What is DISM Error 1726? Every time you encounter some issues in your Windows 10 computer, especially when it comes to corrupted system files, you can always use the SFC scan and if the SFC can isn’t able to resolve the issue, there is also the DISM tool you can use which usually resolve the vast majority of system file corruption sufficiently. However, there are times when even the DISM commands experience issues as well. Such is the case with the 1726 error: “The remote procedure call failed”.

Some users reported that this DISM problem happens right before the process is supposed to end. According to experts, this error in DISM occurs due to any of the following reasons:

1. A third-party program might have interrupted the DISM operation and is the one that triggered the 1726 error: “The remote procedure call failed”.
2. The error could also pop up when there is a pending corruption repair. This usually happens when you tried to run a DISM command previously that was terminated manually or was halted because of some malfunction.
3. Lastly, the error could also occur because the process that’s responsible for the procedure is disabled or was prevented from running.

Whichever the case is, here are some suggestions that might help you in resolving the 1726 error: “The remote procedure call failed”.

Option 1 – Try updating your PC to the latest Windows build available

Since the problem is specific to certain builds in Windows 10, you need to make sure that your computer is updated before you try other troubleshooting steps. Thus, follow the steps below to update your Windows 10 PC.

• Tap the Win + R keys to open the Run dialog box.
• Then type “ms-settings:windowsupdate” in the field and hit Enter to open the Windows Update screen.
• After that, click on Check for Updates and then follow the next on-screen instructions to apply the latest Windows update.
• Once the update has been installed, restart your PC and run the DISM command again and see if the problem is fixed.

Option 2 – Try to change the Startup Type of the Remote Procedure Call service

As stated early on, the error might also be caused by a disabled Remote Procedure Call service or RPC or that it might be prevented from running for some reason. In case you don’t know, RPC is the service control manager for both COM and DCOM servers and it’s responsible for performing object variation requests, exporting resolution as well as distributing collection for the servers. And so if the server is disabled, all programs that are using COM and DCOM including the DISM commands, will not function correctly. Thus, you need to make sure that the RPC service is scheduled to enable itself on every system boot. To do so, here’s what you have to do:

• Tap the Win + R keys to open the Run dialog box.
• Type “services.msc” in the field and hit Enter to open Services.
• From there, scroll down until you see the Remote Procedure Call (RPC) service and then right-click on it and select Properties.
• Then go to the General tab and change the drop-down menu next to Startup type to Automatic.
• After that, click the Apply button and then OK to apply the changes made.
• Restart your PC and run the DISM command once again at the next startup.

Option 3 – Try to modify the RpcSs registry key value

If the option didn’t work, you can also try enabling the RPC service using the Registry Editor. Before you proceed, make sure to create a System Restore point first and then follow the steps below afterward.

• Tap the Win + R keys to open the Run dialog box.
• Type “Regedit” in the field and hit Enter or click OK to open the Registry Editor. And if a User Account Control prompt appears, just click on Yes.
• After that, navigate to this registry key: HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services RpcSs
• After selecting the aforementioned registry key, go to the right pane and double-click on the Start value.
• Next, change the Value data of start to 2 and click OK to save the changes made.
• Exit the Registry Editor and restart your PC and check if the 1726 error in DISM has already been resolved or not.

Option 4 – Try to disable the Windows Search service temporarily

Some users also recommended disabling the Windows Search service for the meantime as it could be the one that’s interrupting the DISM process.

• Tap the Win + R keys to open the Run dialog box.
• In the field, type “services.msc” to open the Services window again and hit Enter to open it.
• Next, scroll down over the services list and double-click on the Windows Update service.
• Afterward, go to Windows Search properties and click the General tab and then click the Stop button to stop the service from running temporarily.
• Now try running the DISM commands again and see if the problem’s fixed or not.
• Restart the Windows Search service and then restart your PC as well.

A lot of users rely on keyboard shortcuts to carry out tasks on their PCs. One of the most common keyboard shortcuts used is the Ctrl + Shift + Esc which opens the Task Manager. As you can see, the Shift key is not just used to capitalize a text as it can also be used for other functions and plays an essential role in operating a computer. However, if you suddenly find it not working, read on as this post will help you fix the problem. If your Shift key is not working, there are several potential fixes you can check out to fix it. These are the different ways to get rid of the Shift key not working issue on Windows 10:

• 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 the external devices and check if the error is now gone.

Referenced Memory at - What is it?

0x Referenced Memory at 0x is an error code that occurs when the random memory addresses conflict. This error causes running programs or browsers to crash. Referenced memory at error code is considered as a service violation error. It is displayed as the following:

“The instruction at 0xf77041d24 referenced memory at 0×00000000. The memory could not be read.”

Solution

Error Causes

The ‘referenced memory at’ errors is either triggered by:

• Hardware failure
• Problems with the RAM and the registry

Hardware failure may result if the driver is not installed properly. The problems in the RAM indicate registry issues that occur due to data overload in the hard disk and poor PC maintenance. The registry saves all the information and activities you perform on your system on the hard disk. This includes the junk files, temporary files, invalid registry entries, and files of both installed and uninstalled programs.  These files accumulate and take over a lot of RAM space. Also, the referenced memory at error can be considered to be a form of memory leak where unknown third-party software can take up the memory space that has been reserved for a particular program. For example, if you have toolbars and add-ons installed in your browser, it can also lead to invalid registry storage in the registry. If you don’t clean the registry, these unnecessary files can overload your data and lead to hard disk/RAM damage and corruption triggering obscure error messages like referenced memory at error.

