WSUS (Windows Server Update Services) is a fundamental, free add-on program and network service developed by Microsoft which assists IT administrators in the effective management of the download and distribution of updates, patches and hot-fixes released for Microsoft software products to Windows Server operating systems in their network through the use of automation and continuous analyses.
WSUS, previously known as SUS (Software Update Services), is particularly useful for small to medium sized businesses, acting as an intermediary between basic Windows Update used in individual PCs and more complex Systems Management Servers used in larger companies, and since expanded, it can also distribute service packs, security updates, device drivers, feature packs as well as update roll-ups, hot-fixes and more to client computers from a centralized server.
Here is our list of the top WSUS Tools:
- SolarWinds Diagnostic Tool for the WSUS Agent – FREE TOOL A free system verifier that tests connections between a WSUS server and client. Installs on Windows Server.

The management and distribution of updates through a WSUS server is completed through a management console with the aim of giving administrators full control, allowing them to direct workstations connected to the WSUS server in the network while simultaneously restricting the end users’ access to Windows Update.
Administrators can further determine to utilize a single WSUS server as the update source for other WSUS servers (known as an upstream server) in an organization, providing it connects to Microsoft Update to obtain available update information, or choose which WSUS servers can connect directly to Microsoft Update based on network configuration and security.
Maintenance & Deployment
The maintenance and deployment of interim software releases through the use of automatic updates aids in preserving operational efficiency and stability within an organization, as well as minimizing the threat of potential security vulnerabilities by maintaining properly configured systems, installing of the latest software and updates, which in turn avoids the loss of revenue or exploitation of intellectual property.
In the interest of not disrupting workflow, the Automatic Updates service runs in the background and consolidates all updates requiring a restart into a single restart, ensuring its impact on network functionality and employee productivity is minimal, while also greatly limiting its use of bandwidth when each client computer obtains its updates from a WSUS server instead of individually downloading it from the internet.
WSUS also allows for synchronization, which administrators can configure, choosing which updates are downloaded to a WSUS server during this process, and synchronization can be scheduled to initiate automatically.
Administrators can additionally group client computers to be members of a specific WSUS computer group for the easier distribution of patches based on target groups.
The overall level of compliance can be assessed and monitored per individual computer and computer group by administrators using the Status of Update report, which details the statuses for update approval and deployment per update, based on all events sent from each computer.
Update Summaries & Troubleshooting
Summaries of updates installed or required to be installed, as well as compliance information for specific computers or updates, are available and the synchronization activity and status for a given time period can be tracked, with the option of viewing all of the latest updates downloaded.
In the case of troubleshooting client computers which may be failing to report to the WSUS server, WSUS client diagnostic tools and software significantly ease and speed up this process, and we have gathered the best WSUS client diagnostic tools and software for you, detailing their capabilities and strengths, with download links and pricing structures listed under each tool.
Here's the Best WSUS Tools & Software of 2021:
Ideal for smaller networks who cannot justify a full patch management facility and the costs involved, the SolarWinds Diagnostic Tool for the WSUS Agent is a free software package which acts as a step between bare WSUS capabilities and full patch management.
Installed and run on the client’s computer, it ensures the WSUS agent works correctly on all computers linked to the WSUS server while also aiding in the troubleshooting of issues arising. This is especially handy as a troubleshooting tool when you are looking for issues relating to Windows updates on your systems.
With the Diagnostic Tool for the WSUS Agent, you will not have to rely solely on status reports by the central WSUS server, as the software provides a different view of update actions through the monitoring of client status of WSUS agents running on the endpoints on your network and validates Windows Update agent configuration values, reporting these values back to you to serve as a baseline.
This helps you to build up historical and trend data that is very helpful in the long run. It helps you to establish patterns and issues that reoccur.
The SolarWinds Diagnostic Tool for the WSUS Agent starts automatically after installation, performing an initial analysis, after which a deeper analysis can be run by clicking the Start Diagnostic button.
This will discover and reveal all potential issues with the WSUS agent, producing detailed error reports and providing recommendations on what actions are need to resolve the problem, speeding up the troubleshooting needed to have the agent running properly, while also providing the ability to run periodic checks with the aim of discovering potential points of failure before they become a problem.
Knowing ahead of time before a problem becomes serious can save an organization countless hours of repairs, as well as potential cost savings in repairs.

