On this page, you'll find ESXi Monitoring tools as well as Free Tools for VMware, Microsoft. This is one of the best selections of Free Tools for VMware and Microsoft. Monitoring tools for virtual infrastructure, but also backup products.
All products here are free because usually, you can upgrade to a paid product to get even more functions. Free VMware Monitoring Tools are the essentials that VMware admins can use and implement when managing virtual infrastructures running VMware or Microsoft Hyper-V. Many of them have been awarded during VMworld.
There are also other tools which are useful for IT admins and technicians. Those are more specific tools for troubleshooting Windows, Partitioning tools, Microsoft Active Directory, SQL, Exchange and other enterprise-class apps…
There is no particular order of listing those … -:)

VMware Free Utility – vSphere Alert Center – Set up alerts from multiple vCenter Servers directly to your desktop
A new free tool from VMware Fling site is out. I have blogged in detail about this tool at 4sysops.com website here. Check it out. This tool is a standalone desktop application that you install on your Windows, Mac or Linux desktop/laptop. Then by configuring the connections (datas are encrypted after on the local disk) you can have the vCenter alerts being pulled at the required interval.
I found this tool really cool and handy for consultants, vSphere admins or other people working with multiple vCenter server environments. I'll definitely put a link to the tool also on my Free Tools page.
Free SoftEther VPN Server – The product consists of several modules (server, client, bridge) and is available for Windows (including ARM machines), Linux and MacOS, or Android/iPAD. I'm usually not a much into a VPN software solutions, but this one seems to be quite different.

VMware OS Optimization tool – my latest article is here.
VMware Has Productized one of their best Flings – VMware OS Optimization Tool (OSOT). If you have been around a long time enough you certainly remember this tool as a Fling, but no more. VMware has officially made it available within the Customer Connect portal. I think this tool is one of the Best Desktop Performance Optimization Utility.
While VMware builds this tool in the first place for VMware Horizon as an optimization utility for VDI, you can also use it to optimize your desktop or laptop systems. It's easy to use and you can revert back to the original state if you need to. Also, you can copy the built-in template and edit the copy so it fits your needs. Really handy.
You can optimize Windows 11, Windows 10, Windows Server 2019 or Windows Server 2022. Windows OS Optimization Tool for Horizon optimizes virtual desktops and RDSH servers for Horizon, and Horizon Cloud.
The tool has been newly updated which you can download via Customer Connect portal. It's a fast utility that can optimize different settings which slowing down the VDI desktops when using default settings only. Many services, registry settings, scheduled tasks etc….
Free Backup Tool for Desktop OS – One-Click Restore software from Keriver is able to do a full, incremental or differential images of the underlying OS. If you look for a tool that does provide some kind of central management console, this is not the tool you should be looking for. It’s a rather simple tool for few individual desktops. In the past, I've been using well-known names like Norton Ghost or Acronis, which are a long time being on the market, but today I stumbled through this too and I thought that it’s worth sharing…

Core Configurator 2.0 – free config tool for Windows Server 2008R2 Core – works with Windows Server 2008R2 x64 core only. The tool is provided as an ISO, so to run the Core Configurator 2.0 just mount the ISO and run Start_CoreConfig.wsf. Here is the link to the developer's page: https://coreconfig.codeplex.com/
(This tool is getting old). vCenter Pre-Upgrade Checker – The VMware vCenter Pre-Upgrade Checker not only detects problems but also miss-configuration and can avoid performance problems after the upgrade. The tool produces an output single zip file. Inside of this zip file, there is the database signature file and also the message log from running the upgrade checker tool.
AOMEI PE Builder – Supported on Windows 7/8 based systems (x32 or x64) but also on Windows Server 2008/2012 based systems. The server platform support is a good thing in the case that you’re system administrator and maintaining physical server boxes.
It allows creating Win PE bootable environment without installing Microsoft WAIK. The tool has also some built-in tools and additionally, you can add your own utilities very easy which gets exported to the final ISO.
