The speed at which the CPU runs varies depending on any Windows laptop or desktop. And in case you don’t know, the CPU does not run at full speed all the time as it depends on how the operating system distributes the load so it works accordingly. However, there are instances when it runs at full speed especially if your Windows 10 computer is on a heavy workload. But if you find that even when your computer is already on a heavy workload and the CPU is still not running at full speed, then you need to look into this situation. To verify that your CPU’s speed, you can use any CPU stress test tool. This kind of issue is common on laptops compared to desktop computers since laptop runs on battery. The Intel Processor on laptops uses the Speed Stepping Technology which means that when you are doing some small tasks on your laptop, the processor’s speed is reduced. On the other hand, if this happens when you are using a heavy application, it can be due to a low charge on the laptop’s battery. Thus, Windows will try its best to keep the computer running for as long as possible by reducing the CPU speed or processor. But there are times when you are ready to sacrifice battery to make sure that the work gets done on time. To achieve that, here are some options you can check out.

Option 1 – Try setting the processor state to the maximum in Power Options

• Type “control” in the search box to view the classic Control Panel as well as the popular options.
• Next, click on Power Options > Change plan settings > Change advanced power settings.
• Then navigate to Processor power management > Maximum processor state.
• Now select 100% when it is on Battery and Plugged in.
• After that, expand the System cooling policy option and make sure to set it as Active to make sure that the battery won’t overheat.
• Finally, apply the changes made to all the profiles of the power management and restart your computer. This will ensure that your CPU will run at maximum power at all times.

Option 2 – Try to update or disable the Intel Power Management driver

The next option you can try is to update or disable the Intel Power Management driver. The Intel-powered computers have dedicated software that controls CPU speed and Fan speed when it needs to save battery. You can try disabling it temporarily and check if there are any changes with the CPU fan speed.

• First, restart your computer by holding the Shift key to boot your computer into Troubleshooting or Advanced mode.
• Next, go to Troubleshoot > Advanced Options > Command Prompt.
• Then change the directory to C:/Windows/System32/driver and then rename the file named “Intelppm” by entering the “ren intelppm.sys intelppm.sys.bak”.
• Now restart your computer.

Note: If you were not able to find the drivers in C:/Windows/System32/driver, check if they are available under C:/Drivers/IntelPPM. After that, the CPU speed should change now with the Intel driver missing from the system. And in case you want to enable it, simply follow the same steps given above and rename the file again.

Option 3 – Try disabling the IPPM using the Command Line or Registry Editor

• Command Prompt:
  • Tap the Win + R keys to open the Run dialog box and type “cmd” and tap Enter to open Command Prompt.
  • Next, type this command and hit Enter: sc config intelppm start= disabled
  • The “sc config” command you entered modifies the value of a service’s entries in the registry as well as in the Service Control Manager database.
• Registry Editor:
  • Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
  • Next, navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesintelppm.
  • From there, double click on the intelppm and change the Start key value to
  • Now close the Registry Editor and reboot your computer.

Note: The steps given will make sure that the CPU will run at maximum power at all times.

Code 0x800488AB – What is it?

The Error Code 0x800488AB will appear when a user is in the Windows 10 Mail app and has provided an Outlook.com e-mail address. The mail app will give a message that the “account information is out of date” and it does provide an option to fix the issue. After clicking the Fix button, this error code will show up to the user. Common symptoms include:

• The login information was changed on the Microsoft website and was not updated to reflect on the Windows 10 Mail app.

The Microsoft website and Microsoft Mail app do not share the knowledge of the change in login credentials, therefore the log-in credentials appear to be incorrect when trying to access the Microsoft Mail app. It should be noted that a user may bypass the password option if they log in to the Microsoft Mail app while using the alternative PIN log-in method, thus still leaving the password undetected.

Further Information and Manual Repair

As is the case with all new technology and having a few wrinkles, the release of Microsoft Windows 10 is not left out. There have been a few discussions of errors and bugs, including Error Code 0x800488AB. As of right now, there are three different methods that can be utilized by any at-home user.

The file is too large for the destination file system is the error when you try to copy a file larger than 4GB on a drive formatted in the FAT32 file system. FAT32 is the old file system used in previous Windows versions and it was replaced by superior NTFS, altho FAT32 is still used because of its compatibility fact that it could be accessed in various operating systems its disadvantage among others is that it can not hold files larger than 4GB in size. This refers to the size of a single file, so if you have a file that is this large and when you try to copy or move it on a drive formatted in FAT32 you will get this message, and the operation will not be able to complete.