Syxsense Manage is a cloud-based service that is charged for by subscription. While the central console operates on the Syxsense server, local agents need to be installed on each site that hosts endpoints that are to be included in the management system. System administrators that are dissatisfied with WSUS should consider Syxsense Manager as a substitute.
The Syxsense system is able to manage devices that run Windows, Linux, and macOS and it can also supervise IoT devices. The tool, as a cloud-based system, isn’t limited to supervising endpoints on one network. It is able to centralize the supervision of endpoints on several sites and can also include remote desktops located in the homes of telecommuting workers.
When a customer starts up a new account with Syxsense Manage, the first phase of tasks is to set the system up. You need to set up a maintenance schedule that lets Syxsense know when it is OK to roll out patches. The other big task that needs to be undertaken is to populate the management system with details of the devices that are going to be managed by the service. This is an easy task because, once an agent has been downloaded, Syxsense Manage will scour the network and identify each endpoint. It then populates the system inventory with details about each device.
The next step in the setup is a software search. Syxsense Manage compiles a software inventory, listing the operating system and software installed on each endpoint. The system records the versions of all of these, which indicates the patch level that each package is at.
The discovery process is continuous so both the hardware and software inventories get repeatedly updated so there is no need to the operator to add in any new resources after the initial scan.
Ongoing, the patch manager in Syxsense Manage will watch the notification systems of all of the vendors for those software packages identified in the discovery phase. When a patch becomes available, Syxsense copies over the installer and stores it, When the next available maintenance window arrives, that patch will be applied to all relevant endpoints.
Each account for Syxsense Manage gets 50GB of space on the Syxsense server to store patch installers and also all of the logs generated by the patch manager. Those logs and all of the other system information can be extracted as reports in formats needed to prove compliance to PCI DSS, HIPAA, and SOX.
Pricing: The Syxsense Manage is charged for on a subscription with rates starting at $600 to manage 10 devices.
Download: You can download a 14-day free trial of Syxsense Manage.
ManageEngine Patch Manager Plus is one part of the IT infrastructure management tools that ManageEngine offers which aims at overcoming any potential vulnerability that can create security weaknesses. It can also help to prevent bad patches that can corrupt system data or cause a system to become unavailable.
It does all of this whilst ensuring that performance is not reduced and new features as well as resources are not missed due to unpatched endpoints.
This is all very useful if you are managing critical systems on your network and you can’t afford any downtime due to bad patches or improper patch installations.
ManageEngine Patch Manager Plus creates an inventory of the software of all endpoints. These typically exist in a network and are identified by scanning them.
ManageEngine Patch Manager Plus then compares these to the latest versions of each product.
It then details which modules are no longer up to date and then proceeds to communicate with the servers of all relevant software producers to download necessary patches.
This whole process can be automatically installed without intervention required.
However, if you require candidate patches to be approved before deployment, the patches can be listed on the dashboard for prior approval. This helps to streamline the process somewhat and is a good way to semi automate the way that your patches are selected and installed.
The inclusion of a test system by ManageEngine Patch Manager Plus assists in making the deployment of patches stable and error free, doing this by first testing the new update on a limited number of devices so that the impact of software changes can be viewed and assessed before they roll out to the entire network, saving both time and effort in the event of an issue arising, with reports on system vulnerability, applicable and missing Windows patches as well as task statuses made available.
ManageEngine Patch Manager Plus is available for on-premises installation or as a cloud-based service and while it runs on Windows and Windows Server environments, with the option of being integrated as a plug-in into Spiceworks.
Certain agents enable the software to monitor software statuses on Mac OS, Linux systems and others.
This is normally done via SNMP and can give you a lot of information about the systems that are attached to your network.
Price: Pricing for ManageEngine Patch Manager Plus Professional starts at $245.00 annually for 50 computers on-premises and $34.50 on a monthly basis for 50 computers on a cloud service and more details on pricing structure with the option of a free trial can be found below!

