Installing Windows on a new system is way more complicated than just upgrading it to the newer version. It seldom freezes up or crashes with error messages on the screen. One of those such error messages is “Windows could not complete this installation. To install Windows on this computer…“. There may be a lot of reasons that may cause this issue in the first place, but you have to manually appear at a solution in this case.
Fix 1 – Try using an administrator account
You should create a new administrator account and retry installing.
Step 1 create an Admin account
1. While you have received the error message, press the Shift+F10 keys together. This will open up the CMD terminal.
2. Now, type these two commands one by one in the terminal and hit Enter to create a new administrator account.
net user administrator /active:yes net user administrator mypass
3. When you have done that, tap on “OK” on the error message to proceed further.
This will open up the installation window and you should be able to finish installing Windows without any further error messages.
Step 2 – Run Microsoft Out of the box experience
If this doesn’t work out, the same error message will come back.
1. The Command Prompt terminal should be automatically opened up.
2. Now, copy-paste these two codes one by one and hit Enter.
cd oobe msoobe
Upon executing the second command, you will see that the ‘Set up Windows’ window has appeared. Just, follow the on-screen steps to set up your Windows and tap on “Start” to start the installation process.
Step 3 – Run MMC
If you see the same error message again, follow these steps –
1. If you see the error message once again, press the Shift+F10 keys together.
2. Once the terminal opens up as an administrator, just execute this code.
3. When the Console opens up, tap on “File” on the menu bar.
4. Then, tap on “Add/Remove Snap-in…“.
5. After that, tap on the “Computer Management” on the left-hand pane and tap on “Add>“.
6. Next, tap on “Finish“.
7. Now, on the left-hand pane, expand this way –
System Tools > Local Users and Groups > Users
8. You will see the list of users and groups.
9. Now, right-click on the “Administrators” account and tap on “Properties“.
10. Then, uncheck the “Account is disabled” box.
11. After that, tap on “Apply” and “OK“.
12. Again, right-click on the “Administrators” account and tap on “Set Password…“.
13. Next, tap on “Proceed” to go to the next step.
15. Next, write down a password in the ‘New password’ and ‘Confirm password’ boxes.
16. After that, tap on “OK“.
17. Finally, tap on “File” in the menu bar and tap on “Save” to save the settings.
Close the Computer Management window.
Then, retry the installation process. This should solve your problem.
Fix 2 – Reset the PC
Resetting the PC has worked for many users.
1. At first, turn off your computer.
2. Simply press the power button to boot up your system.
3. Then, when your system boots up, press-hold the power button again to force shutdown your system as soon as the Windows logo starts to appear.
4. Continue this 2-3 more times and you will reach the Automatic Repair screen.
When your computer boots up, you should be in Recovery Environment mode.
5. Then, tap on the “Advanced options“.
6. Next, tap on the “Troubleshoot” to access it.
7. After that, tap on the “Reset this PC” to reset the system.
8. Then, tap on the “Keep my files” option to reset your system but keep all of your files.
Now, your Windows system will restart and fix the system in the process.
9. Finally, tap on “Continue” to proceed to Windows.
You may lose some recent apps or settings, but this should solve your problem.
Fix 3 – Reinstall the deactivated system
While installing the latest version of Windows 11, you may have seen the page where it asks for the activation key. Some users have reported that bypassing this activation request and then installing Windows has worked for them.
So, when the Windows installation process requires you to input a product key, tap on the “Skip” or “I don’t have a product key” option. Now, complete the rest of the installation process.
After you have installed Windows, you can activate it from the Settings window.
System > Activation
Now, you can use your product key to activate your system.
Fix 4 – Use another media source
If you are using a Windows 11 DVD, try altering the media source you are installing it from. You can use a Media Creation Tool to create a new bootable drive. This way, you can use this new bootable media drive to install Windows again. This should solve your problem.
