Computer Tricks and Secrets

Short answer: Go to haveibeenpwned.com , type in your email address, and it tells you which known data breaches included your details. If you show up in any breach, change that password everywhere you reused it and switch on two-factor authentication today. I have lost count of how many times a friend has messaged me in a panic asking "is my email hacked?" after seeing a weird login alert. The honest truth is that most people have some data floating around from an old breach, and that is fine as long as you react properly. In this guide I walk through the exact checks I run and the cleanup I do afterwards. What "hacked" usually means When I say an account was compromised, I normally mean one of two things. Either your password leaked in a bulk data breach of a website you used, or someone guessed or phished it directly. The first case is far more common. Companies get breached, the stolen username and password lists get traded online, and attackers try those sa...

Short answer: if a PDF asks for a password every time you open it and you know that password, you can remove it for free in a minute, no cracked "password remover" needed. The simplest method is to open it in Chrome with the password, then print it back to a new PDF. Here are the free ways, and an honest note on what this can and cannot do. Important: this is for PDFs you own These methods remove a password you already know from your own documents, for convenience. They do not "crack" a password you do not have, and you should not try to bypass protection on files you have no right to. Removing protection you legitimately possess is fine; defeating someone else's is not. Cracked "password remover" tools that claim to break unknown passwords are both dubious and a malware risk. Method 1: Chrome print-to-PDF (easiest, free) Open the PDF in Google Chrome and enter its password. Press Ctrl+P (Cmd+P on Mac) to print. Choose Save as PDF as the de...

Short answer: a cracked anti-keylogger is the most likely place to find a keylogger, so skip it. Real protection comes from built-in security plus a few habits, and two-factor authentication that makes a stolen password useless. Here is how keyloggers work and exactly how I defend against them. What a keylogger is and how it arrives A keylogger records what you type, aiming to capture passwords and card numbers. The vast majority arrive bundled with pirated software, cracks, and keygens, which is why this post used to be part of the problem. Avoiding cracked software removes your single biggest risk. Layer 1: keep Microsoft Defender on Microsoft Defender on Windows 10 and 11 detects and blocks common keyloggers automatically. Keeping it enabled and updated covers most threats without any extra software. Layer 2: two-factor authentication (the key defense) This is the non-obvious one. Even if a keylogger captures your password, two-factor authentication (2FA) means the attack...

Short answer: If your PC uses a Microsoft account, reset the password online at account.live.com/password/reset from your phone and sign back in. If it uses a local account, use your password reset disk or the security questions on the lock screen. This guide is only for regaining access to a computer that belongs to you. A quick but important note before anything else: everything below is for your own machine, or one you have clear permission to fix. Bypassing a password on someone else's computer is a different thing entirely and I do not cover that. With that said, I have been locked out of my own laptop more than once, and here is exactly how I get back in without wiping my files. First, work out which account type you have Modern Windows 10 and Windows 11 sign-ins come in two flavours, and the fix is completely different for each. Microsoft account : you log in with an email address (Outlook, Hotmail, or similar). This is the easy case. Local account , a username tha...

Short answer: no, you cannot legitimately view someone's private Facebook photos, and every tool or "app" that claims to is a scam, a phishing trap, or malware. Private means private by design. What you can do is make sure your own photos are properly locked down. Here is the honest explanation and how to protect yourself. Why the "view private photos" tricks are fake Old posts pointed to Facebook "apps" or browser add-ons that promised to reveal private photos. They never worked, because Facebook's servers simply do not serve private content to people without permission. What those tools actually did was: Phish your login, stealing your own account in the process. Spam your friends or post on your behalf once you granted the app access. Install malware or bombard you with ads. The person seeking to snoop ends up being the victim. That is the pattern with every one of these. Trying to access someone's private content is also wro...

Short answer: you can find clues about an email sender's origin in Gmail by viewing the full email headers ("Show original"), which reveal the sending servers and sometimes an originating IP address you can look up for an approximate location. It is useful for spotting scams, but it only gives a rough, often server-level location, not the sender's home address. Here is how, and what it can and cannot tell you. How to view the full headers Open the email in Gmail. Click the three-dot menu (More) at the top right of the message. Choose Show original . A new tab shows the raw email with all headers: From, Received (the server hops), SPF/DKIM results, and more. What the headers tell you Received lines: trace the path the email took through mail servers, read from bottom to top for the origin. Originating IP: sometimes present near the earliest Received line; you can look it up in an IP geolocation tool for an approximate region. SPF/DKIM/DMARC: whether...

Short answer: to do a privacy check, look at yourself the way a stranger would, search your own name, use each platform's "View As public" tool, and check what shows up. You will usually find more exposed than you expected. Here is a step-by-step self-audit and how to lock down what you find. Step 1: Search yourself Search your full name (in quotes), plus your name with your city, school or employer, in Google and an image search. Do it in a private/incognito window so your own login does not skew results. Note every profile, photo, phone number or address that appears, that is what strangers see. Step 2: Use "View As Public" on your profiles Facebook: profile > three dots > View As to see your profile as the public does. Instagram / others: check whether your account is public and what a non-follower can see. LinkedIn: view your public profile and adjust what is visible. Anything you would not hand to a stranger, lock down. Step 3: Do a...

