Windows can’t find one of the files in theme

Fatal error C0000034 happens during the installation of the Windows update and if you are one of the unlucky users who sadly run into this, keep reading as we will provide solutions to this error and how to get around it. Start from point 1 to the bottom and hopefully you will have your PC back into working order in no time.

1. Run Windows Update troubleshooter

   Usually, a built-in Windows troubleshooter can solve issues painlessly and fast, my advice is to try this as the first option, it is a simple and clean solution worth trying and in 90% it solves the issue all by itself.

2. Do a clean boot

   Using task manager, remove all nonessential applications and services from starting up, reboot your computer, and once it is cleanly booted try re-running the update process again, if the issue was running the application this time everything will work since the problematic application is not running.

3. Reset Windows update components to the default

   This solution requires you to use the Reset Windows Update Agent Tool to reset Windows Update components to default or use this PowerShell script to reset Windows Update Client. You can also manually reset each Windows Update component to default and then re-run the update.

4. Disable firewall and antivirus

   Altho not likely it is still a possibility that some firewalls and antivirus can detect windows updates as malicious software and cut them off. If everything else failed, disable the firewall and your PC protection and when it is fully disabled try updating.

5. Do automatic startup repair

   This should be the last thing to do but if everything else failed, do it. Perform Windows 10 Startup Repair. Once the startup repair completes successfully, you can re-run the update. The update should install without errors.

If you receive an error message saying, “Windows Update cannot currently check for updates because updates on this computer are controlled”, while trying to change the Windows Update preferences or manually update, then read on as this post will guide you in fixing it. You can mostly encounter this error in managed systems where an Administrator controls the permission on the operating system. The reason why you are not able to modify the Windows Update preferences or manually update your system is that a group policy prevents you from doing so and that the only user who can do these things is none other than the administrator of the system. Troubleshooting this kind of problem is the same as when you troubleshoot an error message that says, “Some settings are managed by your organization”. In such cases, you need to check both the Windows Update Group Policy and Registry settings. If you’re just a standard user, you have to contact your system administrator regarding this issue and if you are the administrator, you can make adjustments to the system settings via the Registry Editor and the Group Policy Editor. Refer to the instructions given below for detailed instructions.

Option 1 – via the Registry Editor

If you are using the Home edition of Windows 10 and you want to change the policy for non-admin users on your local computer, then you can use the Registry Editor for that. Here’s how you can do it:

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to the following registry key:

HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows

• From there, look for the key named “WindowsUpdate” in the Windows folder and if it does not exist, you can just right-click on the Windows folder and select New > Key.
• Now name the new key “WindowsUpdate” and create a new sub-key under the newly created key and input “AU” as its name.
• Keep AU selected and then right-click anywhere in the right pane and select New > DWORD (32-bit) Value.
• Then name the Value as “AUOptions” and right-click on AUOptions and select Modify.
• Next, change the value of the Value data to “5” and click OK to save the changes made to the settings. Note that the Value Data of 5 refers to the policy to allow the local admin to choose the setting.
• Now restart your computer once you’re done and check if non-admin users can now modify the Windows Update settings or update Windows.

Option 2 – via Group Policy Editor

• Tap the Win + R keys to open the Run dialog box and then type “gpedit.msc” and hit Enter to open the Group Policy Editor.
• Next, navigate to this folder: Computer Configuration > Administrative Templates > Windows Components > Windows Update.
• Now look for the “Configure Automatic Updates” policy on the right pane and double click on it to open its Properties.
• After that, shift the Radio button to “Enabled” and from the drop-down menu for Configure automatic updating, select option 5: Allow local admin to choose the setting.
• Then click on Apply and OK to save the changes made to the settings.
• Restart your computer and check if the problem’s fixed or not.

