Cleaning the registry after uninstalling programs

Today, in this article we will look at how to clean registry from " traces"remote programs.
For example, after deleting the 360 ​​application Total Security There are several keys left in the registry, for example, HKEY_LOCAL_MACHINE/SOFTWARE/360 Total Security and folders with files like C:Users/username/AppData/Local/360 Total Security, where the value Username corresponds your account name. As can be seen from the names of the remaining registry keys and folders, the search should be carried out not just by name applications, but also by company name, which developed program.

This is done manually like this...

After uninstalling the program in a standard way you should search for the remaining file folders through means search. Typically there are several certain directories in which folders and files can be located various programs (you need to view objects containing both the name of the program and the name developer):

C:Program Files;C:Program Files/Common Files;

C:Users/username/Application Data;

C:Users/username/Local Settings;

C:WindowsTemp.

By default some of the listed folders are hidden. To access them you should

temporarily allow display hidden and system objects.

Temporarily - because,after completing the procedure for removing unnecessary objects

Parameter hiding system objects recommended reactivate.

It will be safer this way.

1. Open any folder on your computer.

2. Press the key Alt on the keyboard to display the menu bar in the folder window.

3 . Select menu command Service →Folder properties(Folders settings).

A dialog box of the same name will open.

4. Go to the tab View. The contents of the dialog box will change.

On the tab View dialog box Folder properties You can change additional settings for displaying folder contents.

5. In the control group Extra options scroll the slider vertical stripe scrolling down to display the items you want.

6. Reset the checkbox Hide protected system files (recommended).

A warning dialog box appears.

7 . Click the button Yes to confirm the action.

8. Set the switch to position : Show hidden files, folders and drives

9. Click the button OK. Dialog window Folder properties will close and

hidden and systemic objects will be displayed.

After clean your computer, set the controls described above to position default

Cleaning the registry

Manually cleaning the registry - requires patience and attention. For example, when searching for a registry key by a certain value search stops at the first found match

What we are looking for. To continue the search you should select the appropriate command menu Edit--Find Next or F3. Now, I'll show you how to work with registry editor, included in operating system Windows XP.

1 . Click the button Start, located on the taskbar.

2. IN line search located at the bottom of the main menu, enter the value

regedit.

3. Click the button OK. A program window will open Registry Editor

4. Select menu command Edit → Find.

A dialog box will open Search.

As in the case of searching for folders and files left behind when deleting an application, so

When searching for keys in the registry should use titles both the application and the developer. Since we are removing the “tails” of the application360 Total Security then..

5. In the input field Find-- specify value 360 Total Security

and press the button Find next.

Window Search will close and the search process will begin.

When you find the desired key or partition-- make sure what are you going to do

Delete data related to the remote application.

You can delete a key or partition two ways.

In one case, the value is highlighted by clicking the mouse and pressing a key -Delete on the keyboard. Otherwise, you can click on the value right click mice and in the appeared context menu select item-Delete.

In both cases, you will need to confirm your intention by pressing the button Yes,

In the dialog box that appears.

Typically, programs place data in sections SOFTWARE

standard sections

HKEY_CURRENT_USER(current account settings),

HKEY_LOCAL_MACHINE(parameters of this computer)

You should be very careful when making changes to the registry. Incorrect actions when

Changing the registry can seriously harm the system. Before making changes to the registry

preferably create backup copy registry

Continue with your steps to clear the registry of the remaining keys:

1. After deleting the found registry key - continue search by pressing a key F3.

2. Repeat the registry search with keyword360 Total until it appears

"registry search completed" window

As you can see, the process manual cleaning "traces" remote programs is a very tedious task and you need to be patient, and most importantly, attention.

Don't forget to periodically clean the registry, especially after uninstalling programs. I recommend program Wise Registry Cleaner cleans well, and most importantly, safely and optimizes the registry system on the tab of the same name.

Hello everyone, today we will look at an interesting topic, namely deleting a key from Windows registry 10, I mean your Windows activation key. It is stored in the registry in encrypted form, but the fact is that it is not so difficult to decrypt and, of course, look at it. Do you understand? An attacker could take advantage of this!

So it may even be useful to remove it from the registry, since it can be used during the activation of other systems, as a result, your key will be blocked, you will not be able to use updates, and in general your Windows will become UNlicensed.

But this does not apply to MAC keys, they are not stored in the system, and also if your system was activated using a KMS server, because it uses a GVLK key, but everyone else needs to take care of their key, you have it in any case must be saved somewhere.

