This part provides 3 solutions to solve Windows update 0x80070001. You can use the methods mentioned in the passage to try to solve the error.

Way 1. Disk Conversion (If Applicable)

If you come across a Windows update0x80070001 error while attempting to install Windows on a system with a Dynamic disk configured for your OS partition, the disk type is likely the cause of the problem.

A Dynamic disk allows the creation of a volume that spans across multiple physical disks.

To avoid installation issues when installing Windows, it is advisable to use a Basic disk instead of a Dynamic disk.

Note: Please note that this process may lead to data loss, so it is crucial to back up the data on the Dynamic disk via disk backup software as a precautionary measure.

To resolve the problem, follow these steps to convert the disk type:

Step 1. Press the Win + R keys simultaneously to open the Run dialog box.

Step 2. Type diskmgmt.msc in the Run dialog box and press Enter.

Step 3. In the Disk Management window, right-click on the volume you wish to convert to a Basic disk and select the option to Delete Volume.

Step 4. Next, perform a right-click on the dynamic disk and choose the option to Convert to Basic Disk.

Way 2. Remove Unnecessary Files

Insufficient disk space can also trigger this error message. As mentioned earlier, the 0x80070001 error often occurs when Windows encounters difficulties copying installation or updating files from the media to the hard drive. If there is not enough free space on the hard drive to accommodate these files, an error may arise.

To prevent this error, it is recommended to delete unnecessary files and free up space on the SSD prior to installation. One convenient method is to utilize the built-in Disk Cleanup utility in Windows. This tool scans the hard drive, identifies unnecessary files such as temporary files, log files, cached files, and other system files, and allows you to delete them to reclaim space.

Here's how you can use the Disk Cleanup utility:

Step 1. Press the Win + S keys simultaneously on your keyboard to open the Windows Search utility.

Step 2. Type Disk Cleanup in the search bar and click on the corresponding result to open it.

Step 3. In the Disk Cleanup window, select the SSD drive that you wish to clean up and click OK.

Step 4. Next, choose the types of files you want to delete, such as temporary files, recycle bin files, and system files, and click OK.

Step 5. Click on Delete Files to initiate the cleanup procedure.

After the process has finished, close the utility. Additionally, you can navigate to the Apps & features section within the Windows Settings app and locate any programs that are no longer required. Removing these programs from the system will create additional space, facilitating smooth installations of new software.

Way 3. Alter the Windows Registry

When trying to install an identical version of an operating system on your computer, you might come across the Windows 11 update 0x80070001 error caused by outdated registry files that lead to conflicts. To resolve this problem, you can validate and repair these files.

Step 1. To access the Run dialog, simultaneously press the Win + R keys.

Step 2. Enter regedit into the text field and press Enter.

Step 3. In the User Account Control prompt, click Yes.

Step 4. After opening the Registry Editor, navigate to the following location:

• HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate

Step 5. Within the right pane, locate the entry labeled WUServer.

Step 6. Perform a right-click on it and select Delete.

Step 7. Similarly, remove the WIStatusServer value using the same method.
