Solution 5 – Delete the Software Distribution folder
The Software Distribution folder is a specific folder where all data and files of Windows updates are temporarily stored. If there’s something wrong with this folder, you won’t be able to install updates.
So, we’re going to delete this folder, in order to make your Windows Update mechanism work again. Here’s how to do that:

- net start bits
- Now, try to run Windows Update and check for changes.
Solution 6 – Make sure the Update service is running
As its name says, Windows Update service is essential for installing Windows updates. Now, if you’ve wanted to skip some update in the past, there’s a chance you got this service disabled.
So, we’re going to check if this service is disabled and re-enable it, if needed. Here’s how to do that:
- Go to Control Panel
- Click on System and Security
- Go to Administrative Tools > Services
- Find the Windows Update service
- If the service is disabled, right-click it and go to Enable
Solution 7 – Run the System File Checker tool (SFC.exe)

Solution 8 – Reset the content of the Catroot2 folder
- Launch Command Prompt
- Type the following commands, hitting Enter after each command:
net stop cryptsvc
xcopy %systemroot%\system32\catroot2 %systemroot%\system32\catroot2.old /s
- Delete the content of the catroot2 folder, but keep the folder itself. You should find it here: C:Windowssystem32CatRoot2.
- Type the command net start cryptsvc.
- Exit the Command Prompt window.
Solution 9 – Run the System Update Readiness tool (CheckSur.exe)
This tool runs a scan for inconsistencies that may prevent servicing operations. After you run the tool, the CheckSur.log file is saved in the following location: .

- Install and run the tool.
- In the Windows Update Standalone Installer dialog box, click Yes.
- Wait for about 15 minutes for the tool to install. When installation is complete, click Close.
Try to install the latest Windows 7 updates again.
Solution 10 – Change DNS server settings
Some users also suggest that changing the DNS server can also help with faulty updates. That’s mainly because your network operator’s default DNS servers are not working so well.
So, we’re going to change the DNS server settings to widely-used Google DNS.
Here’s how to do that:
- Open Network Connections. You can do that by pressing Windows Key + X on your keyboard and choosing Network Connections option.
- Locate your network connection, right click it and choose Properties from the menu.
- When Properties window opens, select Internet Protocol Version 4 (TCP/IPv4) and click the Properties button.
- Now select Use the following DNS server addresses option.
- As Preferred DNS server enter 188.8.131.52. As for Alternate DNS server, you need to enter 184.108.40.206. If you want, you can also use 220.127.116.11 as Prefferedand 18.104.22.168 as Alternate DNS server.
- After you’re done, click OK to save changes.
Solution 11 – Perform System Restore

Solution 12 – Use WindowsUpdateLoopFix

This script was available on the Microsoft Answers forum, but it has since moved to GitHub for ease of management. At the time of writing, the original post on Microsoft Answer’s forum has over 1600 upvotes, so the script should be safe to use and it won’t cause any damage to your PC.