Further Information and Manual Repair

Referenced memory is a critical error; if not resolved it can lead to serious PC damages like a system failure. To avoid this, it is advisable to fix it right away. Here are a couple of ways to repair this issue on your system:

Cause: Hardware Failure

Solution: If the referenced memory at error is generated due to hardware failure then to resolve this error you must reinstall the driver that has caused the error to appear. Let’s say if the error pops up because of the printer driver, reinstall it. For re-installation of the driver, simply go to the control panel and click on the Device Manager option. Once you click it you will see a detailed page with a list of devices. Now click on the printer (the problematic driver in this situation) to reinstall the driver software. Double click on it to open the properties dialog box and then click the driver tab and update the driver. Once you have updated the driver, try using the printer. Check if it works. If it works and the referenced memory at the error code does not appear on the screen, this means the problem was with the hardware. However, if the error still pops up then this means the problem is deeper. It’s related to the registry.

Cause: Problems with the RAM and the registry

Solution: If the problem is with the RAM and the registry, then it is advisable to download Restoro. Restoro is a new, next-generation, and highly functional registry cleaner.

There is a built-in tool in Windows 10 the Disk Cleanup Utility which can help you restore hard disk space by removing temporary files, Thumbnails, old Windows files, Windows Upgrade logs, Delivery optimization files, and many more. However, from time to time, this built-in tool also experiences some issues. One of these issues is when it gets stuck on Windows Update Cleanup. Read on to find out what you can do in such a case. When the Disk Cleanup Utility is stuck on the Windows Update Cleanup, the process could be slow and take a long time to complete when purging the files. If this happens, click on Cancel to close the dialog box. After that, try running the Disk Cleanup Tool again as administrator and check if the files that you want to clean is still there or not. If it isn’t there, then this means that the cleanup has been done, otherwise, you need to refer to the options given below.

Option 1 – Try to manually delete the contents in the SoftwareDistribution folder

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

Error Code 0x80070004 on Windows 10 – What Is It?

Some users trying to upgrade from Windows 7 or Windows 8/8.1 reported experiencing installation rollback with error code 0x80070004. This error normally appears when the Computer Name is set to names that can’t be used for the computer. It’s also possible this error occurs if users or program files folder were redirected to a different partition.

Solution

Error Causes

The Error code 0x80070004 on Windows 10 is normally caused if any of the following were used as the Computer Name and the user tried to upgrade to Windows 10:

• System (or SYSTEM)
• SELF
• LOCAL
• Network

Failure to fix this error message might result in others, including error code  0xc0000001. 

Further Information and Manual Repair

If you don’t solve this error, you won’t be able to upgrade from Windows 7 or Windows 8/8.1 to Windows 10. Note that this error will continuously bring you back to the original OS unless fixed.

Please note that if you’re not confident in doing these steps, you might want to consider seeking the help of an expert or using an automated tool that will help fix this.

Here are a few methods to try.

Method 1: Check and Change the Computer Name

The most common cause of this error is if your computer uses any of the following reserved names:

• LOCAL
• System (or SYSTEM)
• Network
• SELF

These reserved names are not meant to be used as computer names. If this is what your computer uses and you try to upgrade to Windows 10, you will surely get this error. Check your computer name and if you see any of the reserved names, change it right away.

Changing Computer Name in Windows 8.1

If you’re trying to upgrade from Windows 8.1, you can change the name of the computer by following these steps:

• Step 1: Open the Start menu then simply type “rename computer”. After that, choose “Rename this computer”
• Step 2: A dialog box will open. Just click the “Change” button
• Step 3: A new dialog box will open. Type the new name. Click Apply then Ok.

Changing Computer Name in Windows 7

If you’re trying to upgrade from Windows, you can follow the steps below to change the name of your computer.

• Step 1: Go to the Start menu then on the Computer section, right-click the mouse and choose “Properties”.
• Step 2: A new dialog box will appear. Go to “Computer name, domain, and workgroup settings” then click “Change settings”. In case you’re asked for administrative access, make sure to grant it.
• Step 3: Find the “Computer Name” tab then click “Change”
• Step 4: Change the computer name and click Ok.

Method 2: Fix the “Users” directory issue

If the first method doesn't work, it probably means the computer name isn’t the cause of this error. Another reason why users experience Error code 0x80070004 when upgrading to Windows 10 is if the “Users” directory was relocated. So, when you try upgrading to Windows 10, the installer wasn’t able to find the user profiles on the “%systemdrive%”, where the current operating system is installed.

If you changed or moved any of the Users, Program Data, or Program Files folders, this will cause the error. Before you upgrade to Windows 10, you might be required to reset or reinstall your current operating system (Windows 7 or Windows 8.1).

If you haven’t made any changes or haven’t moved any of the mentioned folders, there’s a great chance that your users' profiles are corrupted. You can also reinstall your current operating system. However, you might want to check for the corrupter user profile first. To do this, follow the steps below:

• Step 1: Go to the Start menu and type System
• Step 2: Click System  then go to the Advanced tab
• Step 3: Go to Settings, which you’ll find under User Profiles

On the Users Profiles, make a copy of all the accounts somewhere. Sign out from the current user account then try logging in back using the accounts you’ve copied. For each account, you get an error, delete it. However, make sure that you don’t delete the UpdateUser and Administrator account ever.

After this is done, try upgrading your operating system to windows 10 again.

Method 3: Try a trusted and secured Automated Tool

If the above methods still not useful, you might want to rely on an automated tool. Find a secured and trusted tool. It will help fix this issue.