Note: You can install it only on Win 7/8 (not 8.1) or server 2008/2012 (not R2). But once created you can use it to boot systems from windows XP/2000/Vista/7/8/8.1 and Server 2000/2003/12008/2012…. Product page.
WinDirStat – Windows Directory Statistics. This free software helps you to find out where all your disk space has gone. It is free and open-source graphical disk usage analyzer for Microsoft Windows. We have previously reported on a different, but similar, software called Tree Size Free which has also a paid alternative. WinDirStat was re-programmed for Windows from Linux by Bernhard Seifert. The original program is based on Stefan Hundhammer's program KDirStat. The software is distributed under GNU General Public License v2.
Depending on which user you are, your Windows OS can become slower and slower over time and is eating more and more disk space. One day you might wonder Where all my disk space is gone? The files can be literally anywhere, usually hidden in sub-directories. To check all different sub-trees and folders manually and see if there are some high capacity files, it's impossible. One would have to open and collapse hundreds or thousands of directories. Download Page of WinDirStat.
PuTTyTray – It's a free tool which can be personalized and which is cool. One of the personalization possibilities is, as you can imagine and according to its name, to have it running in Windows tray with eventually an option to open the window with a simple click. The personalizations can be done via Right clicking the app > Change settings.
- Minimizing to the system tray (on CTRL + minimize, always or directly on startup)
- Icons are customizable
- Blinks tray icon when a bell signal is received
- Configurable window transparency
- URL Hyperlinking
- Portability: optionally stores session configuration in files (for example: on a USB drive) like portaPuTTY
- Easy access to the ‘always on top' setting (in the system menu)
- Android adb support
Setting up appearance or hyperlinks. Source Website: PuttyTray
Remote Utilities – remote control over the remote system over LAN or WAN (passes through the router, like Teamviewer or Anydesk). Check the detailed post >>
- Security – IP filtering allowing to restrict access to only certain IP addresses. Whitelist the ones you need, or blacklist the ones you don’t…
- protection settings – remote users can’t change the settings on their machines
- Attended access – remote support via the agent module. No installation is necessary in this case.
- One to Many – connection to multiple machines at the same time from a single machine
- AD support – PCs attached to Microsoft domain appears automatically in the directory tree when preinstalled with the software. (cool…)
- Address book sync – can sync with other technician’s machines which provide the support for your company. The address book is also backed up every day.
- iOS and Android support – you can use Android or iOS devices to manage the network
- Remote settings – you can change the settings for the remote machine from the main console
- File Transfer – you can transfer files to and from.
YUMI – Yumi provides you with a list of pre-programmed Linux Distributions and Utilities that are available for multi-boot USB creation. You can choose any of those tools from a drop-down menu. A second step is to point to the ISO file so YUMI can extract the necessary files and copy them to the particular folder on the USB stick. YUMI has almost all distros of Linux but also antivirus, system tools and other utilities which can’t be put into a particular category but shall be on every administrator’s USB stick toolbox. Download YUMI. Check How to Create Multiboot USB Stick With Veeam Recovery ISOs for Different Systems.
VMware Converter Standalone – This is a free tool from VMware that everybody knows. Use a converter to do P2V conversions, adjust Virtual disk size during V2V conversions, change from Thick to thin … See how to shrink VMDK size in my post here.
You can check my post on How-to disable the SSL to speed up the conversion process. If you have many VMs to convert, want to speed up the conversions by disabling SSL via script. From v. 5.0 of Converter, there is the possibility of alignment of converted VMs on a destination datastore. Converter 6.1.1 supports conversion from Hyper-V v3 VMs (powered off) and also Windows 10 systems.
StarWind V2V Converter – StarWind V2V Converter allows the conversion of VMs from one format to another, basically “cloning” them and keeping the original file intact. P2V conversion does everything. It migrates the server OS including its configuration and all applications running on that server, into a virtual machine. With VMware converter we had an option to do P2V into VMware ESXi, but not into Hyper-V. StarWind V2V Converter allows both. StarWind V2V Converter Free is available at this link.
