[FIX] Windows 10 Shows No Users On Login Screen

Today, in this post, we’re going to discuss a very annoying issue in which a Windows 10 user gets locked out on his machine. Imagine, you started your Windows 10 and on the login screen, there is no user listed. In this case the login screen is blank and there is no account being displayed which you can select and enter its credentials to sign-in.

Here is the typical login screen you’ll see in this case:

We recently came across this issue on a Windows 10 Pro running machine. This is one of the worst case we’ve seen in which Windows 10 user is completely locked out. If you’re also victim of this problem, and you don’t want to Refresh or Reset Windows 10, this post may help you.

Here are few things you can try to recover your Windows 10 in such a case:

FIX: Windows 10 Shows No Users On Login Screen

Though you can use System Restore to fix this issue, but in case if you don’t have restore points created, you can restore System Image backup. In case if you can’t follow any of these recovery options, here is something to do:

FIX 1 – Using Registry

Registry Disclaimer: The further steps will involve registry manipulation. Making mistakes while manipulating registry could affect your system adversely. So be careful while editing registry entries.

1. Plug in the bootable Windows 10 USB and boot in Advanced System Recovery Options, select Command Prompt.

4. Finally, set the Value data to 0 from 1. Click OK and close Registry Editor, Command Prompt and Continue to your operating system. This will reboot the machine itself and after restart, you’ll be able to sign-in to your account.

If the issue still persists, try FIX 2.

FIX 2 – Via Command Prompt

1. Follow step 1 of FIX 1.

2. In the Command Prompt window, type following command and press Enter key:

net user administrator /active:yes

3. Use the Settings app to access the Recovery options

To get into Safe Mode in Windows 10, you can also use the Recovery options available from the Settings app. Open Settings (Windows + I) and head to the Update & security section.

Windows 10, Safe Mode, boot, recovery, repair

On the left side of the Settings window, press Recovery.

Windows 10, Safe Mode, boot, recovery, repair

On the right side of the app, in the Advanced startup section, click or tap on the Restart now button.

Windows 10, Safe Mode, boot, recovery, repair

After Windows 10 restarts, you’ll have to follow the same steps as those we’ve shown you in the second method from this guide. In short, you must go to “Troubleshoot -> Advanced options -> Startup Settings -> Restart”. Then, press 4 or F4 on your keyboard to start in Safe Mode, press 5 or F5 to boot into “Safe Mode with Networking,” or press 6 or F6 to go into “Safe Mode with Command Prompt.”

4. Boot from a recovery drive

In Windows 10 you can use the Recovery Drive app to create a system recovery USB drive. Once you have created a USB recovery drive, use it to boot your Windows 10 device and, when you're asked to load its content, do so.

Windows 10, Safe Mode, boot, recovery, repair

The first screen asks you to choose the layout for your keyboard. Select the one you want to use, or if you don't see it listed, press on “See more keyboard layouts” to get the complete list of available layouts.

The next steps you need to take to boot into Safe Mode are the same ones we showed in the second method from this guide, which is to follow this path: “Troubleshoot -> Advanced options -> Startup Settings -> Restart.” Then, press the 4 or the F4 key on your keyboard boot into minimal Safe Mode, press 5 or F5 to boot into “Safe Mode with Networking,” or press 6 or F6 to go into “Safe Mode with Command Prompt.”

5. Use a Windows 10 installation drive and the Command Prompt

If you have a Windows 10 installation DVD or USB memory stick lying around, or if you can create one right now, you can use it to boot your broken PC with Windows 10 into Safe Mode. To create a Windows 10 installation drive, follow the steps from this tutorial: How to download Windows 10 Creators Update and create your own installation media. Then use it to boot your broken Windows 10 PC from it and wait for the installation environment to load. Choose the language and keyboard layout you prefer and click or tap on Next.

Windows 10, Safe Mode, boot, recovery, repair

Next, click or tap on the link that says “Repair your computer” on the bottom left corner of the screen.

After a moment, Command Prompt tells you that “The operation [was] completed successfully.”

Windows 10, Safe Mode, boot, recovery, repair

Then close the Command Prompt and choose to Continue on the next screen.