This method is suitable not only for the new Window 10, but also for other systems, that is, for seven, eight and even whist

I’ll tell you right away that you shouldn’t worry, this is all safe and will in no way change your current activation, everything is as it was - so it will remain. This key is already a dead weight; the system does not access it at all in the future. But I hope that somewhere you even have a key to your system? Well, maybe it’s stuck on the laptop or on the box

Now let's get down to business - let's open it command line with administrator rights, to do this, press Win + X and select this item:

A black window appears, this is good, now you need to check that the system has been activated and everything is fine, enter the following command:

We press enter and see this message:

Now you can delete the key using this command:

In response, the team returned a message that the product key was successfully removed from the registry. The system remained the same as it was activated. But, there is something else interesting, even if you deleted the key, then using this command: slmgr /dlv you can get the last five characters of the key!

In the article, we looked at how you can add an entry to the Windows registry via the command line or via a bat file. There is a reverse command that allows you to remove keys from the Windows registry, called Reg Delete. Let's look at the syntax of this command.

In general, the Reg Delete command looks like this:

reg delete section_name

Let's look at the syntax in more detail:

section_name— indicates the section in which the required registry keys are located. In fact, the path to these keys. If the path contains spaces between characters, it must be enclosed in quotes.

For example, in the screenshot below we see that registry variables related to the 7-Zip program are located in the branch HKEY_LOCAL_MACHINE\SOFTWARE\7-Zip.

/v entry_name— the name of the registry key to be deleted. If you do not specify, all subsections and keys will be deleted.

/ve— delete nameless parameters.

/va— request all parameters of this section.

/f— delete forcibly without additional warning.

If the operation needs to be performed on remote computer, then before the partition name you need to add the computer name like this \\computer_name\partition_name. Further command syntax remains unchanged.

Example of using the Reg Delete command:

reg delete \\Test-PC\HKEY_LOCAL_MACHINE\SOFTWARE\TEST /v ABC

This command will remove the parameter ABC In chapter HKEY_LOCAL_MACHINE\SOFTWARE\TEST on the computer Test-PC. If deletion occurs on local computer, then it's enough

reg delete HKEY_LOCAL_MACHINE\SOFTWARE\TEST /v ABC

If we need to delete the entire partition TEST entirely, then you can use the command

reg delete HKEY_LOCAL_MACHINE\SOFTWARE\TEST

As you can see, the Reg Delete command is not difficult to use. However, you need to be careful, since thoughtlessly deleting registry keys and keys can have a negative impact on the operating system and the software in it.

Hello admin! Question, how to clean the registry from accumulated garbage: remaining keys, parameters, values remote programs, but I want to do it correctly, since I have a sad experience.

Just recently I installed one program on my computer and was surprised to find that another one was installed along with it, some kind of operating system and registry cleaner. The most interesting thing is that this program began to run along with Windows, constantly offering to clean the computer of various garbage. Just for fun, I decided to try it and clicked OK, the process of cleaning the registry from unnecessary entries began, after a minute the check ended and the program issued a report, 1024 errors were found, which the utility offered to fix, I agreed and clicked OK again, the registry errors were deleted and the computer rebooted and didn't boot anymore!

The next time I booted, the error Windows\system32\config\system... and something else appeared on a black screen. With great difficulty, we managed to restore the operating system using your article.

I also found an interesting article on your website where you can clean the registry of keys left behind by a virus without resorting to any programs. That's why I decided to write to you and ask how to clean the registry from garbage, and is it even necessary, because many users never clean the registry at all and don’t think about it.

How to clean the registry

1) What is a registry!

2) Is cleaning the registry really necessary?

3) Did you know that if a malicious program leaves its keys in the registry, then no registry cleaner will find them. How to find unnecessary keys in the registry manually without resorting to any programs.

3) How to clean the registry with EnhanceMySe7en

4) How to clean the registry with CCleaner

Hello friends! A good question has been asked and to answer it, I will tell you in a nutshell what the registry is and how it is used by Windows.

The register is the most important Windows component, appeared in ancient Windows 3.1 as a file Req.dat.

The registry contains a huge database or repository of configuration information of all programs installed on the operating system and Windows itself. Information about all users, file extensions, drivers, connected devices, activations, and so on, all this is stored in the registry.

Any application, when installed in the operating system, leaves its configuration data in the registry, and also any application does not delete all data from the registry when it is uninstalled (removed) from the computer. This is a well-known fact.

