Compare Exchange128 error – What is it

Some Windows 7 and Windows 8.1 users reported experiencing a Compare Exchange128 error when trying to upgrade to Windows 10. The error reads, “You can’t install Windows 10 because your processor doesn’t support CompareExchange128”. In order to upgrade to Windows 10 (64-bit), the CMPXCHG16B instruction must be present. If you receive this error, this mostly means that your CPU doesn’t have the CMPXCHG16B instruction.

Solution

Error Causes

The CompareExchange128 error normally occurs due to two possible reasons:

• CPU lacks CMPXCHG16b Instruction
• Old & Outdated BIOS – Even if your CPU has the CMPXCHG16b instruction, the CompareExchange128 issue can still occur if you have an older BIOS.

Further Information and Manual Repair

One main requirement to upgrade to Windows 10 is for your CPU to have the CMPXCHG16b instruction. You also need the right BIOS version to guarantee a smooth installation. See below on how to manually fix this issue.

NOTE: If you don’t feel confident using the manual methods listed below, it’s highly advisable to get help from an expert technician. If you don’t know someone, you can also use an automated tool to fix this.

Before performing any fixes, try to determine first if the cause of the error is due to your CPU lacking the CMPXCHG16b instruction. You can use a CPU Info tool that provides complete details about your processor, memory, and motherboard. If you’re looking for more in-depth information, you might also try command-line utilities. But, the safest and easiest way to check this is by simply searching online. Try using the search query: <CPU Model> CMPXCHG16b

Method 1 – Update your BIOS

This method will download the latest BIOS from your motherboard’s manufacturer. This makes sure your CPU has the CMPXCHG16b instruction needed to complete the Windows 10 64-bit installation. To update your computer’s BIOS, complete the following steps:

1. Determine first the current BIOS you have on your computer. Open System Information Windows app and type msinfo32 in the search bar. The BIOS version will appear under the processor speed. Record it somewhere.

2. Go to the support page of your motherboard’s manufacturer. Find if there’s any update on the BIOS that you’re currently using. If you find one, download the BIOS update file available. Make sure that you’re looking into the right model and you download all the necessary documentation. Otherwise, the BIOS update might not work.

3. Update your BIOS. Most BIOS update steps are straightforward. Just make sure to follow the steps provided.

Method 2 – Install Windows 10 32-bit version

If updating the BIOS doesn’t work, what you can do is install a 32-bit version of Windows 10 instead of the 64-bit version. Here’s how to do this:

1. Download and install the 32-bit version of Windows you currently have. If you have a Windows 7 64-bit version, get the 32-bit version of Windows 7. The same goes for Windows 8.1. When you do this, you might want to back up your files first. Remember that installing the 32-bit version works like other installations, and could delete some of your files.

2. After installing the 32-bit version, go to Updates and install all the necessary updates. This includes upgrading to Windows 10 if you’re asked to.

3. When you installed the Windows 10 upgrade, you’ll now have the Windows 10, 32-bit version installed. This will be the version activated on Microsoft servers. Despite this, the activated version stored is only applicable to your computer’s hardware, not the version of Windows 10.

4. Download Windows 10, 64-bit version.

5. Prepare an empty DVD or USB flash drive. Use Creation Media software then click the Create Installation Media for Another PC option.

6. Install the 64-bit Windows 10 version you downloaded from Step 4. Make sure not to put anything when you’re asked to input the serial number.

7. Once the installation is complete, you’ll have the 64-bit version of Windows 10.

Method 3 – Buy a new processor/motherboard

If the above two methods don’t work, there’s a great chance that this error occurs because of an outdated processor/motherboard. Your next possible solution is to buy an updated model that’s fully compatible with 64-bit Windows 10.

Method 4 – Download an automated tool

If all else fails, you might want to consider using this powerful automated tool to quickly fix the problem and any other computer-related issues.

One of the most interesting innovations that were released by Microsoft is the Surface Dial. This only goes to show that Microsoft is very competent not just in hardware but in overall innovation. Although it’s quite a piece of technology and as far as the consensus is concerned, it works pretty well, there are still some issues encountered by users. One of the particular issues experienced by users is that the Surface Dial fails to pair with every Windows 10 PC. At a time of writing, it is still not clear what the cause of the problem really is. However, their possible solutions are provided in this post that might help you resolve the problem. Before you get started troubleshooting the problem, make sure that there are two AAA batteries fitted inside properly.

Option 1 – Check if your PC supports Bluetooth 4.0 LE

In case you don’t know, the Surface Dial only works with the Windows 10 Anniversary Update and later PCs that support Bluetooth 4.0 LE. Thus, you have to check if this is supported or not before you troubleshoot further.

• Tap the Win + R keys on your keyboard to open the Run dialog box.
• Next, type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• From there, click on Bluetooth and select “Microsoft Bluetooth LE Enumerator” from the drop-down menu. However, if it is not there, then it simply means that your computer does not support this standard which is most likely why you were unable to pair with other Windows 10 PCs. On the other hand, if you were able to see it, then proceed to the next troubleshooting steps below.

