Windows activation or validation fails with error code 0x8004FE33

Symptoms

Windows activation or validation fails when you try to activate Windows operating systems over the Internet.

Additionally, you may receive one or more of the following errors:

Error code: 0x80004005 Description: License Activation (SLUI.exe) failed.

Error code: 0x8004FE33 Description: Acquisition of Secure Processor Certificate failed.

The activation failure does not prompt you for credentials.

These problems may occur when you connect to the Internet through a proxy server on which Basic authentication is enabled.

Note: If the proxy server is configured for Basic authentication, the server requires that you type a username and a password. However, the activation user interface does not let you enter these credentials. Therefore, the Basic authentication fails, and activation fails.

If you experience other errors than those mentioned above when you try to activate Windows, go to the following Windows websites for additional troubleshooting information:

Workaround

Method 1: Activate Windows by telephone

Use the Windows Activation Wizard to activate Windows through the automated telephone system. To do this, follow these steps for your version of the operating system.

Swipe in from the right edge of the screen, and then tap Search. Or, if you are using a mouse, point to the lower-right corner of the screen, and then click Search.

Type SLUI 04, and then tap or click the displayed icon to open the wizard.

Click Start, and then click Run.

Type SLUI 04, and then click OK to open the wizard.

Method 2: Configure the proxy server to disable Basic authentication Configure the proxy server to disable Basic authentication. For information about how to use this method, see the documentation that is included with the proxy software.

Method 3: Configure the proxy server to exclude URLs for certificate revocation lists Configure the proxy server to exclude the URLs for the certificate revocation lists (CRLs) from the requirements for Basic authentication. To do this, configure the following list of CRLs to be unauthenticated on the proxy server:

For information about how to use this method, see the documentation that is included with the proxy software.

Note Microsoft cannot supply IP addresses or ranges of the servers listed above. The URL must be used.

Control. Causes Validation Свойство

Определение

Возвращает или задает значение, указывающее, вызывает ли элемент управления выполнение проверки для всех элементов управления, требующих проверки, при получении фокуса. Gets or sets a value indicating whether the control causes validation to be performed on any controls that require validation when it receives focus.

Значение свойства

Значение true , если элемент управления вызывает выполнение проверки в любом элементе управления, требующем проверки при получении фокуса; в противном случае — значение false . true if the control causes validation to be performed on any controls requiring validation when it receives focus; otherwise, false . Значение по умолчанию — true . The default is true .

Примеры

В следующем примере кода используется производный класс TextBox и проверяется адрес электронной почты, который вводит пользователь. The following code example uses the derived class TextBox and validates an email address that the user enters. Если адрес электронной почты имеет формат, отличный от стандартного (содержащий » @» and » .»), проверка завершается неудачно, ErrorProvider отображается значок, и событие отменяется. If the email address is not in the standard format (containing «@» and «.»), the validation fails, an ErrorProvider icon is displayed, and the event is canceled. Для одной из кнопок формы CausesValidation свойство имеет значение false . One of the buttons on the form has its CausesValidation property set to false . Если щелкнуть или установить фокус на эту кнопку, проверка не будет активирована. Clicking or setting focus to this button does not trigger validation. Для этого примера требуется TextBox , чтобы в ErrorProvider форме были созданы элементы, элемент управления и Button . This example requires that a TextBox, an ErrorProvider control, and a Button have been created on a form.

Комментарии

Если CausesValidation свойство имеет значение false , Validating Validated события и подавляются. If the CausesValidation property is set to false , the Validating and Validated events are suppressed.

CausesValidationЗначение свойства обычно устанавливается в false для таких элементов управления, как кнопка справки. The CausesValidation property value is typically set to false for controls such as a Help button.

About Genuine Windows

Support for Windows 7 ended on January 14, 2020

We recommend you move to a Windows 10 PC to continue to receive security updates from Microsoft.

Genuine versions of Windows are published by Microsoft, properly licensed, and supported by Microsoft or a trusted partner. You’ll need a genuine version of Windows to access the optional updates and downloads that help you get the most from your PC.

To learn how to activate Windows, see Activate Windows 7 or Windows 8.1. If you’re using Windows 10, see Activation in Windows 10.

Here are answers to some common questions about genuine Windows software.

