Printer not activated, error code 30

Error Code 40 – What is it?

Error Code 40 is a device driver error that users encounter on any Windows 2000 and later operating systems. It occurs when the peripheral device that you connect to your PC cannot be accessed due to a change in the system registry.

This is due to the presence of invalid sub-keys of the device driver in the system registry. It is a common error that users come across and appears on your PC with either of the following messages:

“Information in the registry entry for this driver is invalid”

OR

"Windows cannot access this hardware because its service key information in the registry is missing or recorded incorrectly. (Code 40)"

Solution

Error Causes

As mentioned above, the error code is triggered when the device driver’s invalid sub-keys appear in the registry, effectively changing it. This happens when the windows system files get damaged due to the following factors:

• An incomplete program uninstallation
• An incomplete program installation
• Hardware is not removed properly
• System recovery from viruses
• An improper system shut down

Factors such as incomplete installations or uninstallations or an improper system shut down can cause files to become damaged that threaten the health of your computer.

Removing viruses from the computer is also another factor as it removes the entries in the Windows system files which contain the viruses including spyware or malware

Further Information and Manual Repair

Fixing Error Code 40 is similar to fixing other device manager error codes. Here are a few methods you can try.

Method 1 – Use System Restore

You can use system restore to eliminate the problem. Here is how you can use it:

• Log in using an Administrator account
• Click ‘Start’ button and select All Programs > Accessories > System Tools > System Restore
• Click ‘Restore my computer to an earlier time’ and click ‘Next’
• Select the last Windows restore point from the ‘On this list, click a restore point’ list, and click ‘Next’
• Click ‘Next’ on the confirmation window to proceed
• Restart your PC after restoration is complete

By restoring the system via a last saved system checkpoint, you can obtain undamaged Windows system registry files that can help avert the error code.

Method 2 – Manually uninstall then reinstall the device driver

If using system restore also does not work in removing the error code, you may have to resort to manually uninstalling and then reinstalling the device driver causing the problem.

This would be necessary since the remaining incomplete files due to a partial removal or installation of programs is what contributes to the error code. By uninstall and reinstalling the device driver program, it would lead to the completion of the files.

You can do this by firstly logging in as Administrator and open Device Manager. Select the device that is causing the problem and double click it and make sure that the peripheral is connected properly to the PC. Upon opening, click on the ‘Driver’ tab and then select ‘Update Driver’.

Make sure to refer to the system documentation that you received with your PC or computer to check for the motherboard details and driver specifics.

Method 3 – Use software to automatically download the driver

Manually uninstalling and reinstalling the driver will do the trick, however, it may be time-consuming especially when you would have to resort to your hardware user manual.

Therefore, using a program such as DriverFIX can save you a lot of time and frustration in having your device work properly on your computer.

DriverFIX, with its user-friendly approach to help you fix your PC issues, comes with an integrated database that detects which drivers you need to reconfigure within just a few seconds and downloads it automatically.

It further ensures that your drivers are installed in their entirety leaving no room for any incomplete files to remain that create Error Code 40.

It also has the added advantage of being able to backup and restores your files should there be the slightest possibility of system file damage.

Thus, registry damage can be averted by letting the software roll back the system files to an earlier healthy checkpoint. Driver Assist is the answer to fixing your PC error codes accurately and quickly.

Click Change and make sure the slider is set to On. This will broadly mean that the mic is now enabled on your PC. Next, make sure the slider under Allow apps to access your microphone is set to On, then look through the list of Microsoft Store apps to make sure the apps you want to use are selected. You’re likely to be using many apps, not from the Microsoft Store, so to make sure these are enabled, scroll down even further and set the Allow desktop apps … slider to On.

Check Microphone Driver

The outdated or corrupted driver could be the issue for the microphone not working in Windows 10. To check the driver status, follow these steps:

1. In your Start menu search for Device Manager
2. In the device manager window search for sound and expand it.
3. Once expanded, you should see your audio drivers. Note that the names of these will vary depending on the manufacturer.
4. On Audio, right-click, and select properties. On the General tab, check to see if the device is working properly.
5. If it is not working properly, click on the driver tab and select the update option.
6. Repeat for the other audio drivers.
7. Restart the computer.

Check the Sounds setting

1. In the taskbar, right-click on the speaker icon at the far-right corner and select the sound option.
2. On the Recording tab, click on the microphone and select the Properties option.
3. Select the levels tabs and increase the volume for both microphone and microphone boost.
4. Go to the Enhancement tab of the same pop-up and make sure that the immediate mode checkbox is checked.
5. Click Ok and restart the computer.