NinjaRMM is a package of tools that support the remote management of entire IT systems. This is a particularly interesting service for managed service providers (MSPs) because the NinjaRMM service provides all of the tools that their technicians need.
Within the NinjaRMM bundle is a Windows patch management service. This covers all tasks relating to installing patches and replaces the need to access the WSUS interface. The NinjaRMM aim is to provide all system management tools in one interface. Patch management actions implement all stages of IT asset management.
The basis of the patch management system lies in the asset discovery service of NinjaRMM. When a client is enrolled into the support service, NinjaRMM scours the network and registers all of the devices that it discovers in an asset inventory. The service then searches each endpoint and composes a software inventory for it. The result of this discovery phase is a complete list of every instance of each operating system and the software packages installed on each device.
There is no guarantee that all devices will be at the same patch level, so NinjaRMM first bring all software up-to-date by sequentially applying all missing patches. This allows the service to update the versions of all operating systems and software packages in the software inventory. Once the initial update has been completed, the NinjaRMM system continues to look out for new updates and patches and applies them when necessary.
The system administrator needs to set up the NinjaRMM Patch Manager with a calendar of maintenance windows. With this in place, the patch manager will schedule patch rollouts for the next available period.
NinjaRMM is a cloud platform and it is suitable for use by the IT departments of multi-site businesses as well as managed service providers.
Price: Contact sales team for a quote.
Download: NinjaRMM is available for a 14-day free trial.

8. ADFDesign’s WSUS Tool
ADFDesign’s WSUS Tool is a free tool available from the Spiceworks Community, handy for IT administrators with the need for cloning PCs as well as debugging and managing WSUS and it focuses on simplicity rather than complexity, being a graphical front end to actions performed in the background by the wuaucltl.exe program, which while needing to be installed on each endpoint of the network and run from there, can be controlled remotely from a central location through remote management software.
The process automation script in ADFDesign’s WSUS Tool automatically detects each client and saves time in the running of diagnostics with its three main functions of detecting, cloning and reporting.
Its “Detect Now” function runs a standard WSUS detection procedure, providing information on which of the client’s services is visible to the WSUS server and will run an audit check on the client through the restarting of the client auditing software, offering a timeframe limited report instead of an ongoing log file.
The “Clone Fix” function of ADFDesign’s WSUS Tool will attempt the process of fixing the client, deleting some registry key and restarting the wuauserv service, before resetting its authorization and re-running is detect function while the “Report Now” function will immediately run a report on a particular client, avoiding the need to dig through logs for relevant information in the diagnosing of any issues related to the client or its communication with the WSUS server.
With ADFDesign’s WSUS Tool, ensure there is no third party software used which could install malware or damage the network, as ADFDesign’s WSUS Tool only utilizes standard Microsoft executable files or programs, which you can do by combing through the code yourself.
This makes the tool quite useful if you are trying to weed out programs that you do not want installed on users’ systems.

9. WSUS Offline Tool
The WSUS Offline Tool from Anoop C. Nair addresses a shortcoming of WSUS with regards to client computers that do not have access to the internet, handled through a process called WSUS offline update which only installs critical or security relevant patches, leaving offline client computers out of sync in comparison to online computers as they can miss important updates.
The WSUS Offline Tool, however, uses the Windows Update Agent to determine what patches are required to be installed on a client’s computer, including both important and optional patches. This makes the WSUS Offline Tool a very useful application to have running on your network.
The WSUS Offline Tool schedules available patches for an offline client, delivering it from a central download server and while the patch coverage by WSUS Offline Update will rarely fully satisfy Microsoft’s Online Update, as minor patches could be missing, it does satisfy Microsoft’s Baseline Security Analyzer, but nonetheless is only recommended for use in non-production environments.
This could be useful in a lab type environment, or on a larger private network if you have the need to manage updates for multiple hosts and you don’t want to enforce it all manually.
