Fixing “Task Manager is Disabled by your Administrator” That's a very common problem for Windows users. Many times when you try to open Task Manager, you find that "Task Manager" option has been grayed out: Also when you try to run it by typing "taskmgr" in RUN dialog box, Windows shows following error message: Task Manager has been disabled by your administrator. There might be 2 possible reasons behind this problem:
Your system administrator applied the restriction using Registry Editor or Group Policy Editor. Your system has been infected with virus and it has disabled the Task Manager.
If you are already the Administrator of the system, then your system is most probably infected. Now if your system in not infected or you have successfully removed the virus, then you can follow these simple steps to enable Task Manager again: 1. Type regedit in RUN dialog box or Startmenu Search box and press Enter. It'll open Registry Editor. 2. Now go to following keys one by one:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System HKEY_USERS\.default\Software\Microsoft\Windows\CurrentVersion\Policies\System and look for a DWORD value "DisableTaskMgr" in right-side pane. If you find it, delete it. 3. That's it. Now Task Manager will be enabled.
Enabling Folder Options and Registry Editor Many times Windows users face a common problem. The"Folder Options" in "Tools" menu is not visible. Even It can't be accessed from Control Panel. Also "Registry Editor" is disabled. If you are also facing this problem, then you have come to right place. Follow the simple steps mentioned in this tutorial and your problem will be solved: 1. If Folder Options is disabled but Registry Editor is still working in your system, then you can enable Folder Options by editing Windows Registry. Type regedit in RUN dialog box and press Enter. it'll open Registry Editor, now go to following keys:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\Policies\Explorer In right-side pane, check whether a DWORD value namedNoFolderOptions exists or not? If it exists, delete it. 2. But sometimes Registry Editor is also disabled. Whenever you try to openregedit, Windows will show following error message:
Registry Editor has been disabled by administrator. Its a symptom of “RONTOKBRO” Trojan.
3. If its not a trojan problem and someone intentionally has disabled it in your system, then you can enable it again by following any of these methods: a. Type gpedit.msc in RUN dialog box and goto:
User Configuration -> Administrative Templates -> System in right-side pane, set "Prevent access to Registry editing tools " to either Not Configured or Disabled. b. Just type following in RUN dialog box and press
:
REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f Now after enabling Registry Editor, you can re-enable Folder Options by following methods mentioned in 1st or 2nd steps.
Resetting Forgotten Password 1st Method:
The first thing which you check if you forget login password. When we install Windows, it automatically creates an account "Administrator" and sets its password to blank. So if you have forget your user account password then try this: Start system and when you see Windows Welcome screen / Login screen, press ++ keys twice and it'll show Classic Login box. Now type"Administrator" (without quotes) inUsername and leave Password field blank. Now press Enter and you should be able to log in Windows. Now you can reset your account password from "Control Panel -> User Accounts ". Same thing can be done using Safe Mode. In Safe Mode Windows will show this in-built Administrator account in Login screen. 2nd Method:
Windows XP and further versions also provide another method to recover forgotten password by using " Reset Disk". If you created a Password Reset Disk in past, you can use that disk to reset the password. 3rd Method:
If the above mentioned tricks don't work, then try following trick which is actually a loophole in Windows XP Setup and a big security hole: A. Boot using Windows XP Setup CD and follow the instruction like Accepting EULA, etc. B. When it asks to repair your existing Windows installation, accept it and press "R" to run the repair. C. Setup will start repairing your Windows and will start copying files, etc. D. After a few minutes setup will restart your system and when it restarts don't press any key when it shows "Press any key to continue..." otherwise Setup will start from the beginning. Don't press any key and setup will resume where it left. E. Now it'll start doing other tasks and will show a small progressbar with a few details in left side.
F. Look carefully at the details and when it shows I"nstalling devices", press +F10 keys in your keyboard. G. It'll open a Command Prompt window. Now typenusrmgr.cpl and press . H. It'll open the same "User Accounts" window which you see in Control Panel. I. Now you can remove or reset any account password without any problem. 4th Method:
There are many 3rd party utilities which claim to recover forgotten Windows password: Windows Geeks Lost Forgotten Password Service:
Windows Geeks have a program that works instantly to remove any lost or forgotten password. With this program you can get back in very quickly: Emergency Boot CD:
EBCD is a bootable CD, intended for system recovery in the case of software or hardware faults. It is able to create backup copies of normally working system and restore system to saved state. It contains the best system software ever created, properly compiled and configured for the maximum efficient use. You may download image builder utility which creates image of bootable CD-ROM (.ISO file), plus basic set of system tools. When the image is ready, write it to CD-R or CD-RW, and then everytime you'll need convenient and powerful system tools they'll be just at hand. It is easy to customize the disk for your needs. You can include to CD any program you like, or remake the structure of CD completely. All you need is to change a few lines in configuration XML files. Offline NT Password & Registry Editor:
This is a utility to reset the password of any user that has a valid (local) account on your NT system. You do not need to know the old password to set a new one. It works offline, that is, you have to shutdown your computer and boot off a floppydisk or CD. It'll detect and offer to unlock locked or disabled out user accounts. It is also an almost fully functional registry editor. Windows XP Login Recovery:
Login Recovery is a service to reveal user names and recover passwords for Windows NT, 2000, XP, 2003 and Vista. As long as you have physical access to the computer, your passwords can be recovered. Ultimate Boot CD (UBCD):
Ultimate Boot CD runs independently of any operating system. It will boot from any Intel-compatible machine, regardless of whether DOS/Windows/Linux/BeOS is installed on the machine. However, you do need an operating system and a ISO-capable CD writer software to create the Ultimate Boot CD from the downloaded ISO image file. 5th Method:
If all fails, then simply reinstall Windows and create new accounts. To recover lost data, you can use Data recovery tools available on net but the chances will be very low to get data back. That's all we can suggest. If you have any other method / tool, feel free to post here.
