Windows got stuck on Preparing Windows screen

You might have experienced a situation when you restarted your Windows 10 PC after an upgrade and you tried logging into your account but only a screen with a message saying, “Preparing Windows”. If the screen only stays that way, this indicates that Windows 10 is trying to complete the upgrade or waiting for some files to load up so that you can use your account. Some users also reported that when they tried logging into their accounts, they also get the same message on their screens. To resolve this issue, read on as this post will show you what you can do if your Windows 10 PC is stuck on the “Preparing Windows” screen.

A lot of users have tried logging back into their account once more but to no avail as the same screen still greets them. And even when they tried the Ctrl + Alt + Del combo, it still didn’t work. This only goes to show that your account might somehow be corrupted.

Option 1 – Try booting your PC into Safe Mode

The first thing you can do to resolve the issue is to try booting your computer into Safe Mode and then log in using an Admin account. If it seems like your admin account has caused the problem, you need to create an admin account first and then log in after you reboot into the account and then log off. After that, restart your PC normally and check if the problem’s resolved or not. If not, refer to the next given option below.

Option 2 – Try to repair your corrupted profile via Registry

In this second option, you can try to repair the corrupted profile using the Registry but before you proceed, make sure to create a System Restore Point and then follow the steps below.

  • Tap the Win + R keys to open the Run dialog box.
  • Then type “regedit” in the field and hit Enter or click OK to open the Registry Editor.
  • Next, go to this registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList
  • Once you’ve opened the registry key, you should see a list of all the user profiles on your computer. Now click on each S-1-5 folder and look for the “ProfileImagePath” entry and double-click on it to check which user account it is related to. You will see a path like “CUsersACK” where “ACK” is the username.
  • You should know which among the user account is corrupted. Just look for a key named “RefCount” and change its Value data to “0” and click OK. And if it isn’t available, simply right-click on the right pane and create it.
  • After that, double click on the key named “State” and make sure that the Value data is “0” and click OK.
  • Exit the Registry Editor and restart your computer to apply the changes made.

Option 3 – Try running 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 with good system files that might be the cause why your screen is stuck at “Preparing Windows”. To run the SFC command, follow the steps given below.

  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • 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.

Option 4 – Try to repair hard disk errors using the Chkdsk utility

You can also run the Chkdsk utility to resolve the problem. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the Chkdsk utility comes in. The Chkdsk utility repairs hard drive errors that might be causing the problem.

  • Open Command Prompt with admin privileges.
  • After opening Command Prompt, execute the commands listed below, and don’t forget to hit Enter right after you type in each one of them.
  • chkntfs /t
  • chkntfs /t:10

Intel i9 Alder Lake better than AMD Ryzen 9
Alder LakeIf we are to believe news from Intel, new series of processors based on Alder Lake architecture are about to be released somewhere in October. Alder Lake is the 12th Generation Core of Intel processors and it is meant to have all advantages of the current CPU structure. I9 is aimed to pack a punch against its competitors with technology including eight high-performance Golden Cove cores (P-cores) with Hyper-Threading and eight energy-efficient Goldmont (E-cores) equipped with a 30MB L3 cache and operating at high clock speeds. During the benchmark test, the new CPU outperformed all of Intel’s previous Rocket Lake structure processors which is logically expected but the big surprise came from results that indicate better performance than Apple’s new M1 processor even in single-threaded performance which is supposed to be best in that field. Another surprise was really beating AMD Ryzen 9 in each field. If we take into account that i9 has 16 cores in total and can process 24 threads against Ryzen 9 with 16 Cores and 32 threads this is an impressive feature. Now truth to be told Alder lake has massive L3 cache and microarchitectural advantages and consumes much more power but the results of performance are high. Also, note that this early CPU is not really a mass production one and maybe some things will still change but early results are very satisfactory. We will see what will price tag be since in this age of shortage and competition that will also play a big role in its overall success. Speaking of competition I eagerly await AMD’s response to this, in any way it seems that the CPU market is for some turbulence which is always a good thing for the final customer and I welcome it.

How to Fix Windows Setup Error 0x80300002
Installing a Windows 10 upgrade is definitely not an easy task since the process is not always smooth sailing and you could encounter some errors when doing so. This isn’t unusual since there are various software configurations and hardware configurations as well as services it depends on in order to properly work. So if any of them malfunctions or becomes corrupted, it will affect the process which will result in errors like the error code 0x80300002. When you encounter this kind of Windows Update error, you will see the following error message on your screen:
“We couldn’t install Windows in the location you choose. Please check your media drive. Here’s more info about what happened: 0x80300002”
You can encounter this kind of error if there is corruption in the partition table of the drive where the installation is in progress. In addition, corruption on the Media device could also cause this problem. So if you encounter this error when running Windows Setup, read on as this post will guide you in fixing it. There are several ways to resolve this issue. The first thing you can do is to verify the compatibility between the BIOS and the installation media. You could also try recreating all the partitions as well as recreating the bootable USB drive. For more detailed information, follow the given options below.

