3. The drive letter of system partition has been modified.
4. Computer doesn't transmit all files during updating software.

Solutions to fix the error

Now that causes of the error are not exclusive, solutions vary largely. This article provides a couple of solutions which have been tested effective in solving this error.

Method 1: Check date and time settings

This solution sounds ridiculous but it does works for many users. If time or date is incorrect, it'll have bad effect on Windows update service and it's necessary to check settings of date and time first when you get the error, which is quite easy.

Step 1  Click "Date and Time" on the lower-right corner of screen and click "Change date and time settings".

Step 2  You'll see the "Date and Time" window and click the "Change date and time" button.

Step 3  The previous brings about the "Date and Time Settings" applet where you should set correct date and time. Then Click "OK" to save changes.

Now restart computer and try to install system updates. If this method doesn't work, please move to next solution.

Method 2: Remove Windows update files

If you get 0x80070002 error because of failed system update process, which means some files are corrupted. Hence, we should delete those files and try Windows update once again. You can follow these steps to settle the problem manually.

Step 1  Stop Windows Update service.

1. Click "Start" button and select "Control Panel". Type "Administrative Tools" in the search box and press Enter.
2. On the pop-up windows find and double-click "Service". If you are asked to provide administrator password or confirmation, type password and give confirmation.
3. Click the tab "Name" to sort items alphabetically, after which you can find out Windows Update service easily. Right-click it and select Stop. For Windows XP users, please find out Automatic Updates and right-click it to select Stop.

Step 2  Delete corrupted update files in Software Distribution folder.

1. Open My Computer and double-click drive C where operating system is installed.
2. Open Windows folder and double-click SoftwareDistribution folder to open it.
3. Open the DataStore folder and delete all files and folders in this folder. Then back to the SoftwareDistribution folder and double click Download folder to delete everything in it.

Alternative operation of step 2 is renaming the SoftwareDistribution folder as old if you don't want to delete files. Click Yes if you are prompted by UAC (User Account Control) warning.

Step 3  Restart Windows Update service

Method 3: Use Windows Update troubleshooter

Another common way to cope with the issue is using Microsoft Fix It Tool which can be downloaded online. This tool is able to automatically diagnose and fix common problems with Windows Update.

Method 4: Make Primary Partition as Active

One less common reason of 0x80070002 is that operating system is installed on a partition which is not activated. If you get into this situation, there are two ways you can choose: one is to repartition hard drive and reinstall Windows, which is not suggested, as repartitioning hard drive removes everything; the second option is setting system partition to active.

You can do this manually in Disk Management, but I'd like to recommend the use of DiskGenius which is a powerful partition managerpacked with diverse features and makes it easy to manage partitions and disks and recover lost data.

Step 1  Install and run DiskGenius and you can see disk and partitions information displayed clearly on the main interface.
