Other miscellaneous tweaks

Adding Resize option to images

This hack will allow any JPG file to be resized from the context-menu. First: get ImageMagick toolkit for windows from This site and install it. Next: create a cmd file (a batch file for windows NT,XP, Vista) with the following contents:

@echo off
set CONVERTPATH="C:\Program Files\ImageMagick-6.3.7-Q16\"
if "%2"=="" goto NoSizeArgument
set SizeVariable=%1
set FileOnly=%~n2
set FileExtension=%~x2
set FilePath=%~p2
set DriveLetter=%~d2
goto DoConvert
:noSizeArgument
set SizeVariable=1024
set FileOnly=%~n1
set FileExtension=%~x1
set FilePath=%~p1
set DriveLetter=%~d1
:DoConvert
%CONVERTPATH%convert.exe -resize "%SizeVariable%x%SizeVariable%>" "%DriveLetter%%FilePath%%FileOnly%%FileExtension%" "%DriveLetter%%FilePath%%FileOnly%_%SizeVariable%%FileExtension%"
echo resized %FileOnly%%FileExtension% to %FileOnly%_%SizeVariable%%FileExtension%

Let's say we name this file C:\Program Files\ImageMagick-6.3.7-Q16\convert1024.cmd Now we have the command at hand to resize an arbitrary image to max dimensions of 1024x1024, keeping the aspect ratio intact. Here's how we add this command to the context menu:

1. Open any folder (e.g. My Documents)
2. Go to Tools | Folder Options...
3. On the opened dialog, go to the File Types tabsheet
4. Select in the "registered file types" the file type you want to add the resize option for. E.g. choose JPG for the most commonly used file format.
5. Click the 'Advanced' button.
6. In the dialog that just opened, click the 'New...' button
7. In 'Action' fill in the description of the resize action. E.g. enter 'Re&size to 1024x1024 max'
8. Click the browse button, and navigate to the cmd file we created in the beginning. Select it, and Click OK to confirm it all.
9. Close the File Types dialog, and presto: you now have a resize command at the ready.

Internet software tweaks

Multiple instances of Yahoo! messenger

Description: The default behavior of Yahoo! messenger is such that only one instance can run at one time. But sometimes logging in from multiple IDs maybe required.

Registry to run multiple yahoo messenger instances

Key	HKCU\Software\yahoo\pager\test
Value Name	REG_DWORD
Data Type	Plural
Data	2

Hardware Tweaks

Fixing error messages

CD-ROM Drive Related Issues

There is a bug in Microsoft Windows XP and Microsoft Windows Vista, that causes the operating system to ignore the presence of installed devices and drivers, following a reboot of the system. An error message occurs as follows following reboot:

Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

When this error occurs, the CD-ROM drives do not show as available, so it will not be possible to use the drives, even though the CD-ROM drives may have been operating normally during the previous session.

Uninstalling the device does not fix this error

Uninstalling the drive using the device manager and rebooting the computer does not resolve this error.

Affected Systems

Microsoft Windows XP Microsoft Windows Vista

Resolution

In order to resolve this issue, it is necessary to edit the CD-ROM drive class registrykey, using the registryeditor, as follows:

   * HKEY_LOCAL_MACHINE
         o SYSTEM
               + CurrentControlSet
                     # Control
                           * Class
                                 o {4D36E965-E325-11CE-BFC1-08002BE10318}

Remove any of the following registry entries against the CD-ROM drive class registrykey:

   * UpperFilters
   * LowerFilters
   * UpperFilters.bak
   * LowerFilters.bak

It is now necessary to reboot the computer in order for the CD-ROM drives to be made visible.

HKEY CLASSES ROOT

The *Microsoft Windows Registry* is divided into sets and subsets. The HKEY_CLASSES_ROOT set contains the following subset entries:

• The file extension subset types:
• The class identifiers
• The typelib entries
• Package and vendor specific entries
• Compatibility entries
• Installer entries
• Virtual store entries

HKEY LOCAL MACHINE

Autologon

In the case of a Windows family with one (admin) user and no password, his desktop may open automatically after the boot: that's the autologin system.

To set it on the other configurations (eg: Windows professional), just execute a .reg file with the following keys:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
 "AutoAdminLogon"="1"
 "DefaultUserName"="TheUserToUse"
 "DefaultDomainName"="TheUserDomain"
 "DefaultPassword"="TheUserPassword"

Beware: the password will become readable (in Regedit) by anyone who touches the machine.

Changing program installation directories

With Cygwin you can list the registry entries concerning installation directories with one of these commands:

regtool list -v /HKEY_LOCAL_MACHINE/SOFTWARE/Wow6432Node/Microsoft/Windows/CurrentVersion | grep Program

or

regtool list -v /HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion | grep Program

The output should be something like:

SM_ConfigureProgramsName (REG_SZ) = "Set Program Access and Defaults"
CommonFilesDir (REG_SZ) = "C:\Program Files (x86)\Common Files"
CommonFilesDir (x86) (REG_SZ) = "C:\Program Files (x86)\Common Files"
CommonW6432Dir (REG_SZ) = "C:\Program Files\Common Files"
ProgramFilesDir (REG_SZ) = "C:\Program Files (x86)"
ProgramFilesDir (x86) (REG_SZ) = "C:\Program Files (x86)"
ProgramFilesPath (REG_EXPAND_SZ) = "%ProgramFiles(x86)%"
ProgramW6432Dir (REG_SZ) = "C:\Program Files"

Changing the user home directory

The registry key that has to be changed is

HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS NT\CurrentVersion\ProfileList\ProfilesDirectory

The default value is %SystemDrive%\Users and can be changed to a specific path (without %SystemDrive%), like for instance U:\usr\unix\cygwin\home.

To move the remaining content of C:\users you have to open "Start -> Control Panel -> Folder Options" and select the "Show Hidden files, folders, and drives" option in the "View" tab. This will make a "default" subdirectory visible in the C:\users directory. Now most of the content of C:\users can be copied to the new destination (but not all the files of the active user).

For the "default" and "public" subdirectories the following keys need to be set to point to the new location:

HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS NT\CurrentVersion\ProfileList\Default

HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS NT\CurrentVersion\ProfileList\Public

On Windows 7 (and probably other versions) the procedure does only affect accounts created after changing the ProfilesDirectory setting. For all other accounts the location of the Desktop, Documents and other standardized directories have to be changed manually, which is, of course, also possible without changing the registry. These locations are: Contacts, Desktop, Documents, Downloads, Favorites, Links, Music, Pictures, Saved Games, Searches, Videos and Virtual Machines.

For accounts created earlier one should also use %windir%\system32\compmgmt.msc (Computer Management) to change the location of the home folder local path under the "Profile" tab. This will, however, not automatically change the location of Desktop, Documents and other standardized directories.