Windows 10, Safe Mode, boot, recovery, repair

After your PC reboots, Windows 10 will automatically boot into Safe Mode.

6. Interrupt the normal boot process of your Windows 10 PC

If Windows 10 fails to boot normally three times over, the fourth time it enters by default in an Automatic Repair mode. Using this mode, you can boot into Safe Mode. To trigger the Automatic Repair mode, you must interrupt the normal boot process three consecutive times: use the reset or the power button on your Windows 10 PC to stop it during boot, before it finishes loading Windows 10. If you use the power button, you might have to keep it pressed for at least 4 seconds to force the power off. When your Windows 10 PC enters the Automatic Repair mode, the first thing you see is a screen that tells you that the operating system is “Preparing Automatic Repair.”

Windows 10, Safe Mode, boot, recovery, repair

Wait for Windows 10 to try to make an automatic diagnosis of your PC.

Windows 10, Safe Mode, boot, recovery, repair

Then, on the “Automatic Repair” screen, press the “Advanced options” button.

Windows 10, Safe Mode, boot, recovery, repair

On the next screen, choose Troubleshoot.

Windows 10, Safe Mode, boot, recovery, repair

From here on, the steps you’ll have to make are the same as those we’ve shown in the second method from this guide. Follow the path “Troubleshoot -> Advanced options -> Startup Settings -> Restart.” Then, press the 4 or the F4 key on your keyboard boot into minimal Safe Mode, press 5 or F5 to boot into “Safe Mode with Networking,” or press 6 or F6 to go into “Safe Mode with Command Prompt.”

7. Use F8 or Shift + F8 (doesn't work when using UEFI BIOS & SSDs)

In Windows 7, you were able to press F8 just before Windows got loaded, to open the Advanced Boot Options window, where you could choose to start Windows 7 in Safe Mode.

Some websites advise you to press Shift+F8, just before Windows 10 starts loading so that you make it launch the recovery mode, from where you can boot into Safe Mode. The problem is that most times, Shift+F8 and F8 doesn't work, even though they are correct commands, supported by Windows 10.

This official blog post from Microsoft (Designing for PCs that boot faster than ever before) explains that this behavior is caused by their work in creating a very fast boot procedure. Both Windows 8.1 and Windows 10 have the fastest boot times ever. To quote Steve Sinofsky:

“Windows 8 has a problem – it really can boot up too quickly. So quickly, in fact, that there is no longer time for anything to interrupt boot. When you turn on a Windows 8 PC, there's no longer long enough to detect keystrokes like F2 or F8, much less time to read a message such as “Press F2 for Setup.” For the first time in decades, you will no longer be able to interrupt boot and tell your PC to do anything different than what it was already expecting to do.”

If you have modern PC with a UEFI BIOS and a fast SSD drive, there's no way you can interrupt the boot procedure with your keypresses. On older PCs, with a classic BIOS and no SSD drive, pressing these keys might still work though.

Conclusion

Windows 10 is a fast operating system with a fast boot process. Getting into Safe Mode might not work the way it did in older Windows operating systems, but the methods available are similar to the ones in Windows 8.1. If you happen to know of other ways to do this, don't hesitate to let us know and we promise we’ll update this guide.

Can I Remove a Virus Without Antivirus Software?

Jessica Drew
Can you remove a virus without anti-virus software? The short answer is yes, but it's not easy. Sometimes, depending on how nasty the virus is, you'd need to be a computer genius to successfully remove a virus manually. However, if you are somewhat technically savvy, you can try few things before opting for anti-virus software protection.

Why is it so Hard to Remove a Virus Without Software?

A hacker, or sometimes a team of hackers, who create computer malware all have at least one goal in common. That is to make it as difficult as possible to remove a virus they create from your computer. Some hackers are very intelligent and spend countless hours brainstorming ways to hide corrupt files all throughout your computer, making removal extremely difficult. In general, you cannot simply use Windows Add/Remove software tool to get rid of most viruses today. The display icons for the virus may disappear, but the virus will still be running, hidden in the background on your computer, and continuing to wreak havoc on your system.

