Window registry hack

1.  DisABLe  CMD  {command propmt}

Enabled CMD is a loop hole on your system and anyone can change your password using CMD. Disabled CMD can stop anyone while changing your password and also helps in blocking batch viruses.

• OS  –>  for  XP/VISTA/WIN7
• START  –>  RUN  –>  REGEDIT.
• Navigate to  –>  [HKEY_CURRENT_USER\SOFTWARE\POLICIES\MICROSOFT\WINDOWS\SYSTEM].
• 
• There may be possibility that after MICROSOFT, there will be no subkeys there. So you have to create a new key. Right Click on MICROSOFT –> NEW –> KEY and name it as WINDOWS. Similarly, Right Click on WINDOWS –> NEW –> KEY and name it as SYSTEM.
• Create a new 32-bit DWORD value in SYSTEM. Right Click on SYSTEM –> NEW –> DWORD VALUE and name it as “DisableCMD“.
• Now Double click that value and modify it to 1.
• To Re-Enable CMD, just delete that value or modify its value to 0.

• 0 – (default) enable command prompt and batch files
• 1 – disable command prompt and batch files
• 2 – disable command prompt but allow batch files

• Navigate to  –>  [HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\POLICIES\EXPLORER].
• On the right pane see the value “NoDriveTypeAutorun“. If value doesn’t exists then create new DWORD value. Right Click on EXPLORER –> DWORD VALUE , and name it “NoDriveTypeAutorun“.
• Double Click that value  and modify it to 95 from 91.
• 20 – To disable AutoRun on CD-ROM drives 4 – To disable AutoRun on removable drives 8 – To disable AutoRun on fixed drives 10 – To disable AutoRun on network drives 40 – To disable AutoRun on RAM disks 1 – To disable AutoRun on unknown drives.
• If you want to disable Autorun on a combination of drives, you’ll need to calculate sum of the values. For example, if you want to disable Autorun on CD-ROM drives and removable devices, you’ll need to set the value to 20+4=24.

3. DisABLe  W!NDoWs  FiReWaLL

• START  –>  RUN  –>  REGEDIT.
• Navigate to  –>  [HKEY_LOCAL_MACHINE\SOFTWARE\POLICIES\MICROSOFT\WINDOWSFIREWALL\STANDARDPROFILES]. and also to  –>  [HKEY_LOCAL_MACHINE\SOFTWARE\POLICIES\MICROSOFT\WINDOWSFIREWALL\DOMAINPROFILES].

8. aLLoW  LaPToPs  to  EnTeR  PoWeR  SaV!nG  sTaTe

Some laptops’ processors might not be able to enter their power-saving state, even when they’re idle, because USB polling fools the processor into thinking the laptop is active. Your system polls your USB ports once every millisecond to see whether a device is present. So, even if a device isn’t present, it continues polling. The problem is that some laptop processors won’t go into their power-saving state because the constant polling makes them think the laptop is active.

With a Registry hack, you can increase the polling interval from the default of one millisecond, letting the processor enter its power-saving state.

• START  –>  RUN  –>  REGEDIT.
• Navigate to  –>  [HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\CONTROL\CLASS\{36FC9E60-C465-11CF-8056-444553540000}000].
• Create a new DWORD value named as “IdleEnable“. Double Click that value and modify value data to number between 2 and 5. This will set the polling intervals in milliseconds.
• If there are Additional sub-keys, like 0000. If there is 0001, 0002, 0003 and so on…… repeat that procedure and create DWORD value “IdleEnable” in each of these keys.
• I have 28 keys…. so don’t take your hands off the keyboard. To make this Hack, you have to make edits in all of the keys.
• Reboot is necessary for changes to take effect. There is also possibility that you might to try different values untill you find the correct one to work for you.

• START  –>  RUN  –>  REGEDIT.
• Navigate to  –>  [HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\CONTROL\SESSIONMANAGER\
  MEMORYMANAGEMENT].

11.  cHaNGe  DeFauLT  TTL vALue

Default TTL determines the time in seconds and number of hops packet lives (every hop reduces it by atleast by 1). While it doesn’t directly affect speed, a larger value increases amount of time it takes for a packet to be considered lost, discarded and retransmitted. A value that’s too small can cause packets to be unable to reach distant servers at all.

• START  –>  RUN  –>  REGEDIT.
• Navigate to  –>  [HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES\TCPIP\PARAMETERS].