Look for key features of genuine Windows software, such as the Certificate of Authenticity (COA), a proof of license label, and an edge-to-edge hologram. For more information, visit the What to look for page on the Microsoft How to Tell website. Your safest option is always to buy Windows from Microsoft, or to buy a PC with Windows preinstalled directly from Microsoft or a store you know and trust.

If you’re seeing these notifications, it’s likely that your copy of Windows wasn’t properly activated. Click the notification and follow the steps to repair Windows or buy a genuine version of Windows if you find out the software is counterfeit.

Until you correct the issue, you’ll receive periodic reminders that Windows is not genuine. Your desktop may also turn black to emphasize the messages. You can reset it, but it will return to black every 60 minutes until the issue is resolved.

Windows will always be able to get critical security updates, even if your version isn’t genuine. However, other updates and benefits are available exclusively for genuine Windows software.

Activation helps verify that your copy of Windows is used only on PCs that the Microsoft Software License Terms allow. It pairs your product key or digital entitlement with your hardware configuration. Usually, you only need to activate Windows once, unless you make a significant hardware change.

When your PC downloads updates, Windows checks to see if your product key or digital entitlement is valid. If it is, you’re eligible to receive the latest updates from Microsoft. If it’s not, your PC is running non-genuine Windows.

You can’t install Windows on more PCs than the Microsoft Software License Terms allow. Usually, a copy of Windows can only be installed on one PC. To learn more about licensing Windows on more than one PC, go to the Microsoft Volume Licensing website.

Yes. You’ll still be able to get critical security updates. However, many updates are exclusively for customers with genuine versions of Windows. We strongly recommend that you get genuine Microsoft software immediately to keep you safer while using your PC.

Validation is an online process. It verifies that your copy of Windows is genuine and that critical Windows licensing files haven’t been damaged, deleted, or removed. It takes only a few moments and lets Microsoft create a match between your PC’s hardware profile and your 25-character product key or digital entitlement.

Your copy of Windows may need to be validated before you can get downloads and the updates which are reserved for PCs that are running genuine Windows. Windows might also prompt you to run genuine validation if activation isn’t properly completed.

If your copy of Windows fails validation, you’ll see a results page that tells you why it isn’t genuine. You’ll also see info about how to resolve the issue.

There are a few common scenarios in which Windows running on a PC might be discovered to be non-genuine during validation.

Repairs. If your PC has been repaired, you might start to see messages on your desktop that Windows isn’t genuine. If the repairs required Windows to be reinstalled, the technician may have activated Windows with a different key than you used when it was originally installed. You might not see the messages until you try to download something from the Microsoft Download Center that requires validation, and validation fails. To fix the issue, you can properly activate Windows by reentering your original product key.

For other issues, you may need to buy a genuine version of Windows.

1 License = 1 PC. Another common cause of Windows validation failure happens when you try to install Windows on more PCs than your license allows. For instance, if you purchased a copy of Windows and installed it on more than one PC, online validation might fail because the product key has already been used on another PC. The rule for most copies of Windows is that only one copy of Windows can be installed on one PC. To learn about licensing more than one PC, go to the Microsoft Volume Licensing website.

Counterfeit software. Validation will also fail if you’ve inadvertently acquired and installed counterfeit Windows software. The Microsoft How to Tell website can help you identify counterfeit software and file a counterfeit software report if needed. Validation failure is common for versions of Windows that were purchased from an online auction site, or if Windows was on a used PC that you purchased. Remember to ask the seller for the Certificate of Authenticity and the original Windows disc, if there was one.

To file a counterfeit report, go to the Microsoft How to Tell website.

You can file an online report if you inadvertently bought or received counterfeit software, or have information about a person, business, or online site that might be selling counterfeit software. The report you submit will be treated as confidential. Microsoft devotes substantial time and energy to fighting software counterfeiting, and you can be assured that we will take appropriate action in response to your report.

If you got an error when you were activating Windows, you can find what it means. For details, go to Get help with activation errors.

You’ll need a product key when you install Windows. To learn more, go to Find a product key.

The validation fails when you run a cluster validation wizard for a Windows Server 2008 cluster

This article provides a resolution for a problem in which a duplicate address error occurs when you validate a Windows Server 2008 failover cluster.

