Windows uses 2 types of keys for its activation, KMS or MAK. These keys should work without any issues since they are elevated with higher permissions but in some cases, they are by accident run without their proper permission, and then we have access denied error or error 0x80070005 To resolve this issue please first check if not by any chance your antivirus or firewall is preventing slmgr.bs file to access the right permissions, that being said if the previous solution is not working note that you have to be an administrator of the system or have administrator privileges. As an administrator, you will have to use Software Licencing Management Tool or short SLMGR.VBS, a VBS file in Windows used for its activation purposes. As an administrator, open Command prompt with admin permissions and then run slmgr.vbs This will make sure that activation goes through, make sure to use proper options like:

/ipk <ProductKey> or /ato [<Activation ID>]

When we initiate the copy or move files command we get a dialog that shows us the progress of the current operation, under that bar we can click on the little arrow to expand the bar into so-called more details view where we get more information like which file is being copied, more detailed graph, etc. Windows will remember the last option we had and next time when we start the same process it will open the last view. But what if we want to only have one view always open as default, even if we change it? Let's say that we always want to have a detailed view opened always as our default even if we switch to a minimal one? Well with some tweaks in the registry of Windows we can. Note that this guide will require changing things in the registry of Windows itself, it is always smart and recommended to make a safe backup of your registry, just in case.

FOR ALWAYS SHOW MORE DETAILS FOLLOW THIS GUIDE:

open notepad and paste the following code inside: Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\OperationStatusManager] "EnthusiastMode"=dword:00000001 Go to File > Save as... and once the file save dialog opens choose at the bottom all files under file type.

What is Error Code 0xC004E003?

Error code 0xC004E003 almost always appears when there are damaged files in the Windows operating system. These files could be corrupt for a number of reasons and are usually a serious danger to the life of the computer system. These file errors may be caused by a number of things. Incomplete installation setup, incorrect deletion of hardware or utilities, or an unfinished file erasure. The trigger might also be in the event that the computer system is contaminated with a virus or adware or spyware, or even by the improper shut down of the computer. Any of these scenarios have the possibility to result in the removal or corruption of data of the Windows system data files.

The data system files that are damaged will give linked data and archives that are missing or wrongly linked. These are needed for the proper functioning of the software. This can also happen when or after installing third-party software that might have changed the system files. If it is suspected that a program installation will need to be stopped, it is best to let it run through the setup and then delete it later. While it installs, it is altering program files, and likely rearranging them. Stopping this in the middle can scramble files associated with the program and files vital to the usage of the computer.

Solution

Error Causes

This error will pop up after installing third-party software that has changed the system files. These system files are necessary to finish the activation process.
