While some applications are essential, like – Chrome and WinRAR, etc., there’s another class of apps called ‘NirSoft Utilities’ that gets less attention.
NirSoft Utilities are small programs that can perform many of the Windows tasks with ease, like monitoring your network, recover a lost password, extract media of your previously visited web pages and much more. And the good thing about them is: they all are free, weigh a few KBs and needs no installation.
Check out the following video on the top 10 Nirsoft Utilities.
Since most of Nirsoft utilities tweak the registry files, your Windows Antivirus might detect them as malware. But that’s just the case of False Positive. You can ignore those warnings; Nirsoft Utilities are safe.
Best NirSoft Utilities
Utility: Find the product key
While reinstalling Windows or Microsoft Office, you have to enter the product key you had on your previous machine. Usually, this product key is printed on the back of your laptop or on the installation CD.
But if can not find your product key, this small utility will help. Simply, run the program and it’ll extract the ProductID of all the supported programs.
Utility: See all the opened ports
CurrPorts is a small network monitoring tool that gives you the list of programs connecting to the internet, full path of the process with their open ports.
CurrPorts also let you close any unwanted connections with a single click and save all the information to HTML, XML, or tab-delimited text files. Overall, it comes in handy if you suspect malware on your computer.
Utility: Read the cache folder of Google Chrome
When you visit any website, some files (mostly images) are stored on your local drive. This way, next time you visit that website, it’ll load much faster, since now you don’t have to fetch content from the server. And the name suggests, ChromeCacheView gives you a complete view of all the files stored in the Chrome’s cache folder.
This tool comes in handy if you want to retrieve any images from the cache folder of Google Chrome. But like any data recovery software, this doesn’t guarantee any 100 percent results. Also, it won’t work in the incognito mode, as all the cache and cookies are auto-deleted the moment you close the incognito window.
Utility: Extract videos from the browser’s cache
Once you watch a video online, a copy of it is stored on your browser cache. Now say, if the video is no longer available online or you just want to download the video without wasting your bandwidth, then VideoCacheView will help.
However, keep in mind, that this is not a reliable method, as not all the videos are going to get played but if you desperately need a file back, it’s worth checking out. If you are not able to play the video file, try the latest VLC media player.
Utility: Lets you bulk manage Windows Defender Antivirus notification
WinDefThreatsView presents all the Windows Defender threats under 1 window. Herein, you can select multiple notifications and choose a default action. For instance, Windows Defender will send notification and block app installation from an unidentified location. So, in case you have multiple notifications for a similar app, you can choose all of them and set default action as “Allow”. WinDefThreatsView also works for remote Windows systems but you have to make sure that you have permission to access WMI on the remote system.
Utility: Easily Changes your DNS servers
If you want to access geo-blocked content or to improve speed and reliability, then changing DNS might help.
Now, the traditional way to do it is a bit tedious. But with QuickSetDNS you can quickly switch between multiple DNS servers with just one click. There is also an option to add a new DNS record inside the app.

This way, you can switch to a less crowded channel.
Utility: Lists all system and Windows 10 default applications

It provides the application name, installation folder, uninstallation command, registry name, last modification date, the user who installed the app, etc. The best part is you can batch uninstall applications at once. The only downside is InstallView doesn’t show non-Windows desktop applications installed manually via the Internet.
