Computer IconI will assume that many of you have to solve computer’s problems every day.

But, imagine having a list of devil hacks you can use to punish people.

Maybe you are tired to solve others problems, or you want to have fun. If you are in either of these positions this is your post.

1. Cut access to Internet Web Pages.

You can cut internet from certain hours using the following post:

How To Control Access to Specific Website

But if you just want to cut access to a Web, for example www.google.com:

Click on Start Menu, Accesories, look for Notepad, right-click and select “Run as administrator”.

Notepad Run As Administrator

Select File, Open…, and go to %SystemRoot%\system32\drivers\etc\ folder. Select open all files, you just add the following line and click save: www.google.com

Hosts blocking google

2. Disallow Software Installation

This technique will make it impossible to install any program by a user no matter if you are administrator or not.

Press Winkey + R, type services.msc and press Enter.

Look for Windows Installer:

Windows Installer Properties

Select Stop and disable the service.

Windows Installer Disabled

Next time, you try to install something the following message appears, “The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance.”

Windows Installer Service Message

You can be even more evil and don’t let any user to change this property but at least for now is enough.

3. Send a message to recall who the boss is.

Why not recalling everyone who is the master?  For this we are going to use only one command line.

First open a Command Prompt with administrator rights.

Command Prompt Run As Administrator

Type schtasks /st 12:00 /create /SC daily  /TR “msg * I’m your boss” /TN taskname and press Enter.

schtasks Im your boss

Now the PC will recall at 12:00 everyday who is the person in charge.

4. Disallow a Specific Program from Starting

You can do this with parental controls, but it cannot be used for administrators.

So, how to not let someone with administrator rights start a program?

Press Winkey + R, type gpedit.msc and press Enter.

For this example we are going to limit the access to Microsoft Office Excel 2003.

Go to Local Computer Policy, Windows Settings, Security Settings, Application Control Policies, AppLocker, Executable Rules.

On the right pane, right-click and “Create default rules”.

create default rules

Right click, and “Create new rule”, action: deny, select Path:

App locker path

Next, select Browse Files, you can browse folders too.

You have to look for Microsoft Excel executable, now you only have to click next.

Next time the user want to start a program, the following message appears: “This program is blocked by group policy. For more information, contact your system administrator.”

Blocked By Group Policy

5. Disallow File Removal

This disallows normal file removal. We are going to change the security setting so no one even the administrator can erase files.

Remember, you are the boss, so everyone has to know it.

Right click over the file and select properties. Go to Security Tab.

Click on Advanced, Change Permissions. Uncheck “Include inheritable permissions from this object’s parent”. If a Window appears select Remove, and press Ok. The following message appears: “You have denied all users access to <name of the file>. No one will be able to <name of the file> and only the owner will be able to change the permissions. Do you want to continue ?”

Windows Security Message

Press Yes.

If you enter Windows will ask to change the permissions.

Windows 7 Indestructible Folder

Just press continue and it will restore access to the user you are now logged. In my example is user, sorry for not being more creative.

Now, right click again over the folder, go to the security tab and select edit. Allow read and deny write for the user. Now an error message will appear when the user try to delete it.

Windows 7 Indestructible Folder Security Tab

Here is a list of names you can use for this file:





Just try to be creative.

    This is not “Computer Fun”. I can only assume that these “devil hacks” were meant to be used at work and on coworkers. BAD IDEA! Who is going to undo the damage – on company time. Do you think that “punishing” people by screwing with their computer – at work OR at home – is “funny”? “Punishing” someone is a childish thing to do and you're going to look pretty damn stupid, sitting there, removing this crap, just before they walk you out the door.

    Please don't post this kind DEVIL SPAM here anymore!!

  2. Angel Luis says:

    Thanks Steve for your comment.

    It's your opinion and is a respectable one.

  3. Steven Downer says:

    Nice things to know. As harmful as they 'can' be in some places. As usual, common sense should be applied when using any of the listed things.

    If common sense is applied, then they can be very harmless and quite fun. Great read! :)

  4. Angel Luis says:

    Thanks for the comment Steven. The idea behind this post is just that, other way to know more about your PC. If you want to do harm there are other ways.

  5. Rich says:

    I completely agree :)

  6. Rich says:

    Fair enough, Steve. Thanks for your feedback.

    All the things are awesome
    Disallow File Removal doesn't works in Win 7
    after the whole process
    it allow the admin to access the Folder

  8. Angel Luis says:

    Thanks Sunil for the feedback.
    You are right Windows 7 ask to change the permissions if you are the admin.
    Let me think and I will update the guide.

  9. Angel Luis says:
