Configure Windows 10 to create Dump Files on Blue Screen of Death

What is Error Code 0xC004C003?

Error code 0xC004C003 has to do with activating Windows 10 after a clean install. This problem has been a frequent nuisance to users trying to update from Windows 7 or 8.1 following the invite path they got from Microsoft.

Solution

Error Causes

There are several problems that may have caused error code 0xC004C003. The most common of them are:

• The product key entered was invalid, and cannot be used to activate the new OS.
• The user followed the proper installation procedure, but the Windows update servers were too busy to handle the activation at that moment.
• The free upgrade invitation was followed but after the reinstallation, the copy of Windows 10 was still not activated.
• The user tried to perform a full clean install of Windows 10 instead of upgrading from Windows to Windows 10

Further Information and Manual Repair

A lot of solving error code 0xC004C003 has to do with the method in which the user has tried to update the system. If one decided to try and update the program before being invited to do so by the update manager, he must wait. Unfortunately, if one chooses to do it on his own and download a clean install, he was never given a product code to authenticate the process. There are two options to address error code 0xC004C003 — either restore to the previous Windows Operating System or call Microsoft (or visit their Website) and purchase a product key. The Windows update servers are very busy. There are lots of Microsoft users around the world, and the servers are doing their best to get to each and every one of the users as fast as possible, but they can only move at a certain speed. Your best bet is to sit back and wait a while. But what if you were invited, and properly downloaded Windows 10, then decided to do a clean install? It is advised that one do not try to enter Windows 7 or 8.1 serial code as this will not work. However, unlike the problem above, these users will NOT need to purchase a product key. According to Microsoft Support Staff, the installation servers are also very jammed because of the high numbers of installations going on right now. No matter what posts you may read, the key IS genuine, and it is NOT blocked, broken, or invalid. To check if Windows has been properly activated, open the Command Window. Make sure you are logged into an administrator profile; otherwise this check will not work. Type in “slmgr.vbs/ato” and click Enter and then wait. While waiting, the command will check on the status of the activation. Windows Script Host will open and show whether or not it is activated. A lot of users have reported that the activation did not work for the first few times. However they later reported after some more attempts, no issue was found in the way the operating system updated and that the activation process went smoothly. This is most likely due to the overload on the Windows Update servers, so bear with Microsoft. Users have reported that when trying to correct error code 0xC004C003, they have followed the upgrade path and then been told by Microsoft that the key was invalid and they had to purchase a new one. If the upgrade path provided by Windows 7 and Windows 8.1 is correctly followed then there is nothing to worry about Just wait a while and try it again. If there are prolonged issues, speak with a technician by visiting the Microsoft website and contacting the help center by calling the number provided. Give them all relevant information and they will be sure to help accordingly. The best solution to fix error code 0xC004C003 is to wait. In essence, the user will be waiting to reenter the same product key. According to Microsoft, and many user posts found online, it is recommended to wait a while and then try to activate again. This seemed to be an answer to most users' problems, and seem to work just fine. If the problem persists, take it to a windows repair technician to have it sorted out. If that does not work, use a powerful automated tool to fix the problem.

If you are trying to log into your user account on your Windows 10 computer but encountered an error message instead that says, “Your account has been disabled, Please see your system administrator”, read on as this post will guide you on how you can fix this problem. In this kind of scenario, you won’t be able to access your data unless you have access to the administrator account. This problem could be caused by several problems. It is possible that malware has infected your computer and has changed some settings in your computer, especially if your system has been under a malware attack not too long ago. The malware could’ve changed the “Account is disabled” option. The only thing you can do to resolve this kind of problem is to log into your computer using another administrator account and then change the setting. However, if you don’t have a second administrator account, you can just enable the built-in hidden administrator account on your computer. You shouldn’t have any problem enabling the hidden administrator account as it is quite easy when you can log into your account. And in this post, you will be guided on how you can enable the hidden administrator account using the Registry Editor to fix the “Your account has been disabled, Please see your system administrator” error.

To get started, follow the instructions given below.

1. First, you need to start your computer and ensure that you are on the error screen. From there, you will see the Power options located on the right-hand side.
2. Click on the Power options and tap and hold the Shift key and then select Restart.
3. After that, the Advanced Boot Options will appear and from there select Troubleshoot > Command Prompt.
4. Next, you have to select your user account and enter the user account’s password to open Command Prompt.
5. After opening Command Prompt, open your screen and type “Regedit” and then tap Enter on your keyboard.
6. Now select the HKEY_LOCAL_MACHINE in the Registry Editor and go to File > Load Hive.
7. Afterward, you have to open the Windows installation drive and go to the location – WindowsSystem32Config
8. From there, you should find a file named “SAM” – select this file and click the Open button.
9. Next, you have to enter a key name. You can just input whatever you prefer.
10. Once done, navigate to this path: HKEY_LOCAL_MACHINEkey_nameSAMDomainsAccountUsers
11. From this path, you will see a key named “000001F4” – select this key and double click on the “F” entry that you can find on the right-hand side of the screen.
12. After that, look for the value data line labeled “0038” which should show 11 in the first column. You have to replace it with 10.
13. Once done, click on the OK button and close the Registry Editor and the Command Prompt to restart your computer.
14. Now once your computer has restarted, sign in to the Administrator account and open the Computer Management window. You can just search for it using the search bar in the Taskbar.
15. After you open Computer Management, go to Local Users and Groups > Users – where you can find all the user accounts. Look for your deleted user account and right-click on it and select Properties and then unmark the checkbox that says “Account is disabled”. This should fix the problem.

What Does 0x8007045D Error Code Mean?

The 0x8007045D error code is an I/O (input and output) error that is associated with the registry. It indicates that the Windows operating system has become overloaded with invalid system references in the registry. This may prevent you from executing reading and writing to and from devices successfully.

Error Causes

Registry is the main database of your PC. This portion of your computer saves all the activities that you perform on your PC including the junk files, temporary internet files, invalid entries, bad registry keys, and more. This clutters the hard disk. If the unnecessary files are not removed from the registry, it may lead to I/O errors like 0x8007045D. On the hard drive, some parts of the drive may fail to function. If this is not fixed on the time it may lead to serious disk damage and registry corruption eventually resulting in system failure. System failure can make you lose all the valuable data saved on your system for good.

How to Fix the Error Code 0x8007045D?

Error codes on your PC are like warnings. These codes indicate that your PC has some issue. Therefore ignoring it is not wise. To spare yourself from such serious PC damages, it is advisable to take correct measures timely instead of prolonging and making the situation go from bad to worse.

People are becoming more and more concerned with their privacy and Facebook's flagship messaging application is caught between it all. While still widely popular it has becoming to lose its ground due to many unanswered questions about privacy encryption. Lucky for all of us there are alternatives for more secure messaging.

SIGNAL

Arguably the most secure of all well-regarded messaging apps, Signal is the favorite of the European Commission, as well as newsrooms around the world. While Signal doesn’t disclose how many daily or monthly users the app has, Google’s Play Store says it has been installed more than 50 million times. While using Signal, each voice or video call connected through the app includes full end-to-end encryption. Signal takes an extra step by hiding message metadata so that the location of the original message is missing. While it asks for your mobile number, that number isn’t used with your profile. Instead, it acts as a numeric username. Once registered, you will find 1-1 chat, audio, and video calls, disappearing or “secret” chats, and a privacy lock so nobody can access the app even if they have your phone. Best of all, it’s completely free to use.

TELEGRAM

One of the biggest competitors to Facebook Messenger (and WhatsApp), Telegram is a very strong alternative. With more than 400 million users, it offers an interface that should feel right at home for anyone coming from Messenger. Telegram offers some huge benefits over Messenger, including features like groups that can hold up to 200,000 members for a chat. There is no limit on your media or chat size, and you can share all types of files between users and in groups. From a privacy standpoint, Telegram has robust security, but it is worth noting that only “secret” messages are end-to-end encrypted and can self-destruct. Non-secret messages can be stored on Telegram’s servers so you can pick them up between your devices quickly. That’s a consideration worth knowing prior to making Telegram your default Messenger replacement. Telegram is free across all platforms.

THREEMA

Rising in popularity, Threema is another privacy-focused alternative that has quickly become a competitor to Facebook Messenger. This paid service ($2.99 on both App Store and Play Store) is a pay-once, use forever option. Once you pay the small fee, you gain all of Threema’s touted privacy options, like open-source end-to-end encryption for both messages and calls. Like Signal, Threema won’t require you to link any phone numbers or emails to your account. All chats are handled anonymously, and the service generates a random user ID when you first open and register for the app. No data is collected from any of your chats and no ads are shown. The Swiss-made app does have its own servers hosted in Switzerland, which do not store any chat messages. Another privacy benefit of Threema is the notion that all of your contact lists, groups, and user profiles are hosted on your device, not on the Swiss servers. Because of that, Threema can once again state that none of your personal info is stored anywhere they have access.