Option 1 – Check if the BIOS is compatible with the installation media

The first thing you can do to fix the error is to check if there are any compatibility issues between the BIOS and the installation media you’re using. This is actually one of the most likely reasons why you’re getting the error since this is a complicated point for the Windows installation process. If the installation media is based on GPT, then your BIOS must be based on UEFI. So if you have your bootable media with the MBR partitioning, you need to set your BIOS to Legacy.
  • In the Windows Search box, type “command prompt” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
  • After that, execute this command: exe /convert /allowfullOS
  • Now, wait until the process is completed since you can track its process on your screen.
  • Once it’s done, go to Settings > Update & Security > Advanced Startup options and from there, click on Restart Now. This will restart your computer and give you advanced options.
  • Next, select Troubleshoot > Advanced Options where you will see further options including System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
  • Now select the “Legacy” option. This will take you to the BIOS. Boot Mode is typically available under Boot > Boot Configuration. Once you’re there, set it to Legacy and then save the changes you’ve made. After that, your computer will restart.

Option 2 – Try recreating a new bootable drive

  • Insert your USB drive into your PC.
  • Tap the Win + R keys to open the Run dialog box and type in “cmd” and tap Enter to open the Command Prompt. Alternatively, you can also search for “cmd” in the Cortana search box to open Command Prompt.
  • Once you’ve opened CMD, type in this command to open the DISPART utility – diskpart
  • After that, you should see a new black and white window that would say, “DISKPART>”.
  • Next, type in “list disk” in the command line and tap Enter to see the list of all the Storage devices as well as your hard disk connected to your PC. Here, you have to identify your disk’s number.
  • Type in this command where “X” is the disk number you have identified and then tap Enter – disk X
  • Type in this command and hit Enter to clear the table records and all the visible data on the drive – clean
  • Now you have to recreate a new primary partition of the drive so you’ll have to type in this command and tap Enter right after – create part pri
  • A new primary partition has been created so you have to select it by typing this command and tapping Enter – select part 1
  • Now you have to format it to make it visible to normal users by typing – format fs=ntfs quick
Note: If your platform supports the Unified Extensible Firmware Interface or UEFI, replace the “NTFS” with “FAT32” in the command on Step 10.
  • After that, type in this command and tap Enter after – active
  • Finally, type this command and hit Enter to exit the utility – exit
  • After you prepare the image for the operating system, save it to the root of your USB Storage device.

Option 3 – Try to recreate all the partitions

If none of the first two options given above worked, then you can try to recreate all the partitions instead. All you have to do is restart the Windows installation process and wait until you get to the part that says, “Where do you want to install Windows?”. From there, you will see options like delete, format, extend, create new partitions, and many more. Now you have to select the Delete all the partitions options and then use the “New” button to create new partitions. Just make sure that you have one primary partition at least where you can install Windows 10. After that, continue the installation of Windows on the new partition. Keep in mind that when you create a new partition, it also recreates the partition table configuration which means that the chances of getting an error are very unlikely.

Fix Msvcr120.dll_clr0400.dll Missing Error
DLL files have certain functions that help the programs in the computer run properly. One of these DLL files is the Msvcr120.dll_clr0400.dll. This particular DLL file is responsible for the extraction of the required resources during the installation of a program and is used when the program is launched or when games are launched in the C++ language. However, a number of users recently reported that they’ve encountered an error that says, “Msvcr120.dll_clr0400.dll is missing” when they tried to install an application or when they tried opening an application. This kind of error could be due to several factors. It is possible that the DLL file is corrupted or there are some programs that interfere with the DLL file. On the other hand, it is also possible that it has been infected by a virus. To resolve this error, here are some potential fixes you need to check out:

Option 1 – Run System File Checker scan

The first thing you can do to fix the error is to try running the System File Checker or SFC scan. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:
  • Hit the Win + R keys to launch Run.
  • Type in cmd in the field and tap Enter.

  • Reboot your computer.

Option 2 – Troubleshoot the missing Msvcr120.dll_clr0400.dll error in a Clean Boot State

You can also troubleshoot the isDone.dll error in a Clean Boot state. It could be that there are some third-party applications in your computer that are preventing the application from getting installed and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try installing the program again. 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 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.)
  • After you’ve set your computer into a Clean Boot State, make sure that you’re signed in as administrator and then try to install the application again.

