Windows Registry Hack

Before making any changes to Windows Registries Plzzzzzzz, Back-up uR registries. To do this –

• Open “RUN” and type “regedit” without quotes.

• Now at Top-Left, File –> Export, & then save as any name you want lik “ron”,  without quotes.

• The Windows Registry keys and values supports Camel-Case rule. It means like first alphabet of word must be in capital letters and no spaces is provided between two words. Ex –> FirstCut. But i have mentioned keys name already as how they should be named, so you should name them same as i name them.

1.  Swapping  Of  Mouse  BuTToNs  BeFoRe  LoGiN

• OS –> for XP/VISTA
• START  –> RUN  –> REGEDIT.
• Navigate to –> [HKEY_USERS\.DEFAULT\CONTROLPANEL\MOUSE] and set SwapMouseButtons.
• Also note, there is a separate registry entry for swapping the mouse buttons per user. That setting would be be triggered after the login process.

2. ChanGe  iMaGe  ThumbNail  SiZe

• OS –> for XP/VISTA/WIN 7
• START  –>  RUN  –>  REGEDIT.
• Navigate to –> [HKEY_CURRENT_USER\SOFTWARE\MICROSOFT\WINDOWS\CURRENT VERSION\EXPLORER].
• Look for an entry on right side for ThumbnailSize, Double click on it and change the value.
• Can’t find it? Then right-click on Explorer and select New > DWORD Value and type “ThumbnailSize” for the name and press Enter.
• Double click ThumbnailSize and set the value to a number between 32 and 256. The higher the number, the larger the image thumbnails.

If you can’t find any of these registry keys or values try HKEY_LOCAL MACHINE instead. This tweak will work in Vista and XP also.

3.  Disable  USB  pOrTs

• OS  –>  for XP/VISTA/WIN7
• START  –>  RUN  –>  REGEDIT.
• Navigate to  –> [HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES\USBSTOR]
• Double Click –> Start , and change the value from 3 to 4.

• Create a NEW DWORD value in both of these locations called as “NoViewOnDrive“.
• Add these decimal numbers to hide the drives  –>  A:1, B:2, C:4, D:8, E:16, F:32, G:64, H:128, I:256, J:512, K:1024, All Drives:67108863.
• For example,to hide drive A and drive C, you would add 1(for A)+4(for C) to get 5, and the value of NoViewOnDrive should be set to 5.To disable all the drives, set the value to 67108863.
• You’ll need to restart Windows to see the effect take place.

5.  EdiT  StaRt-uP  ProGRam  LisT

Many of the programs that run at the boot time do not figure in the Startup folder. If you want to block more than one application from loading at the startup, you will need to manually block of those individually through their preference settings. Tedious and time consuming. This hack can help you do the same in one go.

• OS  –>  for XP/VISTA/WIN7
• START  –>  RUN  –>  REGEDIT.
• Navigate to  –>  [HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\RUN] and  also Navigate to  –>  [HKEY_CURRENT_USER\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\RUN].

18. 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.

19.  PLaCe  W!NDoWs  KeRNeL  !NTo  rAm

Perform this hack only if the system has 256MB or more of installed RAM!!!!!

It’s a given that anything that runs in RAM will be faster than an item that has to access the hard drive and virtual memory. Rather than have the kernel that is the foundation of XP using the slower Paging Executive functions, use this hack to create and set theDisablePagingExecutive DWORD to a value of 1.

• START  -->  RUN  -->  REGEDIT.

28. Create your own Run Command 

I talk a lot about Windows, and using the “Run” command is a large part of it. It is a simple and easy method of accessing programs quickly. If you happen to want to make a shortcut to an application your own way, guess what, you can!

Let’s do it:

Step 1: Go to “Start,” “Run,” (told you we use it a lot) and type regedit.

Step 2: Navigate to the following:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Apps Path

Step 3: Create a new folder/key under Apps Path. (Right-Click Apps Path and click “New,” “Key.”)

Step 4: Title the new folder/key the name of the application, e.g. firefox.exe.

Step 5: Right-Click the default string value (the thing automatically created in your new folder) and click Modify.

Step 6: Change the value to the path of the executable you are attempting to run. E.g. C:\Program Files\Mozilla Firefox\firefox.exe.

Step 7: Create a new “String Value” by right-clicking under the default value (the thing we just edited) and select “New,” “String Value.” Name it Path and enter the value as the same path you previously entered.

Step 8: Done! Now, all you need to do is go to “Start,” “Run,” and type the name of your command!

34. EnaBLe  NT  Hash  to  IncReaSe  WinDoWs  PassWorD  SeCuriTy

Instead of storing your user account password in clear-text, Windows generates and stores user account passwords by using two different password representations, generally known as “hashes.”

When you set or change the password for a user account to a password that contains fewer than 15 characters, Windows generates both a LAN Manager hash (LM hash) and a Windows NT hash (NT hash) of the password. These hashes are stored in the local Security Accounts Manager (SAM) database or in Active Directory.

The LM hash is relatively weak compared to the NT hash, and it is therefore prone to fast brute force attack. Therefore, you may want to prevent Windows from storing an LM hash of your password

·         OS  –>  for XP/WIN Server 2003

·         START  –>  RUN  –>  REGEDIT.

·         Navigate to  –>  [HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\CONTROL\LSA].
