What is "Windows is not activated"?
The "Windows is not activated" scam is used to trick people into believing that the Windows Operating System is not activated. Scammers promote the scam using a deceptive website that looks similar to a system information window. Most users are forced to visit these websites due to potentially unwanted applications (PUAs) installed on their systems. Unwanted apps cause redirects to untrustworthy websites, feed users with ads, and collect various browsing-related data.
As mentioned above, the "Windows is not activated" scam is displayed on a website that appears like a basic system information window seen on Windows 10 operating systems. This website asks users to sign-in to a system by providing a username and password. Therefore, it is very likely that this website steals entered information. Furthermore, visitors are urged to contact "online support" via the telephone number (+1-888-295-3918) provided. Note that Microsoft has nothing to do with this website. Scammers use deceptive sites to trick people into purchasing dubious products or services. In this case, a Windows activation key. If contacted, note that these particular scammers will try to sell you dubious software. Scams such as "Windows is not activated" are used to extort money from people and, therefore, you should never trust these websites. The best option is to ignore them simply by closing the site. If a deceptive website cannot be closed in the normal way, use Task Manager and terminate the entire browser task (process) or restart the computer. Furthermore, do not restore the closed session, since this will reopen the same deceptive website.
Typically, installed potentially unwanted apps cause redirects to deceptive (scam) websites. These PUAs often feed users with intrusive ads and record data relating to browsing habits. They deploy coupons, banners, surveys, pop-ups, and other intrusive ads that are displayed using tools that enable placement of third party graphical content on any site. Therefore, they conceal underlying content. Clicking ads of this type can lead to redirects to dubious websites or they can run scripts that download/install unwanted, potentially malicious applications. In addition to these annoying, intrusive ads, most PUAs gather browsing-related data (IP addresses, geo-locations, search queries, URLs of visited websites, etc.). They also collect personal, sensitive information. PUAs developers share the details with third parties (possibly, cyber criminals) who misuse them to generate revenue. Thus, having data tracking apps installed might cause privacy issues, problems with browsing safety, or even identity theft.

The internet is full of deceptive websites that extort money from visitors in one way or another. Some examples of other websites of this type are Activate Your Windows Now, This Computer Is Blocked, and Microsoft Authorised Device Care. Generally, these websites trick people into purchasing unnecessary software or purchasing online technical support (the assistance of 'technicians'). PUAs have a similar purpose: developers promote them as legitimate tools capable of providing useful features and tools, however, installing and using them leads only to problems such as redirects to deceptive websites, and so on.
How did potentially unwanted applications install on my computer?
Unwanted apps are usually installed through intrusive ads or when installing software (typically, freeware). Software developers often use "bundling", a deceptive method used to trick people into downloading/installing potentially unwanted applications together with other software. They achieve this by hiding PUAs in "Custom", "Advanced" and other similar settings or options of the installation or download set-up. They do not disclose information regarding the presence of these bundled apps. Note, however, that inadvertent installations (or downloads) are usually caused by users who do not check settings or skip download/installation steps.
How to avoid installation of potentially unwanted applications?
Download all software using official and trustworthy sources (websites) only. Do not use third party downloaders, installers, unofficial websites, and other dubious tools. Install (and download) software patiently, check available "Custom", "Advanced" settings of the installation/download set-up. Deselect offers to install additionally-included, unwanted apps and only then finish the installation or download process. Note that not all displayed advertisements can be trusted - many redirect users to dubious, deceptive websites such as gambling, adult dating, pornography, and so on. If you continually experience unwanted redirects (or intrusive ads), PUAs might be installed on the browser or operating system. Check the list of installed extensions, plug-ins, and add-ons on your browser, and programs on your computer. Remove any unwanted, unknown apps immediately. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