Option 3 – Try to re-register the problematic DLL file

You can also try to re-register the DLL to resolve the problem. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) controls in the Windows operating system. Follow the steps below to use it.
  • Open Command Prompt as admin from the WinX menu.
  • Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
    • exe /[DLL file]
    • exe [DLL file]
Note: Replace “[DLL file]” with the name of the DLL file that was pointed out in the error.
  • After you execute the given commands, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 4 – Try to replace the DLL file with a trusted source

  • First, you need to get the new DLL file from another computer with preferably the same file version number.
  • After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
    • x86: This PC > C:WindowsSystem32
    • x64: This PC > C:WindowsSysWOW64
  • Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
  • Now type the “regsvr32 ntdll.dll” command and hit Enter.
  • Restart your PC and check if the error is now fixed.

Option 5 – Scan your computer using Windows Defender

Software Licensing Service 0xC004F009 Error
A copy of Windows gets into a grace period when it is installed on a computer which means that you can use your Windows computer without any constraints on its feature. However, if you suddenly encounter an error code 0xC004F009 then this means that the grace period has already expired. In such cases, you will see the following error message on your screen:
“Error Code 0xC004F009, The Software Licensing Service reported that the grace period expired.”
One of the possible causes of this error is that it could be that the grace period has already expired way before the system was activated which is a result of which the system is in the Notifications state at this moment. The error code 0xC004F009 has something to do with MAK-enabled computers in an enterprise when it comes to Volume Licensing. One of the reasons that this error pops up is due to the possibility that the computer was not activated yet even when it was already connected to the Enterprise. Another most likely cause of the error is when the system was never connected with the Enterprise at all and the given grace period has expired before your computer system is activated. Whatever the real cause of this error, this post will guide you in fixing it. Just refer to the instructions given below to fix it.

Option 1 – Try activating Windows using the command-line tool

  • First, you need to obtain your MAK key from the IT administrator.
  • Once you have it, tap the Win + R keys on your keyboard and then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
  • After that, type this command and hit Enter to install the product key or replace the existing one: Slmgr.vbs –ipk <your mak key>
  • Next, type another command and hit Enter: slmgr.vbs –ato
  • Once you’ve executed the given commands, Windows should be activated after it connects to Microsoft servers and then gives it some time and try to check if error code 0xC004F009 is now fixed or not.

Option 2 – Try activating Windows using your mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.
  • In the Start Search box, type in “Slui 4” and tap Enter.
  • Next, select your country and click on Next.
  • Keep the window open and call the toll-free number of the country you’re from.
  • Afterward, a confirmation ID should be given by the automated system which you must take a note of.
  • Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

Option 3 – Try to prolong the grace period

On the other hand, it is also possible for you to prolong the grace period but you might have to get another genuine Windows key for that. Before you proceed, you need to create a System Restore point first afterwards, refer to the steps given below to increase the grace period of the Software Licensing Service on your Windows 10 computer.
  • Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field then hit Enter to open the Registry Editor.
  • After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionSetupOOBEmediabootinstall
  • Next, change the value of the “mediabootinstall” key to “0”.
  • Now open Command Prompt with admin privileges and then type this command and hit Enter: slmgr –rearm
  • The command you just entered will add another grace period to your system activation. After that, you have to obtain a new key and then activate Windows.

Option 4 – Try running the Windows 10 Activation Troubleshooter

You can also try to run the Windows 10 Activation troubleshooter to help resolve the error code 0xC004F009.
  • Go to Settings and then select Activation.
  • After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

Fix MOZILLA_PKIX_ERROR_MITM_DETECTED
If you’re having some problem browsing multiple websites on the Firefox browser on your Windows 10 computer, then this post might be of help. One of the most common problems you could encounter in Firefox is mostly related to HTTPS and one of them is the MOZILLA PKIX ERROR MITM DETECTED or ERROR SELF SIGNED CERT or SEC ERROR UNKNOWN ISSUER error which means that Firefox was unable to trust certificates issued on secured websites. If you encounter the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox, this indicates that something in your network or system is interrupting your connection and injecting certificates and when that happens, Firefox won’t trust it. In such cases, one of the culprits is malware. Malware will try to replace a legitimate certificate with its certificate. Another cause is security software where it keeps a tab on a secure connection and creates a false positive, for instance:
“In Microsoft Windows accounts protected by Family Safety settings, secure connections on popular websites like Google, Facebook and YouTube might be intercepted and their certificates replaced by a certificate issued by Microsoft in order to filter and record search activity.”
And if you are connected to a corporate network, there might be a monitoring/filtering product that could be replacing certificates. Moreover, there are also users who reported getting this issue when they use the Nightly version of Firefox. And if that’s the case, you have to try accessing secure websites using only the stable build especially when it comes to payments. However, if you are not doing that, then here are some options you need to check out.