This article contains information about how to modify the registry. Make sure that you back up the registry before you modify it. Make sure that you know how to restore the registry if a problem occurs. For more information about how to back up, restore, and modify the registry, click the following article number to view the article in the Microsoft Knowledge Base: 322756 How to back up and restore the registry in Windows

Original product version: В Windows Server 2012 R2
Original KB number: В 969256

Symptoms

When you run a cluster validation wizard for a Windows Server 2008 cluster, the validation fails. Additionally, you may receive an error that resembles the following error message:

Verifying that there are no duplicate IP addresses between any pair of nodes.

Found duplicate physical address 02-10-18-39-6D-38 on node servername.domainname.com adapter Local Area Connection 19 and node server2name.domainname.com adapter Local Area Connection 19.

Found duplicate IP address fe80::100:7f:fffe%14 on node servername.domainname.com adapter Local Area Connection 11 and node server2name.domainname.com adapter Local Area Connection 11.»

Cause

This problem occurs when only one of the following conditions is true:

• The Teredo transition technology is enabled on a Windows Server 2008 cluster node. Teredo allows IPv6 communications to pass through IPv4 NATs and IPv4 servers. However, Teredo gives the same IPv6 address to its network interfaces. Failover clustering flags this as an error because it requires unique IP addresses.
• The referenced servers are built from the same image and automatically create the Cluster NetFT adapter on each node with an identical MAC address. Failover clustering flags this as an error because it requires unique physical addresses.

Resolution

There are two possible solutions, depending on the combination of error messages that you receive.

Issue 1

If the error message doesn’t include a reference to a «duplicate physical address,» Teredo is most likely the cause of the problem. To resolve this problem, disable Teredo by using one of the following two methods.

The failover cluster validation tests have been changed in Windows Server 2008 SP2 and later and Windows Server 2008 R2 so that the Teredo addresses will not cause the test to issue a failure or a warning.

Method 1: Turn off Teredo by using a Netsh command

Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

If the User Account Control dialog box appears, confirm that the action that the dialog box displays is what you want, and then click Continue.

At the command prompt, type the following lines (press ENTER after each line):

Close the command prompt.

Method 2: Turn off Teredo by specifying a registry setting in Windows Server 2008

This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base: 322756 How to back up and restore the registry in Windows

For best results, close all programs on the computer on which you’re changing the registry setting.

Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

If the User Account Control dialog box appears, confirm that the action that the dialog box displays is what you want, and then click Continue.

Type regedit at the command line.

Locate to the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6

Right-click Parameters, click New, click DWORD, and then type the name DisabledComponents for the new value. Make sure that you type the name exactly as shown, including capitalization. Then, click Enter.

Double-click DisabledComponents.

In the Edit DWORD Value dialog box, click Hexadecimal under the Base field, and then type 8 in the Value data field.

Click OK.

Restart the computer.

You can also disable Teredo by using Device Manager. However, this only disables the Teredo adapter so that the system does not show the adapter anymore. This does not disable the underlying logic for Teredo. This could cause issues later. Therefore, we recommend that you disable Teredo through the command line or through the registry entry.

Issue 2

If the error message includes a reference to a «duplicate physical address,» the problem most likely occurs because the referenced servers are based from the same image. To resolve this issue, remove and then reinstall the Failover Cluster feature. To do this, follow these steps:

Remove the Failover Cluster feature. To do this, follow these steps:

1. Open Server Manager.
2. In the navigation pane, click Features, and then click Remove Features.
3. Click to clear the Failover Clustering check box.
4. Review the warning dialog box to make sure that you’re prepared to continue. Click Yes, and then click Next.
5. Verify that the options that you want are being removed, click Remove, and then click Close.

Reinstall the Failover Cluster feature. To do this, follow these steps:

1. Open Server Manager.
2. In the navigation pane, click Features, and then click Add Features.
3. Click to select the Failover Clustering check box, and then click Next.
4. Verify that the options that you want are being added, click Install, and then Close.

The Sysprep command is not supported when an image is captured after you add the Failover Clustering feature. If you install the Failover Clustering feature, and then you run the sysprep command on the image, the virtual adapter for all the nodes will have the same MAC address. The virtual network adapter (NetFT) takes a MAC address based from one of the addresses of the physical network interface cards (NICs) when the Failover Clustering feature is installed.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the «Applies to» section of this article.
