| 3). How to improve on shutdown time ? Close apps automatically & quickly at shutdown tip ** |
|---|
| Open Registry by going to START-RUN and typing REGEDIT. Navigate to HKEY_CURRENT_USER\CONTROL PANEL\DESKTOP and look for AutoEndTasks. On my computer default value is 0. Change it to 1. Thats all. Further more you can reduce the time it takes for Windows to issue kill directive to all active/hung applications. In doing this only constraint that you should make sure exists is that HungAppTimeout is greater than WaitToKillAppTimeout. Change the values of WaitToKillAppTimeout to say 3500 (since default value for HungAppTimeout 5000 and for WaitToKillAppTimeout is 20000) |
| 4). How to login as administrator if you don't see it available tip * |

| 5). Speedup boot up sequence by defragmenting all key boot files tip |
|---|
| Open Registry by going to START-RUN and typing REGEDIT. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction. In right hand panel look for Enable. Right click on it and set it 'Y' for enable. This is the way I have it set on my computer. This will help speedup boot time. |
| 6). Customize Internet. Explorer Title bar tip |
|---|
| This tip won't make your computer any faster but may help personalize your computer experience. Open Registry by going to START-RUN and typing REGEDIT. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Internet. Explorer\Main. In right hand panel look for string "Window Title" and change its value to whatever custom text you want to see. |
| 7). CHANGE TEXT ON XP START BUTTON *** |
|---|
| Step 1 - Modify Explorer.exe File In order to make the changes, the file explorer.exe located at C:\Windows needs to be edited. Since explorer.exe is a binary file it requires a special editor. For purposes of this article I have used Resource Hacker. Resource HackerTM is a freeware utility to view, modify, rename, add, delete and extract resources in 32bit Windows executables and resource files (*.res). It incorporates an internal resource script compiler and decompiler and works on Microsoft Windows 95/98/ME, Windows NT, Windows 2000 and Windows XP operating systems. The first step is to make a backup copy of the file explorer.exe located at C:\Windows\explorer. Place it in a folder somewhere on your hard drive where it will be safe. Start Resource Hacker and open explorer.exe located at C:\Windows\explorer.exe. The category we are going to be using is "String Table". Expand it by clicking the plus sign then navigate down to and expand string 37 followed by highlighting 1033. If you are using the Classic Layout rather than the XP Layout, use number 38. The right hand pane will display the stringtable. We’re going to modify item 578, currently showing the word “start” just as it displays on the current Start button. There is no magic here. Just double click on the word “start” so that it’s highlighted, making sure the quotation marks are not part of the highlight. They need to remain in place, surrounding the new text that you’ll type. Go ahead and type your new entry. In my case I used Click Me! You’ll notice that after the new text string has been entered the Compile Script button that was grayed out is now active. I won’t get into what’s involved in compiling a script, but suffice it to say it’s going to make this exercise worthwhile. Click Compile Script and then save the altered file using the Save As command on the File Menu. Do not use the Save command – Make sure to use the Save As command and choose a name for the file. Save the newly named file to C:\Windows. Step 2 – Modify the Registry !!!make a backup of your registry before making changes!!! Now that the modified explorer.exe has been created it’s necessary to modify the registry so the file will be recognized when the user logs on to the system. If you don’t know how to access the registry I’m not sure this article is for you, but just in case it’s a temporary memory lapse, go to Start (soon to be something else) Run and type regedit in the Open field. Navigate to: HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows NT\ CurrentVersion\ Winlogon In the right pane, double click the "Shell" entry to open the Edit String dialog box. In Value data: line, enter the name that was used to save the modified explorer.exe file. Click OK. Close Registry Editor and either log off the system and log back in, or reboot the entire system if that’s your preference. If all went as planned you should see your new Start button with the revised text.[/b] |
| 8). MAKE YOUR PC FASTER ** |

