Enabling Task Manager disabled by Administrator or Virus [Trick: Windows]

Windows Task Manager is used to view details about processes running on your computer. It can be used to terminate programs that are misbehaving. Most spyware and viruses disable it to prevent themselves from being closed through it. Some administrators also disable Task Manager to prevent other users from closing important security programs like antiviruses and anti-malwares.

In such situations, running the Task Manager will give the "Task Manager has been disabled by Administrator" error. However, there are some tricks you can use to re-enable task manager and close those harmful programs manually.

Enable Task Manager from Registry in Windows10, Windows 8/8.1, 7, XP or Vista

Registry Editor can be used to modify registry keys which tell Windows how it should work. A simple registry modification can be used to bypass the Task Manager block. To do so, just follow the steps:-
  1. Click on Start. Go to Run. If you use Windows 10, Windows 8/8.1, Windows 7 or Windows Vista, go to Search.
  2. Type regedit and press Enter. Registry Editor will start. If Registry Editor is also disabled, you will first need to enable registry editing.
  3. Through the left hand navigation pane, navigate to HKEY_CURRENT_USER\Software\Microsoft\ Windows\ Current Version\Policies\System. If the System key is not there, you will need to create it.
  4. In the work area, locate "DisableTaskMgr". If this value is not there, you will need to create a new DWORD value called DisableTaskMgr. Double click on it. A window will pop up.
  5. Enter its value data as 0 and press OK.
  6. Close Registry Editor.
  7. If Task Manager is still disabled, restart your PC.

Enable Task Manager from the Group Policy Editor (Gpedit.msc)

Group Policy Editor is a feature in Windows which is used to edit local policy settings. It can also be used to enable Task Manager. To do so, just follow the steps given below:-
  1. Open Start Menu. Windows XP users click on Run. Windows 10, Windows 8/8.1, Windows 7 and Vista users, go to Search.
  2. Type gpedit.msc and press Enter. Group Policy Editor Window will show up.
  3. From the navigational pane at the left hand side, go to: User Configuration>Administrative Templates>System>Ctrl+Alt+Del Options.
  4. In the work area, double click on "Remove Task Manager" and set its value to Disabled or Not Configured.
  5. Restart your Computer or Log Off and Log back On to apply the changes.
Note : Group Policy Editor is not available on home editions of Windows.

Enable Task Manager by Running a CMD Command

Command Prompt can also be used to directly enable Task Manager.
  1. Open Notepad.
  2. Copy the code given below and paste it.
  3. REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System  /v  DisableTaskMgr  /t REG_DWORD  /d /0 /f
  4. Save the File as TaskManager.bat.
  5. Run TaskManager.bat as Administrator if you use Windwos10, Windows 8/8.1, Windows 7 or Windows Vista. In Windows XP, simply open the file. A command prompt window will flash for a second and then disappear indicating successful execution.
  6. If Task Manager is still not available, restart your PC.
The tricks mentioned will work on Windows 10, Windows 8/8.1, Windows 7, Windows XP and Windows Vista

Recover Deleted files : Recuva

Have you ever deleted a file that you did not wish to and wanted to recover it but did not find it in the recycle bin? You probably deleted it permanently with Shift+Delete or emptied the Recycle Bin. Now what? Don't worry, you may still have a chance to get it back.

Q. But how do the software undelete deleted files?

When files are deleted, Windows does not delete them from your hard disk. It marks the storage space as empty for new data to be written and deletes the index entry that tells the location of those files. Unless, new files are written on that space, the deleted files are still recoverable. That's what allows these software to recover deleted files.
Recuva [Free version available]

Recuva offers a wizard based interface to unerase files. Recuva offers scanning deleted files based on their type (music, pictures, videos etc.). It also allows deep scanning in case a file you deleted is unrecoverable via normal search. Recuva offers securely deleting files. Recuva also has a portable version that you can keep in your flash drive.

This recovery software support recovery from memory sticks, digital camera cards and MP3 players. This also support undeleting all types of pictures, software, movies and documents from both FAT and NTFS formatted drives. This tool work on Windows 10, Windows 8/8.1, Windows 7, Windows Vista and Windows XP.