Option 2 – Check if Bluetooth is on

The next thing you have to do is to check if Bluetooth is turned on. As you know, the Surface Dial connects to your computer using Bluetooth and so you need to check if it’s really on or not. Aside from that, you also have to verify pairing.

• Tap the Win + I keys to open Windows Settings.
• Next, select Devices from the menu and click on Bluetooth.
• After that, make sure that the toggle switch for Bluetooth is turned on.
• Now all you have to do is to verify pairing by pressing and holding the pairing button located beside the batteries and then wait for a few seconds until the Bluetooth light begins to flash.
• Then go back to the Bluetooth section and click on Bluetooth or other devices.
• From there, click on Add Bluetooth and select Surface Dial.
• Follow the next instructions on the screen and click on Done once everything is completed. That should fix the problem.

Option 3 – Check if Surface Dial is connected to another PC

If you think that connecting a Bluetooth device to two different PCs at the same time is wise, then think again as it does not really bode well for the overall user experience. Thus, you need to disconnect the Surface Dial from the system that you are currently using. On the other hand, if everything fails, then it’s most likely that the Bluetooth adapter is the one at fault. So you may have to get a third-party device that connects to your system via USB and then see if it works or not.

One of the most basic and commonly used features in the Windows operating system is the copy and paste feature that helps users accomplish tasks in a faster and easier way. However, if you notice that it’s not working properly for some reason, then this post might be of help as it will provide you with options you can check out to resolve the problem. You can encounter this kind of problem with the copy and paste feature if some system files are corrupted or if there’s some third-party application or process that interferes with this function. Worry not though for there are some options you can check out to fix this. You can try to restart the rdpclip.exe process or the explorer.exe process. You could also try to reinstall the program where you encountered the issue with the Copy and Paste function. In addition, you could try clearing the clipboard history or run the built-in tools like the DISM tool and SFC scan. You could also troubleshoot the problem in a Clean Boot State or use the Refresh Windows tool. For more information, refer to each one of the options below.

Option 1 – Try to restart the rdpclip.exe and the explorer.exe processes

The first thing you can do to resolve the problem is to restart certain processes namely, the rdpclip.exe process and the explorer.exe process via Task Manager.

• First, right-click on your Taskbar and select the Task Manager.
• Next, look for the rdpclip.exe process and right-click on it, and select the End process option.
• After that, click on the File tab > Run new task and then type “rdpclip.exe” and tap Enter.
• This should help fix the problem. If not, you could also try to restart the explorer.exe process – just look for the explorer.exe process in the Task Manager and right-click on it, and then select the Restart option.

Option 2 – Try reinstalling the concerned program

If you only experience this issue on a particular program, you might want to uninstall this program and install it back again, and then see if it fixed the problem or not.

Option 3 – Try to clear the clipboard history

You could also try clearing the clipboard history as it has been known to help in fixing this kind of issue. You can clear the clipboard history using the command line.

• Tap the Win + R keys to launch the Run dialog box and type “cmd” in the field and hit Enter to open Command Prompt.
• Next, execute this command: echo off | clip
• After that, check if the Copy and Paste function is now working properly or not.

Option 4 – Try running the DISM tool

You can run the DISM tool as well to help fix the “Tile Database is corrupt” error. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • DISM.exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.
• Once it’s done, check if it was able to fix the corrupted Start Menu or not.

Option 5 – Try to run System File Checker or SFC scan

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow and hit Enter.
• Once done, restart your computer.

Option 6 – Restart your computer in a Clean Boot State

If a third party program like antivirus is the one that’s causing the problem, you can try to put your computer in a Clean Boot State to isolate the issue by following these steps:

• 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 configure Windows to use the usual startup, just simply undo the changes.)
• Now try to connect your device or copy the files to your external device again and check if the problem with the Copy and Paste function is fixed.

Google Docs has cemented itself as a great free alternative to Microsoft Office Word. Most of the time people just share links to google Docs among themselves but sometimes you need to save and download files.

Luckily Google docs let you download easily files in various formats including PDF as well. In this short tutorial we will explain how can you download your Google document as a PDF file.

Saving Google Docs as a PDF

Open the Google document inside the browser and click on the File drop-down menu. In the file drop-down menu go to Download and choose PDF document. Next, choose the location where you would like your file to be saved and click on SAVE.

And that's all that needs to be done. Also, you can edit PDF files as well in google docs if you need to.

Sometimes, some applications after they are installed will put their shortcut in the context menu (right-click on desktop) for easy access, most of the time these are some system tied applications like AMD and Nvidia control panels or archives like WinRAR or 7ZIP but it can happen even for some usual application to do this.

There are some applications that you use frequently and they could be worth putting in the context menu, if you want to avoid clutter on the desktop or in the taskbar this is the third place that you should consider placing shortcuts.