You can gain up to 30% in performance. See my post on it here. It can be used as “Poor man's DR solution“. It's the same version which is bundled with vSphere Essentials, Essentials Plus or higher versions of VMware vSphere. In case you need the Cold clone ISO – you can get it from my Google Drive Folder. (UPDATED). Get Dropbox with with 5Gigs of free space.
VMware Player – VMware Player is great for doing some demos or testing. It lacks a lot of features from VMware Workstation like snapshots, connection to the vSphere infrastructure and many others, but I like to use it because it's very lightweight and handy and the recent features like unity are really great… You can have your VM in the background and the windows and programs executing inside this VM are “in front”. The unity mode is just signaled by a red icon on the window. You will not see the VM player windows floating on your desktop, but the applications.
RVTools – Quick inventory can be done with this free tool from Rob de Veij. It's a small MSI package which after installation can list information about CPU, memory, disks, NICs, cd-ROM, floppy drives, snapshots, VMware tools, ESXi hosts, and datastores. Download RV Tools from here. Pretty useful to quickly gather different information about your infrastructure.
Putty is used for remote SSH to the VMware ESX service console and Linux servers or desktops. Putty is one of the “classic tools”. Everybody knows putty…. there is also putty portable you can carry around on your USB stick. You can download Putty Here and Putty portable here.
svfAlarms – By chance, I stumbled through this free GUI utility called svfAlarms, which enables you to import and export vCenter Alarms. There are some 37 default alarms in vCenter 4, 55 default alarms in vCenter5 and 61 default alarms in vCenter5.1 Alarm definitions can be fairly complex and to manage and document alarms, duplicate them across multiple vCenter installations and also to keep a managed state can be time-consuming for administrators. The sfvAlarms utility can help simplify the alarm management task. Read my post or Download the utility.
ESXi-Customizer – user-friendly GUI tool from Andreas Peetz, that automates the process of customizing the ESXi install-ISO with drivers that are not originally included. Unlike other scripts and manuals that are available for this purpose, ESXi Customizer runs entirely on Windows and does not require any knowledge of or access to Linux. Read my detailed post or download the tool.
Find inactive computer accounts in Active Directory – AD Tidy Tool – After running a reporting tool which brings results, you can select the desired records and do some actions, like disabling, moving, adding/removing to/from groups etc. You can also set expiration data on objects.
The tool uses powerful filtering options and can do a lot of actions. You can also build your own action sequences or export pie charts. The creator of this tool is Chris Wright from the UK.
GParted Live ISO – I'm sure that everyone knows this tool. But still, I want to share my recent experience. You know that with the new hosts I got for my lab there is the Supermicro's iPMI remote management, and I found myself too lazy after all. All you need to do to attach a GParted Live ISO, then boot the system on it and then do what you have to do. No need to burn the iso or to create a bootable USB stick.
The GParted Live ISO can directly attach to the system, you boot on it and it can be used to format or create partitions on local disks. Check their website at www.gparted.org or my post how-to wipe local disks and prepare them for VMware VSAN
VMware Network port diagram – get it from this page.
vSphere 6.0 ESXTOP poster quick overview of troubleshooting.
Then there is another interesting diagram about Memory management.
VMware vSphere 6 Memory Management and Monitoring diagram explain not only the four principal memory management techniques that vSphere 6 uses.
VMware uses a number of memory reclamation techniques when under pressure.
Transparent Page Sharing – This (pre 5.5 U4) used to share common pages between all guests on the same host. Now it’s shared pages on each VM because of security concerns (can be tweaked). See this article
Guest Ballooning – This is an in-guest driver that asks the guest operating system for system resources to force the guest to swap intelligently
Memory Compression – Pages are compressed and stored in a cache setup on main memory (set to 10% of total memory by default)
Hypervisor Swapping – Hypervisor swaps pages to disk… bad on performance.
I'm sure that you have already seen the diagrams like those and I'm sure that you recognize the author – Hany Michael who works for VMware -:). Get your copy.