Bluetooth troubleshooting, I believe firmly that each one of us who has Bluetooth sooner or later had some issues with it, after all, it seems that it is in nature of radio transmitters to from time to time due to nature of signal and nature of Windows loose communication between them and can cause device which seems to work properly but can not establish the connection. Most of the time Bluetooth issues are like that, the signal gets lost, the connection is broken, and establishing it again can be sometimes real pain, luckily for you, we have experience in this field and are here to help you and provide you with tips how to solve Bluetooth connection issues based on our own struggles.

1. Check if BlueTooth is ON

   Yes, this seems stupid and sounds a lot like is it plugged in but here me out. Due to lost connections and different power plans setting inside your Windows, your Bluetooth receiver might be actually turned OFF thus preventing your other device to find your computer. Checking to see if Bluetooth has been by some accident turned OFF and switching it back ON should be the first thing to do and this could be a simple solution for your problem.

2. Restart the BlueTooth device.

   Yup, another of these have you tried turning it OFF and turn it back ON advice which seems like tech cliche but in the case of Bluetooth, this can actually solve your problem. Radio signals and radio connections are not the same kinds of beasts like cable ones and sometimes Bluetooth device remembers certain information and can cause conflict. Turning it OFF and then back ON will clear its memory and cache and you will be ready for a new start hopefully solving your issue along the way.

3. Check power supply

   If your Bluetooth device does not have a battery indicator, it would be wise to check on the battery status of the device. Sometimes we forget to charge batteries, sometimes someones have drained them. Checking the battery or just checking if the power supply is working properly should not be overlooked and it definitely should be on your to-do list of quick solutions.

4. Restart PC

   Sometimes most simple solutions work and if restarting your Bluetooth device did not work, maybe restarting your PC will. When you restart the PC, you clear the cache and many other things that could potentially be the reason for connection issues.

5. Checks BlueTooth device distance from computer or interference from obstacles

   The Bluetooth device operates via radio waves, and like wi-fi, if the distance from the computer is too large or you have some thick walls in between signal will degrade and be almost useless. Be aware that your PC might catch device waves and detect them but the signal itself could be too weak for the connection to work properly. Take the device and move it closer to the PC to see if the problem will go away, if it does issue was in distance or walls.

6. Reinstall or update device drivers.

   Sometimes the issue could be in Windows update and old drivers, make sure that all of your drivers are updated with the latest version and that Windows itself has the most recent update in it. Trying to reinstall device cold also solve some the issue.

7. Remove and Pair deice again

   if you tried all previous steps, try removing the device from Windows and then pairing it again. This could solve the issue since Windows itself could have mistakenly saved it like something else and can not recognize it.

8. Use Windows troubleshooter

   If everything else failed, right-click and go to troubleshoot. Windows troubleshooter will try to find the issue and direct you to a solution.

If sadly none of these things do work, you should contact the device manufacturer since it is a very good chance that the problem is one of a hardware nature.

In today's age of smart gadgets and complete replacement of even some simple things with their smart counterpart, it is not really a surprise to see some strange innovations that try to take advantage of modern technology.

One of these innovations is a smart book, or to be more precise smart note, a reusable notebook that could be connected to your phone.

Why Rocketbook Fusion smartbook

One thing that could justify, well it should justify buying Rocketbook is the preservation of trees and the environment since it can be reused. The second argument would be its price since it is not expensive considering what it offers.

On top of all, you also have a free application for your phone in order to take full advantage of it.

What is a smartbook?

Imagine this scenario, you have a notebook of 42 pages with several different page styles inside. You write in it and after it is filled you upload its content to your email or cloud service of your choice, get a cloth, erase everything and start again from zero.

So as mentioned notebook comes with 42 pages of various page styles. Most of the pages are either lined or dotted but the notebook also includes a monthly calendar, two-week detailed calendar pages, and three pages for project or idea tracking. Since everything can be erased this is enough variety to cover all basis and eliminate any need for another workbook ever.

When you feel like you want to save work or once it is filled you can easily upload and save the workbook from the scan page option in the free Rocketbook app. Once scanned pages can be uploaded to your preferred cloud service or sent to your email.

Now in order to write and be able to erase any of Rocketbook's notebooks, you will have to use Pilot's Frixion writing pens. They will dry around 15s on the page and can be of course easily wiped with a damp microfiber cloth that is included with the purchase. One pen also comes with a workbook when purchased.

Application

Application has cool features, of course, the most important and most useful one is setting your upload scan destination so when you scan your pages they get automatically uploaded to your chosen destination.

In the application settings, you can also toggle some handwriting recognition features that will allow you to easily search your uploaded documents. For example, you can search through documents just by writing now or two words. There is also a Smart List feature as well that will take your checklist and make it into a virtual checklist.