Some important tips to increase the chances of getting your deleted files back:-

1) When a file is deleted accidentally on a storage device, make sure that you don't do anything on it as doing that would increase the chances of new data being written over your deleted files, which would make file recovery impossible.

2) If you have deleted files on your main computer (the one you are using right now), do not use it. Keep it running and go to another computer, download Recuva . Then plugin the flash drive in your current system and perform file recovery.

3) If one software fails to recover your deleted file, it does not mean that another one wouldn't recover it too.

Change File format FAT32 to NTFS Without Formatting

If you have a flash drive or an external hard drive that currently has FAT32 file system and you want to change it to NTFS, because FAT32 does not support handling large files (over 4GB) but there is just one problem, you don't want to lose your saved data.
Then this is right place for you, You can achieve seamless transition from FAT to NTFS without involving any data loss.
There are many software's that support File Format conversion but the Convert command is one of the easiest ways to do so. Follow the steps below to know how:-

Important: While this method works perfectly, I would still advise you to backup your data in case  anything goes wrong.


FAT 32 to NTFS Conversion Steps :


1) Go to Computer, and note the name of the drive whose file system you wish to convert.
2) Click on Start.
3) Type cmd in the search bar if you use Windows 7, Windows 8/8.1, Windows 10 or Windows Vista. If you use Windows XP, click on Run and then execute cmd.
4) Execute "chkdsk d: /f " (without quotes) where d is the letter of the drive to undergo conversion. This checks the drive for errors and fixes them automatically.
5) Execute "Convert d: /FS:NTFS" (without quotes). d is again the letter of the drive to be converted.
6) The command prompt will start the conversion process and after a few minutes, CMD will say that conversion was successful.
7) You can check it in the properties of the drive through right click<Properties.

This command can also be used to convert FAT16 disks and works on Windows 8/8.1, Windows 10, Windows 7, Windows XP and Windows Vista.
Important : This method cannot be used to reconvert NTFS file system back to FAT32. To reconvert back to FAT32, you will need to format the entire drive which will definitely cause data loss.

Shutdown Your Computer using Command Prompt

Most of us shutdown our computers using the power button given in the Start menu. Some of us use the physical power button on our machines. Very few people actually use other means of shutting down a computer and even less is the number of people who use the command prompt to shutdown a computer.

A computer running Windows (XP, Vista, 7, 8 or 8.1, 10) with the command prompt working perfectly, i.e. not disabled by a virus.

Initial Steps
1) Press Windows Key + R.
2) Enter CMD and press Enter.

This will start the command prompt. Follow the instructions below depending on what you want to do to your machine.

Shutdown Your Computer
Type "shutdown -s" without the quotes in the command prompt and press Enter. Shutdown is the command being executed and the switch -s tells the computer to shutdown.

Restart your Computer
Type "shutdown -r" in the command prompt and press Enter. In this case, the command switch -r is telling the computer to restart after shutdown.

Log Off the Current User
Type "shutdown -l" in the command prompt and press Enter. The -l command switch tells the computer to log off.

Hibernate a Your Computer
Type in "Rundll32.exe Powrprof.dll,SetSuspendState" without the quotes and press Enter. Your computer should hibernate, if it does not, then you must enable hibernation to do this from control panel.

Shutdown your computer after a specific time
Type "shutdown -s -t 60" to shutdown your computer after 60 seconds. Upon executing this, a countdown timer displaying a warning message will be shown. This command uses the -t command switch followed by a variable (which is 60 in this case) which represents the number of seconds after which the computer will shutdown.

Display a Message containing the reason for shutdown
Type shutdown -s  -t 500 -c "I am tired. I don't want to work anymore." (with the quotes) in the Command Prompt and press Enter. The -c switch is used in the code to give the reason for shutting down and what is followed in quotes will be displayed in the dialog box as the reason. This can be used to display all sorts of funny messages.

Create Bootable USB Drives to Install (Almost) Any OS : Rufus

Rufus is small in size (nearly 600 KB) and claims to be faster at creating bootable USB drives than most applications of its type. Rufus is also portable which means that you need not install this software to use it. Just double click on the executable file and the application will start working. Rufus also allows you to add fixes to use your bootable flash drives on older computers having BIOSs which do not support booting from them.

