Setting the Minimum Password Length :
1.Open RegEdit
2.Go to
HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows\ CurrentVersion\ Policies\ Network
3. Now, choose the Edit/New/Binary value command and call the new value MinPwdLen. Press Enter twice and Assign it a value equal to your minimum password length.
Add\delete programs to run every time Windows starts :
You can start or stop programs from executing at boot up by adding or deleting them to/from the run Keys in the Registry. Windows loads programs to start in the following order; Program listed in the Local Machine hive, then the Current User hive, then theWin.ini Run= and Load = lines. then finally programs in your Start Up folder.
To add or remove programs in the Registry :
1.Open RegEdit
2.Go to the desired Key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows \CurrentVersion \Run
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows \CurrentVersion \RunServices
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows \CurrentVersion \Run
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows \CurrentVersion \RunServices
3. Add a new String Value and name it anything you like
4. For the value data, enter the path and executable for the program you want to run.
By adding the value to the HKEY_CURRENT_USER hive instead allows the program to start only when that user is logged on.
If you add the value to the RunOnce key the program will run once and be removed from the key by Windows.
Removing the Shortcut Icon Arrows
1.Open RegEdit
2.Open the Key HKEY_CLASSES_ROOT
3.Open the Key LNKFILE
4.Delete the value IsShortcut
5.Open the next Key PIFFILE
6.Delete the value IsShortcut
7.Restart the Windows
Turn Off Window Animation
You can shut off the animation displayed when you minimize and maximize Windows.
1. Open RegEdit
2. Go to HKEY_CURRENT_USER\Control panel \Desktop\ WindowMetrics
3. Create a new string value "MinAnimate".
4. Set the value data of 0 for Off or 1 for On.
Changing your Modem's Initialization String :
1.Open RegEdit
2.Go to
HKEY_LOCAL_MACHINE\System\CurrentControlSet \Services \Class \Modem \0000 \Init
3.Change the settings to the new values.
Removing Programs from Control Panel's Add/Remove Programs Section :
If you uninstalled a program by deleting the files, it may still show up in the Add/Remove programs list in the Control Panel.
In order to remove it from the list.
1.Open RegEdit
2.Go to HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows\ CurrentVersion\ Uninstall
3.Delete any programs here.
If you have a problem locating the desired program open each key and view the DisplayName value.
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.
Protection on system files :
To enable protection on system files such as the KnownDLLs list, add the following value :
1. Open RegEdit
2. HKEY_LOCAL_MACHINE\System\CurrentControlSet\ Control\ SessionManager
3. Create the a Dword value and name it "ProtectionMode "
4. Set the Value to1