For example, I will remove a program from my computer Adobe Photoshop, and then I’ll check the registry for the presence of keys for this program and they will be there,

The same thing will happen with the Download Master program.

And if you remove a more serious program from Windows, for example, then pay attention to how much garbage it leaves behind in the registry. And if you imagine that we have been using the operating system for a year!

It becomes clear that quite a lot of this junk left by programs after being removed from the computer remains in the registry, but here’s another question, my friends - does all this junk interfere with the performance of the operating system? No one has been able to prove what is preventing it. Isn’t this proof that the well-known Microsoft developer of Windows himself never created a special tool for his brainchild that would automatically clean the registry. yes, it is also present, but you can clean the registry only manually using the special regedit editor built into Windows.

In what cases do I clean the registry myself?

Friends, at one time I experimented ad nauseum with various registry cleaners, but never came to a convincing result. I believe that there is no great need for constant automatic cleaning registry, since no automatic cleaning is as good as you think. If you deleted a program and it left its keys in the registry, then Windows will never access these keys and because of these keys there will in no way be a drop in system performance or any errors. Garbage in the registry can amount to several tens of kilobytes of unnecessary sections and have no noticeable impact on system speed

But how to delete unnecessary entries in the registry you should still know and here's why.

As an example, I will give a real case. A friend of mine picked up a malicious program that launched an executable file from the C:\Windows\AppPatch\hsgpxjt.exe folder. We successfully removed the virus, but created in the registry malware the records remained because when the system booted, this window appeared.

None of the existing automatic registry cleaners helped me then; they simply did not find malicious entries.

I had to manually find malicious keys in the registry located in the registry hives

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Windows

Keys added

Load REG_SZ C:\WINDOWS\apppatch\hsgpxjt.exe

Run REG_SZ C:\WINDOWS\apppatch\hsgpxjt.exe

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

Key added

userinit REG_SZ C:\Windows\apppatch\hsgpxjt.exe

I wrote a detailed article about this case "" you can read it. From this article you can learn how to find unnecessary keys in the registry using the built-in Windows editor regedit.

Well, what can we wish for users who want to have at hand automatic tool to clean the registry.

How to clean the registry with EnhanceMySe7en

Before using registry cleaner programs, I advise you to create a system restore point (let’s lay down a straw before we fall)

EnhanceMySe7en also contains a startup manager, hard defragmenter disk drive, hard drive monitoring tool, and process manager (some tools are only available in paid version). This cool program is unfortunately not English language, but everything will be clear to you anyway.

Official website of the program http://seriousbit.com/tweak_windows_7/

To start cleaning the registry you need to go to the Tools tab and click just one button Registry Cleaner.

Then you can view the Details or directly click on Delete button Remove errors.

That's it, the registry is cleared.

How to clean the registry with CCleaner

Answer Yes

Windows 10 stores the product key in the registry. You may have heard and perhaps used some applications that allow you to search for your key Windows product 10. These applications use information stored in the registry to find and display the product key. If you ever need to, you can remove the product key from the registry.

Cautions:

Deleting a key will not affect your current activation status, but that doesn't mean you should delete it just for kicks.

Under normal circumstances, there is no need to remove the product key from the registry. If your system is working fine, you don't need to update one Windows version 10 to another, you haven't changed any major hardware, etc., you don't need to remove the key. More importantly, if your actual key is not recognized as valid, deleting it is not a solution. The easiest way to resolve the activation issue is to simply call Microsoft (or download the activation program).

If you decide that you need to delete your product key, make a backup copy first. This is especially important if you have a retail or OEM key, or if you upgraded from Windows 7 or 8/8.1 to Windows 10.

Finally, if you have any problem that requires you to remove a product key from the registry, first try using your system with a local account Windows recording 10 to see if the problem persists.

Remove product key

To remove a product key from Windows 10, you will need administrator rights.

Open a command prompt with administrator rights. Enter the following command. For the second time, click " Enter", the key will be deleted. If you have any thoughts, do not press Enter until you have dealt with the hazard.

slmgr-cpky

Once you press Enter, the product key will disappear and all applications that can read it will no longer be able to find it. You must reboot the system after running the command for the changes to take effect.

Change product key

If you need to change your product key, there is a certain settings, and you don't have to manually delete the old one. To change your product key, open the app " Settings" and go to " Update and Security" Go to the " Activation" Scroll down and click Change Product Key.