Format drive

In order to actually transfer the file in its glorious size, I am afraid that you will need to format destination drive in NTFS or if you have data on drive which you do not want to lose with formatting, use third-party software to convert file system from FAT32 to NTFS without losing data. I would recommend AOMEI partition assistant, it is a free and proven application letting you both manage your partitions and convert any one of them into another file system without data loss. You can get AOMEI here.

Split file

Another option if you are not keen on installing third-party tools or formating is to divide large files into smaller ones that are less than 4GB in size. You can use any archiving application since built-in Windows ZIP support will not let you split file into various different sizes. The best tool in my humble opinion is WinRAR, but you can choose any proven one. When file is split into parts less than 4GB in size, you will have no issues copying or move the file to the destination drive.

In Installing or upgrading your Windows 10, there really is no guarantee that everything will go smoothly as there are times you encounter errors like the “ We couldn’t install Windows 10, 0x8007002C - 0x400D ” error message among other Windows update/upgrade errors. When you encounter this particular error message you will the following message on your screen:

 “We’ve set your PC back to the way it was right before you started installing Windows 10. 0x8007002C-0x400D The installation failed in the SECOND_BOOT phase with an error during MIGRATE-DATA operation”

This kind of Windows upgrade error indicates that some of the files needed for the installation are locked out for some reason and that Windows was not able to migrate them to a new version. It could be that your computer does not have sufficient space for those files. Thus, no matter how many times you try to upgrade your computer, you always end up going back to the previous version of Windows. To fix the “0x8007002C – 0x400D, The installation failed in the SECOND_BOOT phase with an error during MIGRATE-DATA operation” error, here are some suggestions that might help:

Option 1 – Disable your antivirus program

There are times when the antivirus program installed in your computer blocks file access and even disk access. Thus, disabling the antivirus program or any security software installed in your computer is always a good idea you can try when the Windows Update process does not go smoothly. So before you try updating your computer again, make sure to disable the antivirus or security program and once the Windows Update is done, don’t forget to enable the antivirus program back again.

Option 2 – Perform a Disk Cleanup to free up disk space

Chances are, some unnecessary files in your computer might be interrupting the installation process which explains why you’re getting the “0x8007002C – 0x400D, The installation failed in the SECOND_BOOT phase with an error during MIGRATE-DATA operation” error instead so you need to perform a Disk Cleanup in order to fix the problem.

• In the Cortana Search box, type “disk cleanup” and click on the related search result.
• Then select the disk you want to clean and click OK.
• Wait for the process to be completed and then restart your PC and try to install the Windows upgrade again.

Option 3 – Get rid of any file protection software

The Windows setup migrates the folder from one version to another during the upgrade. However, if some of your folders, if not all, are protected using some file protection software, then Windows won’t succeed in moving the folder and you will encounter this Windows upgrade error instead. Thus, you need to unlock all those protected files or better yet uninstall the file protection software after you remove the locked files. After that, try installing the upgrade again.

Option 4 – Rename the SoftwareDistribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.

• 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 stop bits rename c:windowsSoftwareDistribution SoftwareDistribution.bak

• After entering these commands, it will stop the Windows Update Service, the Background Intelligent Transfer Service, and rename the SoftwareDistribution folder.
• Next, got to the C:\Windows\SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
• Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.

net start wuauserv net start bits

Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.

Option 5 – Run the DISM tool

As mentioned, the “0x8007002C – 0x400D, The installation failed in the SECOND_BOOT phase with an error during MIGRATE-DATA operation” error might also be caused by corrupted files in the computer. Thus, you can try using the DISM tool to repair them. Running the DISM tool can repair the Windows System Image and Windows Component Store in Windows 10.

• Open the Command Prompt as admin.
• Then type in this command: DISM /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.

Option 6 – Run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve this particular Windows upgrade error. 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.

Option 7 – Try running Microsoft’s online troubleshooter

You also have the option to run Microsoft’s online troubleshooter which could help you fix Windows Update errors including the “0x8007002C – 0x400D, The installation failed in the SECOND_BOOT phase with an error during MIGRATE-DATA operation” error.
