Restarting is especially helpful, you have been keeping your computer on sleep mode for a long time.

Turn off your computer and turn it back on, and then check if the error would appear again.

To restart your computer even more effectively, if you use a desktop computer, you can just unplug it from the power strip and plug it back in after a couple of minutes. If you use a laptop, and its battery is removable, remove its battery and reinsert it after a minute or two.

Note: In order to be able to access the troubleshooter, you may have to access the Safe Mode first (feel free to check the don't know how to boot in Safe Mode guide, if you are not sure how to access it), in the event if this error message blocks your computer from turning on.

It is possible that one of the programs installed in your computer doesn't function properly, preventing Windows updating to take place, Office to be activated, or an app to be installed, and 0x80070005 error to appear on your screen. Uninstalling the program is the easiest part, however, finding which program is causing this issue isn't, especially if you have many programs installed.

To find the bad program, and remove it, start your computer and make it run only the essential Windows components, without the programs installed in your computer, i.e. do a "clean boot".

If you have never done a clean boot before, follow the steps below:

1. Press the Windows key + R key on the keyboard to open the Run window;
2. Type msconfig.exe and click on OK;
3. Click on the Services tab, tick (check) Hide all Microsoft services to avoid turning one of them off accidentally, which might result in system instability;
   
   

   
   
   

4. Disable all third-party programs you installed, by unchecking the check boxes next to them;
5. Click on Startup and disable all the programs that run when Windows starts;
6. Restart the computer.
   
   

After the computer turns on, run the programs one by one. Once you identify the program which is the reason for this error message, uninstall it or remove it.

Reliable Internet connection is a must for Windows to be updated properly, Office to be activated, or Windows apps to be installed. Stable Internet connection is a must for every other process involving downloading of files from an external source. If the Internet connection is not reliable, error code 0x80070005 can pop up. Therefore, make sure that the Internet connection you are connected to is good. Also, if possible, update your device through an Ethernet cable, and not Wi-Fi, as Ethernet (wired) connection brings you the most out of your connection.

Common tips to improve the quality of your Internet connection, if restarting the router or modem won't help include:

1. Bring your router closer to your computer;
2. Buy a signal booster;
3. Use an underused router channel;
4. Upgrade your Internet plan;

When viruses invade a computer, they cause nothing but trouble. When invading, they can damage your computer's system files, and lead to Windows update error 0x80070005 to appear. If this error is caused by viruses, all you need to do is to scan your computer with an antivirus software and remove every single threat, if detected. It is a popular belief that having an antivirus makes you 100% safe from viruses, but unfortunately, that's not true. Many viruses are released on a daily basis that sometimes the antivirus software isn't fast enough to respond.

To keep yourself protected:

• Don't visit suspicious websites (websites with irresistible and unrealistic offers);
• Don't open suspicious emails;
• Don't download and install programs from websites other than the program developers'.

   net stop bits
   net stop wuauserv
   net stop appidsvc
   net stop cryptsvc

It is possible that the current firewall and/or antivirus settings are causing this issue, as they have found one of the Windows update files dangerous (i.e. false-positive to viruses). The to test this hypothesis, disable the antivirus and firewall temporarily, and check if the error code 0x80070005 would still appear when installing the Windows update, or the app, or when clicking the Activate button in Microsoft Office.

If the error message appeared again, check the other solutions, but if you didn't get an error message this time, you will need to access the firewall and the antivirus settings and check how they are configured, and reconfigure them, as the same error may appear when the next Windows update takes place, too.

To disable the Windows Firewall:

1. Open the start menu and type Windows Firewall;
2. Click on Windows Firewall and then Turn Windows Firewall on or off;
3. Click on Turn off Windows Firewall (not Recommended) for both Private and Public networks:
    

To enable the Windows Firewall:

1. Open the start menu and type Windows Firewall;
2. Click on Windows Firewall and then Turn Windows Firewall on or off;
3. Click on Turn on Windows Firewall for both Private and Public networks;
   
   

Note: Make sure to reenable the Firewall and Antivirus once you have reconfigured their settings, as you won't be safe from viruses otherwise. If you don't feel comfortable to change Firewall and antivirus settings, make sure to go through help articles which can be found on the developer's website or on the Microsoft website.

Just as we need air to breathe, Windows needs free space on the hard drive to operate. Imagine Windows update, or an app, as a box you received via mail. To unpack that box, you will need more space. It's the same with installing Windows Updates or apps. You need enough disk space, especially in the partition where Windows is installed (Local Disk (C:)) so that the update can unpack itself throughout the operating system. If you don't have enough space, the update won't be able to unpack itself entirely. Freeing up disk space can fix this error code.

Tips to free up disk space include:

1. Remove photos, videos, or music you don't need, or which you have already backed up elsewhere;
2. Uninstall programs you don't use;
3. Clear cache and temp files frequently.
   
   

To learn how you can free up disk space and speed up your device, check out the running out of disk space / no space left solutions.

A last-resort option to fix error 0x80070005 is reinstalling the device's operating system.

Before you reset your computer, make sure to make a backup of your personal data (pictures, music, videos and other invaluable documents) to an external hard drive, or to an online backup solutions like Google Drive, OneDrive, etc., to avoid losing them in the process.

Feel free to check out the don't know how to install an operating system guide to learn how to (re)install your computer's operating system, safely.

To install programs, or apps, you will need administrator's privileges, as only administrators can do this action. If you are the only one using your computer, then you are an administrator by default, however, if you are using someone else's computer, or there are more than one user (visible when you turn on your computer), then maybe your user doesn't have the necessary permissions.

To fix this error, if caused by lack of administrator permissions, you would need to ask the computer's administrator to update Windows, or the app, or, otherwise, if you know the computer's password, you need to change your account's type into administrator account, by following the steps below:

1. Open the start menu and type user accounts;
2. Click on your account;
3. Click on Change the account type and enter your password;
   
   

   
   
   

4. Select Administrator as the account type;
   
   

   
   
   

5. Log out of your account and log back in;
   
   

Note: If you couldn't change the account type, ask the computer's administrator to change it, following the steps above.

Maybe the reason behind this error code are the sharing permissions of the folder where the Windows Update or the app is placed. This is especially the case, if you are trying to access a shared folder or file from another computer.

To adjust the sharing permissions, feel free to follow the steps below:

1. Right-click the folder and select Properties;
2. Click on the Security tab, select a user and click on Edit;
   
   

   
   
   

3. Click on Add and then on Advanced;
   
   

   

   

4. Click on Find Now and wait;
   
   

   
   
   

5. Click on Everyone, and on Apply and OK.
   
   

The file's or folder's permissions should be updated and this error solved.
