Fix Windows Update Error 0x80240034

There are cases when you encounter some issues while updating your Windows 10 computer. One of these issues is the error 0x80240034. This particular error is a Windows Update Error that appears on the Windows Update pane every time an update fails to install. When this happens, your Windows Update will only get stuck at 1% and nothing happens afterward and eventually fails. If you click on the View Installed Update History, you will see the error code 0x80240034 for the failed updates. You will see this error each time you try to update your Windows PC. Take note that this issue doesn’t only happen to a specific version of the Windows Update but on various different Windows builds based on many users. What’s more, is that some users are also seeing a different error code when their Windows Update fails but they still end up seeing the error code 0x80240034 when they check the Windows Update history. At the time of writing, it isn’t determined yet what really causes this error but it’s most likely due to some corrupted files in the computer which is why the most common solution you can try is resetting the Windows Update cache. On the other hand, other users also resolved the issue by using the ISO and selecting the “Do not keep previous settings” option during the Windows Update so it might be something to do with transferring the previous settings through the update client. For clear instructions in fixing this issue, refer to the two options provided below.

Option 1 – Try to clear the Windows Update Cache/Distribution Folder

As mentioned earlier, a lot of users tried clearing the Windows Update cache to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow the steps below.

Step 1: Tap the Windows key once.
Step 2: Next, type in “command prompt” in the Windows Start Search, and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option from the context menu.
Step 3: After opening Command Prompt, type in “net start wuauserv” and hit Enter.
Step 4: Then type in “rmdir %windir%SoftwareDistribution /S /Q” and hit Enter.
Step 5: Now type in “net start wuauserv” and hit Enter. Once it’s done, try updating your Windows PC again, it should now work just fine.

Option 2 – Update Windows via ISO file

If option 1 didn’t work for you, you can try this second option of updating your Windows 10 computer using an ISO file which means that you will have to create a Windows 10 bootable media and use it to install the latest Windows 10 version. The most user reported that this option works and the reason why it does have something to do with the Windows Update client since the Windows Updates downloaded from the regular Windows Update client seems to create issues such as the error 0x80240034. However, issues like this one don’t occur when the very same Windows Updates are downloaded and installed via an ISO file. Take note that when using a Windows ISO file, you will be asked to choose what you want to do with the previous settings and apps. A lot of users opted for the “Not to keep the old Windows settings” option which has resolved the issue. So if you want to keep the previous settings then you must try to update Windows first while keeping the old settings. However, if it doesn’t work, you have to try installing the latest version of Windows without keeping the previous settings.

Step 1: Click this link and then click the Download Tool Now button.
Step 2: Next, click the “Use the tool to create installation media (USB flash drive, DVD, or ISO file)…” option and follow the next given instructions on the screen.
Step 3: Now select the ISO file option in step 5.
Step 4: After that, you should now have an ISO file.
Step 5: Next, go to the location where you’ve downloaded the ISO file.
Step 6: Then right-click on the Windows 10 ISO file and select the Open with an option and then select File Explorer.
Step 7: Now click on “setup.exe” and follow the next instructions that appear on the screen. When asked, you have to select either: Nothing (clean install) or Keep personal files only option. Take note that you must not select the “Keep personal files, apps, and Windows settings since it doesn’t really work.

Fix CLOCK_WATCHDOG_TIMEOUT in Windows

If you encounter the CLOCK_WATCHDOG_TIMEOUT Blue Screen of Death error while using your Windows 10 computer then it is most likely caused by a specified processor which is not processing interrupts. This occurs when the processor is deadlocked or nonresponsive. Specifically, this kind of Stop error occurs when the processor is having a hard time with the cooperation of its threads and cores. The threads are the tasks performed by cores and some cores can have many threads at the same time. And this is where the problem begins – one thread is waiting for an adequate response from another thread or one kernel is waiting for a response from another kernel and those responses are not coming. In other words, when the processor is unable to continue the processing of tasks since its resources are occupied and are interdependent to get free, such a state is called Deadlock. The CLOCK WATCHDOG TIMEOUT bug check has a value of 0x00000101 which means that an expected clock interrupt on a secondary processor, in a multiprocessor system, was not received within the allocated interval. To troubleshoot the problem, you can check out the possible fixes provided below but before you proceed, make sure that you boot your computer into Safe Mode with Networking only.