In order to remove a virus without software, you will most likely need to search online and download a long list of instructions. You will need to know your computer inside and out and have a good chunk of time to dedicate to the manual removal of a virus. However, if the virus that ails your computer is not all that malicious by relative comparison, a few generalized quick steps, listed below, may or may not do the trick.

Some Quick Steps to Try to Remove a Virus

Hold down the CTRL, ALT and DEL buttons simultaneously – this will launch the Windows Task Manager. Once the Task Manager launched, click on the Processes tab. Look through every single process, which is a program that is currently processing information on your computer. If you see anything that looks unfamiliar, search the file name on the web and see if it's connected with any viruses. If you're confident that a particular file is corrupt, click the End Process button for this file.
Launch your System Configuration utility and click the Startup tab. This lists all the programs that automatically run once your computer is booted. Most viruses launch themselves whenever you load up your OS, so again, look for any odd or unknown programs on this list. If you see a program with a surefire red flag, delete it from this list.
Click the Start>Computer menu and go to your hard drive utility. Delete the viral files directly from your hard drive. This may or may not delete the virus in its entirety.
Remove a Virus Easily With Software

If you have a very nasty virus, removing it manually is going to consume a lot of your time. If you are not particularly tech savvy, trying to remove a virus manually could be a waste of time if you're not successful, and it will give you a headache in the process.

The top-rated anti-virus software suites have a high rate of success when it comes to removing many types of pre-existing infections on your computer. The best anti-virus software can also protect you from nearly 100 percent of future threats. Since this software ranges in price from as little as $30 to $60, many users find that using anti-virus software to remove a virus is by far the best solution.

1. De quoi est composée votre batterie de téléphone portable ?

Les premières batteries de téléphones portables étaient composées de Nickel Cadmium. Cette technologie avait ses avantages mais également ses inconvénients, dont une décharge rapide.

Puis le phénomène de miniaturisation des téléphones portables est apparu. Les batteries ont dû prendre le pli. Elles doivent maintenant pouvoir fournir assez d’énergie pour faire fonctionner plusieurs éléments, dont les écrans qui possèdent de plus en plus de couleurs, en plus d’autres éléments, tels que les appareils photos, le lecteur mp3… Tout cela dans un espace de plus en plus petit.

En conséquence, depuis les années 90, les batteries de téléphone portable au Lithium sont de plus en plus répandues. L’un des avantages de cette technologie est qu’elle est capable de stocker beaucoup d’énergie dans un minimum d’espace.

2. Nos conseils d’utilisation incontournables

Pour ne pas user prématurément votre batterie de téléphone portable, nous avons listé pour vous quelques astuces. Nos conseils sont issus de notre expertise de plus de 30 ans ainsi que des échanges que nous avons avec nos clients, professionnels comme particuliers.

Nous vous recommandons de ne pas laisser votre téléphone portable branché sur le chargeur quand sa batterie est chargée.
Avant sa première utilisation, il est nécessaire d’effectuer une recharge complète de la batterie de votre Smartphone ou de votre Iphone. De même, lorsqu’elle n’est pas utilisée pendant une période prolongée, une batterie pleine se décharge progressivement et doit être rechargée avant utilisation.
Nous avons également remarqué qu’une grande partie des clients se présentant avec une batterie défectueuse, charge constamment celle-ci pour la maintenir à 100%. Il vaut mieux attendre que la batterie soit déchargée à moins de 50% pour la remettre en charge.
Comme la plupart des produits composés d’éléments électriques et de circuits électroniques, les batteries n’aiment pas les températures extrêmes. Il faut éviter d’exposer votre batterie à des températures trop excessives surtout lors de la charge. L’idéale est de placer votre batterie dans un lieu frais et bien ventilée, loin de la lumière directe du soleil.
Préservez la durée de vie de votre batterie : ne la laissez pas en charge pendant plus d’une semaine. Une surcharge risque de réduire sa durée de vie.
Les batteries ont un cycle de vie. Si la durée de la charge de votre batterie diminue considérablement, cela signifie que votre batterie atteint la fin de sa vie utile. Nous vous conseillons alors de remplacer votre batterie par une batterie du même modèle.
