The script in the video comes from the creator himself and does one small job. That is exactly the kind of file you can verify with your own eyes before running it - if you know how to read it. This page teaches the two minute check that separates a handy shortcut from a blind risk, and it applies to every one click fix you will ever download.
In the video, the script is downloaded, run, and the lock screen ads vanish - job done, on camera. The standing rule in these guides is the safety step the camera leaves out: a script that runs with administrator rights can do anything on the PC, so read it before you run it. Registry and batch scripts are plain text files. That is not a weakness; it is your protection, because the file itself is a complete list of everything it will do. Here is how to read that list in about a minute, using this very script as the example.
A simplified example of the check, not a copy of the script. The real file is linked with the video - open that one, this way.
Download the script from the link given with the video, and if it arrives in a zip file, extract it first. Then right-click the file and choose Edit, or open Notepad and use File then Open. A .reg file opens in Notepad this way instead of merging into the registry; a .bat or .cmd file is just text waiting to be read. If what you downloaded turns out to be an .exe instead of a readable script, stop there - an executable cannot be read like this, and that difference is the whole point of the check.
For a lock screen job, expect a short file whose lines write values in the areas where Windows keeps these switches: the current user's content delivery and lock screen settings - the key family under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ContentDeliveryManager is where the suggestion and Spotlight-related user settings live - and possibly background or personalisation values to match. Read for proportion: a fix for one screen of settings should look like one screen of settings. Lines about your documents, your browser, your network, accounts or security software have no business in this file.
Close the file and delete it if you find any of these: commands that download something from the internet (words like DownloadString, Invoke-WebRequest or bitsadmin fetching a file), instructions that open hidden or minimised windows, anything creating scheduled tasks or startup entries, anything that disables Windows Security, the firewall or updates, and anything touching stored passwords or browser data. None of these can belong to a lock screen fix. Their presence means the file is either not what its name claims, or was tampered with after the creator shared it.
The tutorial page for this video lists the script's own download link. Use that one. Search engines and file-sharing sites collect files with names like 'disable lock screen ads fix' that wrap a few lines of honest script inside an installer full of junk - a classic way to smuggle adware onto office PCs. The size check helps: a text script for a job like this is tiny, a few kilobytes. If the download is large, arrives as an installer, or offers to add other software on the way through, it is not the file from the video, whatever its name says.
create a restore point in Start search and open itA restore point covers system and registry settings, which is exactly the territory a script like this works in. If anything behaves oddly afterwards, rolling back is a known, calm procedure. It does not protect your personal files - that is what backups are for - but for a settings script, it is the right-sized safety net.
Watch the video to see the script doing its one job on camera - then download it from the link with the video and give it the one minute read this page describes.
▶️ Watch Full VideoIt can be. Writing some policy and machine-wide settings needs elevation, and a script that prepares a PC for someone else may reasonably ask. It is also exactly why the Notepad check matters: admin rights plus unread text is the combination to avoid. Read first, and the rights request becomes an informed decision instead of a leap.
It means the file is not a readable text script - it may be encoded, compressed or an executable wearing a script's name. A genuine registry or batch script reads as plain text you can follow line by line. If you cannot read it, do not run it; get the text version from the creator's own link instead.
Open it now and read it - the file is still the complete list of what it did, and anything it changed can be identified and undone from that list. Then run a full scan with Windows Security for peace of mind. In the overwhelming majority of cases, including this video's script, what you will find in the file is exactly the settings it advertised.