The app also has a fun Explore section where you can find all sorts of fun hacks and different ideas on how to use your Rocketbook.

If you receive an error message saying, “Windows Update cannot currently check for updates because updates on this computer are controlled”, while trying to change the Windows Update preferences or manually update, then read on as this post will guide you in fixing it. You can mostly encounter this error in managed systems where an Administrator controls the permission on the operating system. The reason why you are not able to modify the Windows Update preferences or manually update your system is that a group policy prevents you from doing so and that the only user who can do these things is none other than the administrator of the system. Troubleshooting this kind of problem is the same as when you troubleshoot an error message that says, “Some settings are managed by your organization”. In such cases, you need to check both the Windows Update Group Policy and Registry settings. If you’re just a standard user, you have to contact your system administrator regarding this issue and if you are the administrator, you can make adjustments to the system settings via the Registry Editor and the Group Policy Editor. Refer to the instructions given below for detailed instructions.

Option 1 – via the Registry Editor

If you are using the Home edition of Windows 10 and you want to change the policy for non-admin users on your local computer, then you can use the Registry Editor for that. Here’s how you can do it:

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to the following registry key:

HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows

• From there, look for the key named “WindowsUpdate” in the Windows folder and if it does not exist, you can just right-click on the Windows folder and select New > Key.
• Now name the new key “WindowsUpdate” and create a new sub-key under the newly created key and input “AU” as its name.
• Keep AU selected and then right-click anywhere in the right pane and select New > DWORD (32-bit) Value.
• Then name the Value as “AUOptions” and right-click on AUOptions and select Modify.
• Next, change the value of the Value data to “5” and click OK to save the changes made to the settings. Note that the Value Data of 5 refers to the policy to allow the local admin to choose the setting.
• Now restart your computer once you’re done and check if non-admin users can now modify the Windows Update settings or update Windows.

Option 2 – via Group Policy Editor

• Tap the Win + R keys to open the Run dialog box and then type “gpedit.msc” and hit Enter to open the Group Policy Editor.
• Next, navigate to this folder: Computer Configuration > Administrative Templates > Windows Components > Windows Update.
• Now look for the “Configure Automatic Updates” policy on the right pane and double click on it to open its Properties.
• After that, shift the Radio button to “Enabled” and from the drop-down menu for Configure automatic updating, select option 5: Allow local admin to choose the setting.
• Then click on Apply and OK to save the changes made to the settings.
• Restart your computer and check if the problem’s fixed or not.

If you suddenly find your Windows 10 computer stuck on the “Preparing to configure” screen for quite a long time now after you run Windows Update, read on as you will be guided on how you can fix that issue in this post. During an update process, there’s a lot of things that go on in the background which is why Windows Updates take quite a while before it finishes. It can be at 25%, 50%, or even 100% but the only message you’re going to see on your screen is the “Preparing to configure Windows, Don’t turn off your computer”. However, if you notice that the Windows Update is taking a longer time than it’s supposed to, the first option is to wait some more but if it’s still the same, then there’s definitely something wrong. This kind of issue occurs when Windows Update fails to configure in short correctly download and install the update. When this happens, it will revert all the changes which are why you were advised to wait for a couple of hours. There are two possibilities why your computer is stuck on the “Preparing to configure Windows, Don’t turn off your computer” screen. The first one is that the Windows 10 operating system is installing any updates. The second one is when the user profile takes time to load or encounters an error. There are several options you can try to fix the problem. You can try running System Restore or boot your computer in Safe Mode or repair the corrupted profile via Registry Editor. You might also want to try using installation media to boot and repair your computer if the other options didn’t work.

Option 1 – Perform System Restore

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Note: If you can’t boot into the desktop of your computer, you can run System Restore in the Advanced Startup Options by following these steps:

• Boot your computer into the Advanced Startup Options screen.
• From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
• Now select Troubleshoot > Advanced Options > Command Prompt.
• After that, type “rstrui” and hit Enter to execute the command which will start the System Restore process.
• Once it’s done, restart your computer.

Option 2 – Boot your computer in Safe Mode

You can try to tap the F8 key if you have it enabled in your Windows 10 computer, as you start your system to boot into Safe Mode. Once your computer is in Safe Mode, you can access the Start Menu and the Mouse and Keyboard. Aside from that, you can also access your files and other built-in tools in Windows such as Command Prompt, PowerShell, Computer Manager, Device Manager, Event Log Viewer, and many more. On the other hand, if you haven’t enabled the F8 key, you can just go to the Advanced Startup options to boot your computer into Safe Mode. Once you’re there, select Troubleshoot > Advanced Options > Startup Settings > Restart > Tap the number 4 key. After that, your computer will restart in Safe Mode. If you want to reboot into Safe Mode with Networking instead, you can tap the number 5 key and for Safe Mode with Command Prompt, tap the number 6 key. Once your computer is in Safe Mode, you can use any of the built-in tools to restore your computer or troubleshoot the problem that’s causing your computer to get stuck at the “Preparing to configure” screen.