| When an application fails to respond during shutdown a dialog box is displayed prompting the user to either end it now or to wait. Enabling the value AutoEndTasks will take care of the non-responding application without user intervention. To Implement for All Users [Start] [Run] [Regedit] Registry Key: HKEY_USERS\.DEFAULT\Contr ol Panel\Desktop Now Double click on Desktop Value Name: AutoEndTasks/Data Type: REG_SZ [String Value] // Then Modify/Create the Value Name [AutoEndTasks] according to the Value Data listed below. Rechange the value data of Auto End Tasks as 1 Whinch is marked as 0 Finally Exit Registry and Reboot your system Hope your system works faster |

| 34). The Fix for Grayed Out Boxes |
|---|
| The File Types tab in Explorer's View / Options menu lets you edit most of your file types, but certain settings cannot be changed. The default action for a batch file, for instance, runs the batch file instead of opening it via Notepad or Wordpad. Thus, when you double-click on AUTOEXEC.BAT, a DOS window opens, and the file executes. If you want to change this default action and edit a batch file when you double-click on it, however, the File Types tab does not let you do so; the Set Default button for the file type called MS-DOS Batch File is always grayed out. The button is grayed out because HKEY_CLASSES_ROOT's batfile key contains an EditFlag value entry. Such entries are used throughout the Registry to prevent novice users from altering certain system settings. The binary data in batfile's EditFlag reads d0 04 00 00. If you change this value to 00 00 00 00, you can then change any of the batch file settings. Do not, however, indiscriminately zero out EditFlag; if you do so in a system ProgID such as Drive or AudioCD, it completely disappears from the File Types list. For ProgIDs that are linked to extensions, set all EditFlags to 00 00 00 00. For system ProgIDs, replace EditFlag data with 02 00 00 00. If you wish to have access to some buttons while leaving others grayed out, you must know the function of each EditFlag bit. The last two bytes of data are always zero, but most bits within the first two bytes have a specific effect: • Byte 1, bit 1: Removes the file type from the master list in the File Types tab (select View / Options under Explorer) if it has an associated extension. • Byte 1, bit 2: Adds the file type to the File Types tab if it does not have an associated extension. • Byte 1, bit 3: Identifies a type with no associated extension. • Byte 1, bit 4: Grays out the Edit button in the File Types tab. • Byte 1, bit 5: Grays out the Remove button in the File Types tab. • Byte 1, bit 6: Grays out the New button in the Edit File Type dialog (select the Edit button in the File Types tab). • Byte 1, bit 7: Grays out the Edit button in the Edit File Type dialog. • Byte 1, bit 8: Grays out the Remove button in the Edit File Type dialog. • Byte 2, bit 1: Prevents you from editing a file type's description in the Edit File Type dialog. • Byte 2, bit 2: Grays out the Change Icon button in the Edit File Type dialog. • Byte 2, bit 3: Grays out the SetDefault button in the Edit File Type dialog. • Byte 2, bit 4: Prevents you from editing an action's description in the Edit Action dialog (select the Edit button in the Edit File Type dialog). • Byte 2, bit 5: Prevents you from editing the command line in the Edit Action dialog. • Byte 2, bit 6: Prevents you from setting DDE (Dynamic Data Exchange) fields in the Edit Action dialog. The EditFlags value for Drive, for instance, is d2 01 00 00 in Hex (1101 0010 0000 0001 in binary). Bits 2, 5, 7, and 8 are on in byte 1, and bit 1 is on in byte 2. The EditFlag for batfile is d0 04 00 00 in Hex or 1101 0000 0000 0100 in binary. In this case, bits 5, 7, and 8 are on in byte 1, and bit 3 is on in byte 2. Bits 4, 5, and 6 of byte 2 apply only to actions that are protected. EditFlags with action keys (such as HKEY_CLASSES_ROOT\batfile\shell\open) determine protection. If byte 1, bit 1 of such an EditFlag is 0 (or if there is no EditFlag), then the action is protected. If byte 1, bit 1 is 1, then the action is unprotected. |
