"Enter Windows registration key to unblock" removal instructions
What is "Enter Windows registration key to unblock"?
"Enter Windows registration key to unblock" is the name of a technical support scam. Scammers use it to extort money from people, however, they can only do this if they are contacted in the first instance. Typically, websites of this type are opened by potentially unwanted apps (PUAs) installed on users' systems. I.e., they are not generally opened intentionally by victims of this scam. In addition to these redirects, PUAs often serve users with intrusive advertisements and collect information relating to browsing habits.
When visited, this deceptive website enables a pop-up window stating that it is a virus alert from Microsoft and that the computer is blocked. Visitors are urged not to close this window/website or restart their computers. It goes on to state that the computer is blocked due to one (or more) of the following reasons: the Windows Operating System is registered with an illegal key; there is pirated software installed on the system; the operating system is proliferating viruses over the internet; the computer is hacked or used from undefined location. To unblock and reactivate the computer, scammers encourage users to contact them via the "1800 516 5594" telephone number, or to enter the Windows registration key. To make this scam more believable, scammers designed this website to be opened in several windows - this results in having the system (or browser) crashed or unresponsive. They attempt to give the impression that the computer is blocked, when in fact the Windows or browsers simply stop working. To close this scam, we recommend that you use Task Manager and end all browser processes that keep the "Enter Windows registration key to unblock" scam active. Note that the closed browsing session should not be restored, since this will reopen the deceptive web page.
Unwanted apps that open untrustworthy, deceptive pages usually also deliver ads and collect data. They deploy coupons, pop-ups, banners, surveys, and other unwanted ads that usually conceal underlying content of visited websites (on systems with PUAs installed). If clicked, these ads open dubious websites (including scam sites) or execute scripts that download/install various untrustworthy apps, some of which might be malicious. Additionally, most apps of this type collect user-system information including, for example, IP addresses, URLs of visited websites, entered search queries, geolocations and other similar data, however, it is possible that these PUAs might also record personal details. PUAs developers continually share the data with third parties who misuse it to generate revenue.

"Enter Windows registration key to unblock" is virtually identical to a number of other scams of this type such as "Error XR01F5", "Error Code 09-986-6321", and "Windows Protected Your PC". The main goal is to trick visitors into contacting scammers who then try to convince people that they need to use their services or software (that must be purchased). Websites of this type should never be trusted. Do not use PUAs - they may seem legitimate and useful, however, they deliver none of the promoted functions. On the contrary, developers use them to generate revenue, which leads to a number of problems.
How did potentially unwanted applications install on my computer?
PUAs are usually installed through clicked intrusive ads or together with other (usually free) software. They are often bundled into the set-ups of other programs that people download/install intentionally. Developers hide information regarding the bundling of PUAs into set-ups - settings such as "Custom", "Advanced", and so on. If users leave these settings unchecked/unchanged, they often allow PUAs to be installed/downloaded with regular software that they wish to download and install.
How to avoid installation of potentially unwanted applications?
Download all software using official and trustworthy sources and websites. Do not use third party downloaders, installers, unofficial websites, and other dubious tools. Install/download software carefully. Check available "Custom", "Advanced" settings of the installation/download set-ups. Deselect any offers to install additionally-included, unwanted apps and only then finish the installation or download process. Note that not all advertisements can be trusted. Many dubious ads redirect to dubious, deceptive websites such as gambling, adult dating, pornography, and so on. If you continually experience unwanted redirects or intrusive ads,it is possible that unwanted apps are installed on your browser or operating system. Check the list of installed extensions, plug-ins, and add-ons on your browser, and programs on your computer. Remove unwanted, unknown software immediately. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