Option 3 – Try to repair your corrupted profile via Registry

In this third option, you can try to repair the corrupted profile using the Registry but before you proceed, take note that you can only try this if you can boot into your desktop and if you can, make sure to create a System Restore Point and then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter or click OK to open the Registry Editor.
• Next, go to this registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList
• Once you’ve opened the registry key, you should see a list of all the user profiles on your computer. Now click on each S-1-5 folder and look for the “ProfileImagePath” entry and double click on it to check which user account it is related to. You will see a path like “CUsersACK” where “ACK” is the username.
• You should know which of the user account is corrupted. Just look for a key named “RefCount” and change its Value data to “0” and click OK. And if it isn’t available, simply right-click on the right pane and create it.
• After that, double click on the key named “State” and make sure that the Value data is “0” and click OK.
• Exit the Registry Editor and restart your computer to apply the changes made.

Option 4 – Try to use installation media to boot and repair your computer

Another thing you can try to resolve the issue is to use the Windows installation bootable media so you can boot and repair the operating system. To use it, follow these steps:

• You need to first create an installation media which has the dame version of the operating system installed in your computer.
• After that, once you reach the Install Windows screen, click on the “Repair your computer” link.
• Wait until the repair is completed and then shut down your computer
• Now once your computer has restarted, check if it can now boot properly.

If you suddenly get a message telling you that “Your Windows license will expire soon, You need to activate Windows in Settings” on your Windows 10 computer but you know that your Windows 10 is already activated. Worry not for this post will help you get rid of that error message right away. Before you get started, make sure that you have the Windows product key with you. If you don’t, you can get it by running the following command in an elevated Command Prompt:

wmic path SoftwareLicensingService get OA3xOriginalProductKey

Take note of the product key and then proceed to the options given below.

Option 1 – Try activating Windows 10 again or use another product key

• If you’re sure that you have the correct product key, click the Go to the Settings button.
• After that, click the Activate button once again.
• If you have another license key, you can also use that as well, just simply click on the Change product key.
• Then enter the new product key and click on Activate. That should fix the problem, if it doesn’t, refer to the next option below.

Option 2 – Try to reset the licensing status

• Click the Start button and then type “cmd” in the Search box and then tap Ctrl + Shift + Enter to open an elevated Command Prompt.
• Next, type the “slmgr –rearm” and hit Enter to reset the licensing status.
• Restart your computer and check if the error is now gone or not.

Option 3 – Try uninstalling the product key and re-enter it once more.

• The first thing you have to do to uninstall the product key is to know the Activation ID of your Windows installation. To do so, open an elevated Command Prompt and type this command, and hit Enter – vbs /dlv
• After you enter the command, you should see the licensing status and Activation ID. And to get all the Activation IDs of all the installed Windows versions, key in this command and hit Enter – vbs /dlv all

Note: The “/dlv” parameter will give you the license information for the installed operating system.

• After you enter the second command, you should see a Windows Script Host window with all the Windows licensing and activation status. Take note of the Activation ID.
• Next, in the same elevated Command Prompt, type this command – slmgr /upk <Activation ID>

Note: In the third given command, “/upk” stands for “uninstall product key”. This parameter uninstalls the product key of the current Windows edition.

• Restart your PC. After that, your computer will be in an unlicensed state so you need to re-enter the product key again.

Option 4 – Try rebuilding the Tokens.dat file.

The issue might be caused by a corrupted Tokens.dat file. The Tokens.dat file is a digitally signed file that stores most of the Windows Activation files so if it is corrupted then no wonder you’re having activation issues. To rebuild the Tokens.dat file, refer to these steps:

• From the WinX Menu, open an elevated Command Prompt.
• After opening Command Prompt, you need to type each one of the following commands and after you type each command, hit Enter.
  • net stop sppsvc
  • cd %windir%ServiceProfilesLocalServiceAppDataLocalMicrosoftWSLicense
  • ren tokens.dat tokens.bar
  • net start sppsvc
  • exe %windir%system32slmgr.vbs /rilc
• Now restart your computer.

Option 5 – Try running the Windows 10 Activation Troubleshooter

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

Option 6 – Try activating Windows 10 via mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.