The Local Security Authority Subsystem Service or LSASS.exe is a process in the Windows operating system that is valuable as it enforces the security policy on the computer. Every time you log in to the Windows Server, the LSASS.exe is the one that handles the password changes and creates the access tokens while updating the security log. However, it is also frequently targeted by malware and is often imitated. The original location of this file is at “C:/Windows/System32” so if you open the Task Manager and notice that a process with a similar name has a different location then it is definitely a threat and is exploiting the security of your computer. To resolve issues related to LSASS.exe, here are some fixes that could help.

Option 1 – Use the Performance Monitor’s Active Directory Data Collector

Note that this option will only work on the recent Windows server versions. Refer to the steps below to use the Performance Monitor’s Active Directory Data Collector set on your computer.

• Tap the WINKEY + R button to open the Run dialog box.
• Then type “Perfmon.msc” in the field and hit Enter to open the Performance Monitor and from there open the Server Manager.
• Next, navigate to Diagnostics > Reliability and Performance > Data Collector Sets > System from the left side of the navigation bar.
• Then right-click on “Active Directory Diagnostics” and select Start from the context menu. This will take about 5 minutes or 300 seconds depending on the performance capabilities of your hardware to gather the data required and then take some more time to compile a report from the gathered data. Note that these timings are dependent on one another.
• After the report is compiled, you can find it under Diagnostics > Reliability and Performance > Reports > System > Active Directory Diagnostics. The report will contain all the information as well as conclusions. However, it does not mean that it will also contain the exact cause of the problem with LSASS.exe. Nevertheless, it should help you in fixing the problem.

Option 2 – Try to run the System File Checker

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be the cause why the LSASS.exe file is having some issues. To run the SFC command, follow the steps given below.

• Type “cmd” in the Start search and then right-click on the appropriate search result.
• Next, select “Run as administrator” to open Command Prompt with admin privileges.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

 Now restart your computer and see if the problem is fixed or not.

Option 3 – Put your computer in a Clean Boot State

If none of the options given above helped, you can try putting your computer in a Clean Boot State as this can help you in finding any incompatible programs that’s causing the problem.

• 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.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Once you’ve found any incompatible programs, you need to uninstall them. Refer to the steps below to do so.

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the concerned program and select it and then uninstall it.

Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it.

Option 2 – Try to delete the file using Command Prompt

On the other hand, if you were trying to delete the file instead of renaming it, you can execute another command in Command Prompt.

• Open Command Prompt with admin privileges like what you did earlier.
• Once you’ve opened Command Prompt, copy and paste the command given below and tap Entre after you do so. You also have to make sure that you key in the correct path where the file is located as well as its name.

rd /s \?X:badfolderpath

Note: In the command above, “X” is the placeholder letter so you must input the letter that corresponds to the drive’s letter where the file is located.

• After that, you will see the “Operation completed successfully” message on your screen. If you don’t, check if you’ve really inputted the correct location of the file or its name.

Option 3 – Delete the file without any extension

If the file you were trying to delete does not have an extension, this means that Windows does not know what to do with this file which is why it’s throwing an error message. The best thing to do in such cases is to delete the file especially if it takes up a lot of memory. To delete these kinds of files, here’s what you have to do:

• Follow the first two steps from the previous option above so you can navigate to the location of the file accurately just be careful in inputting the folders.
• Don’t forget to tap Enter right after each command and then use the next command below so you can delete the affected file which has no extension:

Building a custom PC is a great feeling but it can sometimes not be ideal and we are not talking about breaking or losing parts. What we mean is that choosing the right components can be sometimes a difficult task. Of course, picking a PC case can have its issues, choosing the right power supply can be tricky but pairing all components together, especially CPU and GPU can be tricky. Builders with no depth knowledge and experience can sometimes choose improper CPU or GPU, picking one of them to be much more powerful than another thus not using it to its full potential because another component cannot handle stuff at the same speed. In order to not be trumped by this kind of stuff, there is a website that is completely free and you do not even need to be registered in order to use it. Bottlenet calculator link here What is even better, once you input your components you will get advice on what to change in order to tweak the system a little more to avoid bottlenecks even more. It is a very useful tool and we are advising you to use it in order to save money but not throwing it on some component that will be half used.