However, Rufus can only create bootable flash drives from ISOs meaning you need to have an ISO image of the CD or DVD of the OS of your choice.

I do not think this should be too much of a problem considering how easy it is to create ISOs from DVDs and CDs.

How to use Rufus?

1) When you start Rufus, the first option that you will see is Device:. It contains all your connected USB drives. If you plug in a USB drive after starting Rufus, the drive you have connected will shortly be available here.

2) You will not need to modify the Partition Scheme and target system type, as the default choice is suitable for making the USB drive work on both UEFI and legacy BIOS computers.

Rufus on WIndows 10

3) Change the file system from FAT32 to NTFS from the dropdown menu. This is the file system with which your USB drive will be formatted with. Do note that older computers will not boot from a flash drive formatted as NTFS. Do not modify the cluster size. Enter the name you want for your USB device in the Volume label box.

4) Check the Create a bootable disk using checkbox if it is not already checked. In the dropdown menu next to it, select ISO image. Click on the button right to it to locate your ISO image.

Do note that Rufus will format your USB drive deleting everything on it before making it bootable. So, make sure that it does not contain any important data.

5) Click on Start to format your USB drive and extract all files of the ISO to it.

To install the OS, restart your computer and select your USB device as the primary boot option in the BIOS boot menu.

Rufus works on all the latest versions of Windows and can be used to extract the following ISOs to a bootable USB drive:-

Arch Linux, Archbang, BartPE/pebuilder, CentOS, Damn Small Linux, Fedora, FreeDOS, Gentoo, GParted, gNewSense, Hiren's Boot CD, noppix, KolibriOS, Kubuntu , Linux Mint, OpenSUSE , ReactOS, rEFInd, Slackware, Tails, Trinity Rescue Kit, Ubuntu, Ultimate Boot CD, Windows XP (SP2, SP3), Windows Server 2003 R2, Windows Vista, Windows 7, Windows 8, Windows 8.1, Windows 10 and many more.

Encrypt Files or Folders in Windows: Free

With hackers becoming more and more sophisticated, most of us are worried about the safety of personal data. There are many options available to protect data but none comes close to encryption in terms of safety offered. There are easy to use methods that allow to encrypt important files and folders in Windows.

Encrypting files in Windows using the Encrypting Files System (EFS)

Windows offers an inbuilt encryption method called EFS to protect sensitive data from unwanted users. EFS can be used only on hard drives formatted as NTFS and on professional and premium editions of Windows 10, Windows 8.1, Windows 8, Windows Vista or Windows XP. Home editions of Windows do not support this.

To encrypt files with EFS, follow these steps:-
  1. Right click on the file or folder you want to protect and click on Properties at the bottom of the menu.
  2. This will bring up the Properties window. In this window under the General tab, click on Advanced.
  3. In the Advanced attributes window, tick on Encrypt contents to secure data option.
  4. Click OK and Apply.
If the file is encrypted successfully, its name will generally be visible in green font.

If you encrypt files and folders with EFS, it would not change how you access those files and folders. You would still be able to read, modify and delete those files as long as you are logged into the user account that encrypted those files. However, other users from would not be able to do this. For example, if you carry the encrypted file in a flash drive, you would not be able to access it from other computers. To access it from other computers, you will need your encryption key.

Important : 
Make sure that you backup your encryption key when Windows prompts you to do so. It will be required in case you want to access the encrypted files from a different user account or from a different computer.

To back up your encryption key, click on the Back up now option in the pop up that comes when you first encrypt a file or folder. Then, click Next on the window titled Certificate Export Wizard. Enter a password for your certificate (make sure it is tough but also easy to remember), choose a location to save it, give it a name and click Finish.

In case Windows does not prompt you to back up your encryption key, you can back it up from the File Encryption Certificates manager. Since, EFS relies on your user account to give access to protected files, it is important to choose a strong password for your Windows user account.

EFS is relatively quick and hassle free but not totally secure as Windows stores an unencrypted version of protected files in the temporary folder (when you access them) which can be easily accessed by any experienced computer user. To overcome this weakness, ensure that you clean up your temporary files with the Disk Cleanup utility every time you access your protected files.