Option 1 – Try turning off HTTPS Scanning on your security and antivirus programs

Each security-based software has a security option that allows you to turn off the HTTPS scanning functionality. They may be available under different names such as HTTPS Scanning, Scan SSL, Show safe result, Do not scan encrypted connections, etc. Find what is applicable for your security or antivirus software and then try turning it off temporarily and see if it helps in fixing the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox.

Option 2 – Try to disable security.enterprise_roots.enabled

The next thing you can do if the first option didn’t work is to disable security.enterprise_roots.enabled which is an HTTPS certificate check on Firefox. Note that this is not recommended but you have to at least try in order to fix the error.
  • Open Firefox and then type “about: config” in the Firefox address bar and hit Enter.
  • After that, if an info message appears, confirm it.

Fix 0x00000016 Blue Screen Error
If you are a gamer, you might have encountered either the CID HANDLE CREATION or VIDEO TDR ERROR errors with an error code of 0x00000016 as you play a game. These kinds of Stop errors have something to do with the Graphics card driver. It could be that your Graphics card driver needs to be updated or it may be corrupted. Whichever the case is, you can try fixing this error using the given solutions below but before you proceed, make sure to create a System Restore Point first so that you can easily roll back to the previous state of your computer in case something does not go as expected.

Option 1 – Try checking if your graphics card is enabled and update it as well

Although the problem is quite massive, the fix could be as simple as enabling the graphics card if it turns out to be disabled. There might be some strange reason why your graphics card disables itself. Thus, the best and first option you can try is to check if the graphics card is enabled or not. To do so, follow these steps:
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
  • After opening the Device Manager, look for your graphics card option among the list of device drivers. Once you found it, check if it is enabled or not. If it’s not enabled, you should see a gray arrow pointing downwards. Right-click on the card and select Enabled.
  • Next, right-click on the graphics card once more and click on the Update Driver Software option and then click on the “Search automatically for updated driver software” option.

Option 2 – Reinstall the Graphics card drivers

  • Tap Win + R to open Run then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
  • From there, look for the Display adapters and uninstall each one of the graphics card drivers by right-clicking on them and selecting the Uninstall device option.
  • After uninstalling the graphics card drivers, close the Device Manager and tap Win + R to open Run once again.
  • After that, type “appwiz.cpl” in the field and hit Enter to open Programs & Features in the Control Panel.
  • Next, look for any program that’s related to your GPU manufacturers like Nvidia, AMD, or Intel. Right-click on any GPU-related entry and click on Uninstall to uninstall them and then follow the next on-screen instructions that appear afterward.
  • Now restart your computer.
  • Once your computer has restarted, go to the GPU manufacturer’s website and download the latest driver version for your graphics card model and then install it.
  • Restart your computer once again. That should fix the problem.

Option 3 – Try reinstalling the game

If updating and reinstalling your Graphics card driver didn’t help, then you can try to reinstall the game where you’re getting the CID HANDLE CREATION or VIDEO TDR ERRORS.

Option 4 – Uninstall the programs you installed recently

Chances are, some programs that you just installed might be the one that’s causing the BSOD error. Thus, you need to uninstall the program to resolve the problem.
  • 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. In addition, you might also want to check the hardware components of your computer that might not support the operating system itself. You can disconnect all the external devices like USB drives, scanners, printers, etc., and then reboot your PC. After that, add the devices again one after the other and check if the BSOD error is now fixed or not.

Option 5 – Try disabling your monitor’s Sleep functionality

There are times when the Sleep functionality of your monitor can also cause BSOD errors like CID HANDLE CREATION or VIDEO TDR errors. There are also times when the graphics card is running in the background and the display goes to sleep and then it’s turned back on but you encounter this kind of Blue Screen error. This is why you can try to disable your computer monitor’s Sleep mode.

Option 6 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like CID HANDLE CREATION or VIDEO TDR errors. 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 7 – Try to run the Chkdsk utility

Running the CHKDSK utility might also help you resolve the CID HANDLE CREATION or VIDEO TDR errors. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.
  • Open Command Prompt with admin privileges.
  • After opening Command Prompt, execute the following command and hit Enter:
chkdsk /f /r
  • Wait for the process to be completed and then restart your computer.
