Use Disk Cleanup to delete old accumulated Windows Update files
If Windows Update is not working properly after you have run through the steps provided in the “How do I reset Windows Update components?” MS Knowledge Base article, do the following.
Reboot your computer without running any software.
Every version of Windows keeps old Windows Update files that usually amount up to many GBs of storage drive space. It is possible to delete them by using the Disk Cleanup wizard – cleanmgr.exe – that is part of Windows 10 and 8.1. An update has to be added to Windows 7 that makes deleting Windows Update and system files possible if has not been installed as an optional update. Here is the link to the required Win7 update:
Update for Windows 7 (KB2852386) –
In Windows 10 enter disk cleanup in the Search box and click on the link by that name provided above it. In Disk Cleanup, click on “Clean up system files”.
Run chkdsk or any third-party hard-drive diagnostic tools
Chkdsk (Check Disk) is the hard-drive diagnostic tool provided by every version of Windows.Running it can fix problems with the file system that Windows uses and fix other problems with the hard disk drive that may prevent Windows Update from installing updates.
There are many third-party tools of the same kind as Chkdsk, such as MHDD and those provided by the major hard drive manufacturers. The chkdsk run from a Command prompt as Administrator is te most powerful version. Visit the following page on this site for information on how to run a Command Prompt as administrator in Windows 7/8.1/10.

Run a reputable Registry cleaner
If Windows Update is still not working properly, try running a reputable Registry cleaner.
No version of Windows provides a cleaner for the Windows Registry database that configures Windows programs and settings. However, there are many free and paid-for cleaners, such as CCleaner. Run the main tool and then click on its Registry button to run its Registry cleaner, which asks: “Do you want to back up changes to the Registry.” A good idea. If anything goes wrong, you just have to find the .reg file it created and saved to a specific location and click on it to add back what was cleaned.
Reboot the system.
NOTE: CCleaner stalls other software or tools by default unless you disable the setting responsible for doing that during its installation.
CCleaner uses system monitoring and “Intelligent Cookie Management” –
Refresh the network IP addresses for your computer and broadband router
Unless set manually to a fixed IP address, every device in a network receives a unique IP Address, such as 192.168.1.254, the IP address of my router. The unique IP address for my computer on the network, created for devices connected by Ethernet cable or by WiFi to the router, has to be in the same range. Only the last number is changes. It is: 192.168.1.64.
Because releasing the IP address for your router and computer creates a fresh start with the Windows Update servers, doing so can fix Windows Update problems.
A router’s user manual should provide instructions on how to release its IP address. If not, or there is no manual available, enter your router’s configuration settings and look through the settings or ask your Internet Service Provider for that information.
My router’s IP address is 192.168.1.64. To enter its web-based configuration settings, I enter it into the address bar of a web browser (Firefox, Opera, etc.) A login box comes to the screen that requires a user name and password, which is usually on the bottom of the router and on a card that came with the router. The Wi-Fi key is also provided.
The configuration settings have a different arrangement and often work differently for every make/model of router. Here is a link to the instructions on how to change the IP address of a Linksys router:
Next, reboot the router via its configuration settings or by switching it off, waiting about 10 seconds before switching it on.
Next, release the IP address for your Windows PC. Open a Command Prompt, run as administrator, as instructed when running chkdsk. Enter ipconfig /release at the prompt followed by ipconfig /renew and reboot the PC. Note that all of the switches for the ipconfig command are provided by entering ipconfig /?
Now use Windows Update to “Check for updates”. Re-checking for updates can take a long time, because after a total reset Windows Update works as if it is running for the first time. It compares which updates are installed to the updates that should be installed and then installs any updates that are missing. So, if your computer is set to sleep after a set period, change the sleep setting in Power Options in the Control Panel to Never. Don’t forget to change the setting back after Windows Update has finished updating your system.