Option 1 – Undo or disable overclocking if you have overclocked your system

Go to the Start Menu and open Settings.
Next, select Update and Security and go to the Recover tab.
From there, click on Restart now in Advanced startup. This will restart your computer.
Once you’re in the Advanced startup, go to Troubleshoot and then select the Advanced Options.
From there, select the UEFU Firmware Settings.
Now click on Restart. Once your computer has restarted, it will automatically open BIOS.
From the BIOS, go to the Advanced tab and navigate to Performance and then look for Overclocking.
Once you’ve found Overclocking, make sure that it is disabled. If it’s not, then disable it and then save the changes made by tapping the F10 key.
Start your computer normally and check if the CLOCK_WATCHDOG_TIMEOUT 0x00000101 error is now fixed.

Option 2 – Try running the Memory Diagnostic Tool

The Memory Diagnostic tool in windows can help resolve the CLOCK_WATCHDOG_TIMEOUT 0x00000101 Blue Screen error by checking and automatically fixing any memory-based issues. To run it, refer to these steps:

Tap the Win + R keys to open Run and type mdsched.exe and hit Enter to open the Windows Memory Diagnostic Tool.
After that, it will give two options such as:
- Restart now and check for problems (Recommended)
- Check for problems the next time I start my computer
Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Option 3 – Try to rollback, update or disable drivers

The next thing you can do to fix the CLOCK_WATCHDOG_TIMEOUT 0x00000101 Stop error is to roll back, or update, or disable device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

Open the Devices Manager from the Win X Menu.
Then locate the device drivers and right-click on them to open the Properties.
After that, switch to the Driver tab and click on the Uninstall Device button.
Follow the screen option to completely uninstall it.
Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 4 – Try running the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like CLOCK_WATCHDOG_TIMEOUT 0x00000101. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

Tap the Win + I keys to open the Settings panel.
Then go to Update & Security > Troubleshoot.
From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 5 – Try to disconnect or disable newly installed hardware

In this option, you will have to disable or remove the hardware you’ve just installed recently since external devices could be the one that’s causing the Blue Screen of Death error to appear. To do that, just disconnect any external device that’s connected to your computer physically and then check if it fixes the CLOCK_WATCHDOG_TIMEOUT Blue Screen error.

Option 6 – Troubleshoot the BSOD error in Clean Boot State

You can also troubleshoot the Blue Screen error in a Clean Boot state. There are times when third-party applications cause BSOD errors. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

Log onto your PC as an administrator.
Type in MSConfig in the Start Search to open the System Configuration utility.
From there, go to the General tab and click “Selective startup”.
Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
Next, click the Services tab and select the “Hide All Microsoft Services” check box.
Click Disable all.
Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And to configure Windows to use the usual startup, just simply undo the changes.)
From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Option 7 – Try to update the BIOS

Updating the BIOS can help you fix the CLOCK_WATCHDOG_TIMEOUT BSOD error but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

Tap the Win + R keys to open the Run dialog box.
Next, type “msinfo32” in the field and press Enter to open System Information.
From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
After that, you should see the developer and version of the BIOS installed on your PC.
Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
Now double click on the downloaded file and install the new BIOS version on your computer.
Now restart your computer to apply the changes made.

Fix BlueTooth issues in Windows 10

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.

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.
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.
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.
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.
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.
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.
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.
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.

