HKEY LOCAL MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\Memory Management\PrefetchParameters and EnablePrefetcher = 1 application launch prefetching, 2 boot prefetching
add the numbers.

Also
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\ "Enable"="Y" (Y = defrag will optimize for boot and app launch)

Delete - Can't Delete Files or Folders

Checkpoints/workarounds: Test the Delete after each suggestion.

1. Go to Start/Run/CMD and type in: RD /S [drive:] path
2. Open Notepad and save the (blank) file with the name of the undeletable file. Under save as, navigate to the file, delete.
3. Move the file into a new directory and then delete the directory.

4. Close all open apps. Open a command prompt (Start/Run/CMD) and navigate to the directory with the offending file(s). Then open the Task Manager and click on the Processes tab, select "explorer.exe" under Image Name. Click "End Process".

In the opened Command Prompt, DEL the offending files (DEL *.mpg, DEL mus*.avi, DEL test.wmv, etc.) Once done, go back to the task manager and click on the Applications tab. Click the "New Task..." button. in the dialog, type explorer.exe and click OK.

Note: Could also opt for: ATTRIB -H -R -S filename before the DEL.

5. Or you can use Process Explorer: http://www.sysinternals.com/ntw2k/freeware/procexp.shtml. Use the search function to find every handle that Explorer.Exe has open and close them (right-click on the file and choose 'close handle'). Then delete the file(s) in question.

Desktop.ini

Desktop.ini is used to tell Windows how to display a folder. For example, enabling Thumbnail view creates a desktop.ini file in that folder which amongst other things, tells Windows to add an extra item to the View menu for that folder. Desktop.ini files are also used when you customize folders, change their icons etc.