The sound troubleshooter

1. Right-click on the sound icon at the far-right corner of the taskbar and select troubleshoot sound problems.
2. The computer will detect any fault that exists with your audio and recommend fixes for you. You just need to read through the prompts and click the options that you think will work for you.

Try microphone on another computer

If previous steps have not produced results, try the microphone on another computer, if it is not working there then it is a hardware malfunction

The third time is charm saying goes but not when we are talking about Microsoft. Print spooler is again in focus, in a bad way. This is the third print spooler vulnerability to emerge in just five weeks. While a critical flaw was originally identified and patched in June, a similar flaw came to light shortly after and was subsequently patched (with mixed success). Microsoft is once again advising its customers to disable Windows print spooler after a new vulnerability that allows hackers to execute malicious code on machines has emerged. While a patch fixing the flaw will be released in due course, the most effective workaround currently on the table is to stop and disable the print spooler service entirely.

"An elevation of privilege vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights."

Stop this service right away or you are risking a potential attack.

1. Press ⊞ WINDOWS + X to open the hidden menu
2. Click on Power Shell (admin)
3. In Power Shell type in the following command to check if spool service is running: Get-Service -Name Spooler followed by ENTER
4. If spooler service is running type in the next command to stop it: Stop-Service -Name Spooler –Force and press ENTER
5. Then follow with this command to disable it at startup: Set-Service -Name Spooler -StartupType Disabled followed with ENTER

That’s it, we hope a patch will come soon for all the people that are using network printing and indeed need this service running in order to do work.

A surprisingly large amount of things present at your home can and do interfere with your wi-fi signal making it weak so devices are dropping it, having trouble connecting, or being slow.

Hello and welcome to our latest article where we will take a look at all things that are present in a lot of homes but are very bad for your WI-Fi signal.

Bad router placement

Having a router in a bad position can have some really large effects on WI-Fi signal strength and its availability. Usually, we do not give great attention to where we are placing our router but it has been proved over and over again that being close to certain objects does indeed have a great influence on the wireless signal strength and performance.

So, what are these objects and bad positions where we could place the router and effectively kill his Wi-Fi capabilities?

Fish Tanks

Water will block all radio waves including Wi-FI signals and waves themselves, so having a router next to the aquarium or any large source of water is a bad idea. You should always look at water as something bad for your Wi-Fi and move your router away from it as far as possible.

Bookshelves

Paper is another story and example of the dampening effect on radio waves. Did you know that various patterns of paper are used in silent rooms and recording studios in order to eliminate sound reflection from surfaces? Well besides absorbing sound waves, the paper also absorbs Wi-Fi signals and if you have a large bookshelf with a lot of books packed one beside another you just have a great wall of signal absorbing.

Mirrors

The problem with mirrors is in their coating that goes over the glass in order to turn it into the mirror, that coating is metal and as such, it is absorbing signals in large amounts. If you have an old or high-quality mirror that has a silver coating things are even worse since silver will absorb even more waves than modern cheap ones.

TV

Yup, TV is also on this list and for a similar reason as a mirror, although TV does not have coatings of metal, they have something even worse: a large metal plating on the back. Metal plating is there to produce structural integrity of the TV set and provide it with shielding from electromagnetic waves and as such it will prevent Wi-Fi waves as well. Do not place the router behind your TV.

Things that influence signals in homes

Any kind of metal decoration

Now when we covered mirrors and TV because of the metal they have, we must take a look at the metal itself. Any kind of metal stuff that you might have like baskets, figures, statues, frames, etc will effectively block your signal.

Kitchen appliances and Home utilities

Kitchen appliances like refrigerators, microwaves, ovens, stoves, etc. along with home appliances and utilities like dishwashers, washing machines, dryers, etc are large metal objects enclosed in a metal cage that will block signals from spreading further and it is no secret that most kitchens have weaker Wi-Fi because of this reason.

Home gyms

This is a logical conclusion as to everything explained so far if you have a workout room or small gym at home it is probably filled with weights that are metal and have mirrors inside, all of that will interfere and block signals.

Things blocking your Wi-Fi that you have no easy control over

Walls

Thick walls will dampen signals, thick walls from bricks will dampen even more and concrete walls will kill it almost completely. Any kind of metal reinforcement wiring inside walls will reduce and kill signals as well.

Floors and ceiling

This is somewhat important if you have a floor beneath or under the room where is your router located, but for the same reason how walls are blocking your signal floor and ceiling can do it as well, especially since most of the time they are made of some stronger material like concrete with metal fence inside.

Heating systems

If you have a heating system that is composed of metal radiators with water inside, then in terms of Wi-Fi signal strength you have an aquarium but in a metal box, and as such it will greatly reduce signal strength.