Increasing Virtual Memory

Hello and welcome to our Increasing Virtual Memory tutorial. Before trying to raise the quantity of virtual memory in your pc system, it's important to get a comprehension of its goal and use. This leads to the constant use of high-performing tasks in addition to keeping multitasking capability. The downside to this process is the fact that relatively, the HDD accesses information slower than a RAM module. Taking into consideration its use in a computer program and how virtual memory works, there isn't any amount of virtual memory allocation. The quantity of virtual memory to be defined for a unique computer program would be determined by the kinds of programs that are started and the quantity of multitasking done. The Microsoft Windows operating system yet does supply a recommended baseline memory based on the number of RAM installed and storage space of the HDD. Virtual memory allocation really indicates the upsurge in how big the paging file is. This file provides the pc program with all the essential instructions on the best way to act once all the installed RAM has been allotted to the running applications. In both Microsoft Windows XP (all variants) and Windows Vista environments, the method to control the paging file size is basically the same. To increase the quantity of virtual memory:

Click on the Start menu and choose the "Control Panel" alternative. When the Control Panel window is started, choose the "Operation and Maintenance" class.
Click on the "System" choice to create the Device Properties Window.
Click the "Advanced" tab and choose the "Settings" button under Operation. In the Operation alternative window, select the "Change" button under the Virtual Memory class.
Choose the hard disk where the Windows operating system is now installed. That can be the same place where in fact the paging file will be saved.
Test on the checkbox for the "Custom Size" to enable you to determine the number of virtual memory you need to use for your device.
Click the "OK" button thrice to shut all of the windows. Click the Start button and restart your machine to enable the upsurge in the number of virtual memory to be finished.

In establishing the number of virtual memory, you'll have to place a maximum value along with an initial. It is suggested that both values be equivalent in order to achieve the finest performance on your pc system.

As the key is selected, in right panel ADSKFLEX_LICENSE_FILE will be visible.
Right click on the key and delete it.

Specify the license server in ADSKFLEX_LICENSE_FILE system variable

Go to Start > Control Panel > System and Security > System.
Select Advanced system settings.
On the System Properties dialog, click Environment Variables.
Under System Variables, click New.
Enter ADSKFLEX_LICENSE_FILE for the variable name and 2080@SERVER_NAME _OR _IP for the variable value.

Note: the license server information most often is recorded in LICPATH.lic file and can be verified there too. ADSKFLEX_LICENSE_FILE system variable supersedes LICPATH.lic. Thus, setting the system variable is preferable when this error is seen.

If the license server is on a VPN or a remote network set the FLEXLM_TIMEOUT environment variable:

Go to Start > Control Panel > System and Security > System.
Select Advanced system settings.
On the System Properties dialog, click Environment Variables.
Under System Variables, click New.
Enter FLEXLM_TIMEOUT for the variable name and 5000000 for the variable value.
Click OK to save the setting.

Note: if needed the variable value can be increased to 10000000.

Mac/Linux:

Specify the Autodesk Network License server information in $HOME/.flexlmrc file.

Use a text editor to create a flexlmrc.txt file and save it in Plain text format (In TextEdit on Mac: Format - Make Plain Text) on desktop. The file content should look like this, except with the name or IP address of the license server.

ADSKFLEX_LICENSE_FILE=@SERVER_NAME _OR _IP

If the license server is on the same machine as the Autodesk software, use localhost as the license server name. Thus, the content of flexlmrc file could look like this:

ADSKFLEX_LICENSE_FILE=@localhost

Note: On firewall restricted network or when accessing the license server via VPN, need to include TCP port/s (usually 27000 or 2080) into Autodesk License Server service as follows: ADSKFLEX_LICENSE_FILE=2080@SERVER_NAME _OR _IP

Once flexlmrc file is created move it to user's $HOME folder as follows:

Open a Terminal window
Type open ~ (Mac) or nautilus ~ (Linux) to open $HOME folder
Drag and drop flexlmrc.txt file from Desktop to the home folder.
To make the file a configuration file, rename it to .flexlmrc (please note . [DOT] in front of the file name) by running the following command:

mv flexlmrc.txt .flexlmrc (Mac)
mv flexlmrc .flexlmrc (Linux)

Verify that the license server information registered with the product is correct (versions 2020 and later only)

In versions 2020 and later, the license server information is registered with the AdskLicensing service running locally on the workstation. When changing to a new license server, the old server information may still be registered with AdskLicensing and result in the error above, if this is not appropriately updated. See the below steps to solve this:

Click the Start menu and type cmd.
Right-click on the Command prompt and choose "Run As Administrator."
In the Command prompt, run the following command, followed by ENTER:

"C:\Program Files (x86)\Common Files\Autodesk Shared\AdskLicensing\Current\helper\AdskLicensingInstHelper.exe" change -pk PRODKEY -pv VER.0.0.F -lm "" -ls "" -lt""

Note:

Replace PRODKEY with the product key correspondent to your product(s). See Look Up Product Keys for the full list.
Replace VER with the version you are using. E.g. 2020 for AutoCAD 2020.
Repeat this step for each software you need to reset.