Doing this will require some playing and tweaking in the Windows registry editor so be careful when editing the registry since bad entries can lead to system crash or instability. Follow step-by-step instructions.

Adding apps to the context menu in the registry

Creating entry

Open the registry editor by searching Regedit and pressing enter than inside of the registry editor search for the next key:

HKEY_CLASSES_ROOT\Directory\Background\shell

Select shell and right-click on it, hover over New and in the submenu click on Key. In the next step, you need to name a key, this name will be the thing that will be shown in the context menu when you right-click on a desktop so type in the name that you would like or the name of the application that you wish to add to the menu.

If you wish you can even add a keyboard shortcut to launch this specific application. To do this select entry that you have created and edit the default value, inside the edit string in the Value data field type first & and after that key that you would like as a shortcut. Now after right click if you hit your shortcut key app will be launched right away.

Adding command

The next task is to create a command key that will actually hold the command to launch the application. Right-click on the entry that you have created, hover over New, and click on Key.

Next, you’ll need to create the command key that will actually hold the command used to launch the application. Right-click on the new Notepad key, and then choose New \ Key from the menu. Name this key 'command', all in lower case and without hyphens.

Now in order to finish setting the launcher, you need the full path of the file that you would like to run. Locate your file in file explorer or in another tool and copy its path by SHIFT + right-clicking on the file itself and choosing copy as path option.

Now click on the command key and double click on the default key on right to edit it, inside the field value data paste your path to executable. close and save the registry and you are done.

If you got an error message saying, “Windows could not start the Windows Update service on Local Computer, Error 87. The parameter is incorrect” while you were trying to start the Windows update service on your computer, then this post could help you resolve the problem. Along with this error, you might also get any of these error codes such as 0x80240034, 0x80244019, 0x80070643, and so on. Aside from these error codes, you will also notice that the Windows Update service has been stopped. To fix this issue, here are a couple of suggestions that might help but before you go on, you need to create a System Restore point first.

Option 1 – Try checking Services Dependencies

Dependencies of a Windows Service in Windows 10 are when windows services depend on other services. Such is the case with the Windows Update service – it also depends on three different services such as the Remote Procedure Call or RPC service, DCOM Server Process Launcher, and the RPC Endpoint Mapper. Meaning to say, if two of these services are not working as expected, then the dependant service will also be affected. This could be the reason why the Windows Update service could not start.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter to open Windows Services.
• From the list of Services, look for the following services:
  • Remote Procedure Call (RPC) Service
  • DCOM Server Process Launcher
  • RPC Endpoint Mapper
• After you find these services, double click on each one of them and check whether the Startup type for all is set to Automatic and the Service status is set to Running or not.
• If the service status is not running, then click the Start button. Afterward, check if you can now run the Windows Update service.

Option 2 – Check the Background Intelligent Service and the Cryptographic Service

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter or click OK to open Services.
• From the list of Services, look for the following services and make sure that their Startup type is as follows:
  • Background Intelligent Transfer Service – Manual
  • Cryptographic Service ­– Automatic
• After that, check if the Service status of the listed services above is set to Running. If they’re not, click on the Start button to start these services and then check if you can now enable the Windows Update service or not.

Option 3 – Reset Windows Update components

If the first two options did not work then you might want to reset the Windows Update components manually. Follow the steps below to reset them.

• Open Command Prompt with admin privileges.
• After that, type each one of the following commands and hit Enter after you key in one after the other.
  • net stop wuauserv
  • net stop cryptsvc
  • net stop bits
  • net stop msiserver

Note: The commands you entered will stop the Windows Update components such as Windows Update service, Cryptographic services, BITS, and MSI Installer.

• After disabling WU components, you need to rename both the SoftwareDistribution and Catroot2 folders. To do that, type each one of the following commands below, and don’t forget to hit Enter after you type one command after the other.
  • ren C:WindowsSoftwareDistribution SoftwareDistribution.old
  • ren C:WindowsSystem32catroot2 Catroot2.old
• Next, restart the services you’ve stopped by entering another series of commands. Don’t forget to hit Enter after you key in one command after the other.
  • net start wuauserv
  • net start cryptsvc
  • net start bits
  • net start msiserver
• Close Command Prompt and reboot your PC.

Option 4 – Run the Windows Update Troubleshooter

If resetting the Windows Update components didn’t work, you could also try running the Windows Update Troubleshooter as it could also help in fixing any issues related to Windows Update including this one. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 5 – Try removing a value from the Windows Registry

If running the Windows Update troubleshooter didn’t help and you receive a message instead saying, “Service Registration is Missing or Corrupt”, you can try to remove a value from the Windows Registry.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Windows Registry.
• Next, navigate to this path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsSelfHostApplicability
• From this path, look for a value named “ThresholdOptedIn” and if you find it, delete it.
• Exit the Registry Editor and see if you can now enable the Windows Update service.