Open Registry Editor (Start > type regedit > ENTER).
Navigate to HKEY_CURRENT_USER\Software\FLEXlm License Manager.
On the right-side, verify of the ADSKFLEX_LICENSE_FILE key exists. If yes, remove it (right-click > Delete).
Run the software again.
Select Multi-user in the Let's Get Started screen.
Follow the steps to connect to your license server.

How to Fix Low Wi-Fi signal strength on Windows 10

If you are experiencing a Low Wi-Fi signal strength on your Windows 10 PC after you’ve updated or reinstalled it, read on as this post will guide you on what you can do to fix the problem. The way devices connect these days has evolved with our cognitive revolution. Various devices use some or other wireless technology to connect with other devices. However, all wireless technology has some kind of limitation when it comes to range and signal strength. From time to time, you might have faced several Wi-Fi issues. Low Wi-Fi signal strength usually happens after you update or reinstall your Windows 10 system. This issue can be identified easily by looking at the signal bars in the Wi-Fi icon or by measuring its strength. Since this problem is wide scope, there are tons of possibilities which is why this post covers the most generic situations that could help most users. Refer to the options given below to fix the low Wi-Fi signal strength of your Windows 10 PC.

Option 1 – Try running the Network Adapter Troubleshooter

If a few days ago the range and signal of the Wi-Fi was perfectly fine before you did an update or reinstall, it is possible that there were some changes made in the configuration as well. In most cases, the latest configuration that came with the update has not aligned the config in your computer or laptop. The easiest and simplest way to fix this is by using the Network Adapter Troubleshooter. How? Follow the steps below.

Right-click on the Wi-Fi icon from the system tray to start troubleshooting.
After that, select Troubleshoot problems. Note that it might take a while to run it but once it’s finished, it will show you all the problems with the network adapter.

Note: The Network Adapter Troubleshooter will also fix the issues in the background but there might be some issues that will require manual action. And if the troubleshooter wasn’t able to identify and fix the problem for you, proceed to the next given option below.

Option 2 – Try using the Device Manager

If the problem is related to hardware, you need to seek out the help of the Device Manager. To do so, follow the steps below.

Pull up the Device Manager.
Next, look for your Wi-Fi adapter under the Network Adapters.
Once you found it, right-click on it and open Properties.
After that, you will see all the actions related to drivers under the driver tab.
You can either update or roll back the selected driver or you could also disable and re-enable it to see if the problem’s fixed.

Note: If updating the driver didn’t help, you might have to dig into the advanced settings. From this post on, it can get a bit complicated as there are terms that you might not understand as well as some configuration. To make it easier for you, you can search for your Wi-Fi adapter online and try following the instructions from there. And before you make any further changes to your computer’s settings, make sure that you create a system restore point first.

Option 3 – Try changing the Wi-Fi Roaming Sensitivity

If you want to enhance the Wi-Fi reception as well as the performance on your Windows 10 PC, you might want to change the Wi-Fi Roaming Sensitivity or Aggressiveness. Roaming Sensitivity is the rate at which your computer chooses and switches to the nearest available point of access which offers a better signal. It is based on the strength and quality of the Wi-Fi and not on the distance to the Wi-Fi point.

Option 4 – Try adjusting the Wi-Fi range

The issue could also be caused by the position of your computer with respect to the Wi-Fi router instead of your hardware or drivers. It could be that your physical location might be a factor for the low signal strength of your Wi-Fi so you might want to adjust the Wi-Fi range to fix the problem.