Short answer: the safest way to unblock a website is a reputable VPN, which encrypts your traffic and routes it through another location, bypassing most blocks while protecting your privacy. Changing your DNS also helps for simple blocks. But respect the rules of networks you do not own, and avoid sketchy free proxies. Here is how, safely. First, a word on rules and safety Bypassing blocks on a network you do not control (a school or workplace) may violate its policies, know the rules before you do. And whatever method you use, avoid random free "web proxy" sites: many log your data, inject ads, or steal credentials. Use reputable tools. Method 1: A reputable VPN (best and safest) A VPN encrypts all your traffic and sends it through a server elsewhere, so the local network cannot see or block the sites you visit, and your data stays private. Choose a well-reviewed paid VPN (free ones often log or sell data). This is the most reliable method and it protects you, not ju...

Short answer: a popular Notepad batch script can hide and "lock" a folder behind a password for casual privacy. It is a fun trick that stops a nosy sibling or coworker, but it is NOT real security, the files are recoverable. For anything genuinely private, use encryption. Here is the trick and, more importantly, the safe alternative. The Notepad folder-lock script Open Notepad and paste this script (change YOURPASSWORD to your own): cls @ECHO OFF title Folder Locker if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK if NOT EXIST Locker goto MDLOCKER :CONFIRM echo Lock the folder? (Y/N) set/p "cho=>" if %cho%==Y goto LOCK if %cho%==N goto END :LOCK ren Locker "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" echo Folder locked goto End :UNLOCK echo Enter password to unlock set/p "pass=>" if NOT %pass%==YOURPASSWORD g...

Short answer: the fastest way to lock Windows is the keyboard shortcut Windows key + L , it locks instantly, requiring your password/PIN to get back in.

Double-click it anytime to lock; you can even pin it to the taskbar. Auto-lock when you step away Method How Screen timeout + lock Settings > Accounts...

Short answer: you can hide a drive in Windows so it stops appearing in File Explorer, either by removing its drive letter in Disk Management, or via a Group Policy / registry setting. It is a quick way to keep a drive out of sight, though it is light privacy, not real security. Here is how, and how to still access the hidden drive. Method 1: Remove the drive letter (Disk Management) Right-click the Start button and open Disk Management . Right-click the drive you want to hide and choose Change Drive Letter and Paths . Select the letter and click Remove . The drive disappears from File Explorer (its data is untouched). To bring it back, repeat and Add a drive letter again. Method 2: Hide via Group Policy or registry On Windows Pro, the Group Policy Editor (gpedit.msc) has a "Hide these specified drives in My Computer" option under User Configuration > Administrative Templates > Windows Components > File Explorer. On Home editions, a registry value (NoDr...

Short answer: there are three levels of hiding a folder in Windows: the invisible-folder trick (blank name + transparent icon) for a quick disguise, the hidden attribute for keeping it out of normal view, and real encryption for actual protection. Pick based on how sensitive the contents are. Here are all three and when to use each. Level 1: The invisible-folder trick (quick disguise) Make a folder blend into the desktop: Rename it: delete the name, hold Alt and type 0160 (a blank character), press Enter. Right-click > Properties > Customize > Change Icon, and pick a blank/transparent icon. Now it has no visible name or icon. Good for a casual "hide in plain sight", but easily found by selecting all on the desktop. Level 2: The hidden attribute Mark a folder as hidden so it does not show in normal browsing: Right-click the folder > Properties > General tab. Tick Hidden , then Apply. It disappears unless someone turns on "Show hidden fil...

Short answer: you can safely test your antivirus with the official EICAR test file, a harmless string that every real antivirus is designed to detect as if it were a virus. If your antivirus instantly flags it, protection is working. If nothing happens, your antivirus is off, misconfigured, or not scanning properly. Here is how to run the test safely. What the EICAR test file is The EICAR test file is an industry-standard, completely harmless piece of text created specifically so people can test antivirus software without any real malware. It does nothing to your computer, but every legitimate antivirus recognizes it and reacts as though it found a threat. It is the safe, standard way to confirm your protection is active. How to run the test Open Notepad . Paste the official EICAR test string (a single line of text) that you can copy from the official EICAR website . It begins with X5O and is documented there. Try to save it as eicar.com or fakevirus.txt . A working antiv...

Short answer: keeping Android updated matters mostly for security , updates patch flaws that attackers exploit, and secondarily for features and stability. Check for updates in Settings > System > System update. When your phone stops getting official updates, you can extend its life with a custom ROM or repurpose it. Here is the full picture. (Old version-specific guides age fast; this is the evergreen version.) Why updates matter Security: monthly patches fix vulnerabilities. An unpatched phone is a real risk for banking and personal data. Features: new Android versions add genuine improvements to privacy controls, notifications and battery. Stability and app support: updates fix bugs, and some apps eventually require a newer Android version. How to check for and install updates Go to Settings > System > System update (wording varies by brand). Tap Check for updates and install anything available. Also update Google Play system updates and Google Play ...

Short answer: XMODGames was a mid-2010s mobile game-modding tool that is now dead, and I strongly advise against the APKs floating around today. They are usually repackaged with adware or root exploits, and they will get your game account banned. I stick to legitimate options like private servers and image-based automation instead. If you were into mobile gaming back in the mid-2010s, you almost certainly ran across Xmodgames. It was one of the most popular game-modding tools for Android and iOS, letting players overlay custom UI features, automate tapping, and run sandboxed tests on games like Clash of Clans, Subway Surfers, and 8 Ball Pool. After years of poking at gaming utilities, I have watched this whole category rise and then collapse, so here is the honest story. The rise and fall of XMODGames Xmodgames ran on rooted devices and injected helper files directly into the active game memory while the app was running. For sandbox testing, such as trying attack layouts in Clash of C...

Short answer: before I trust a new Windows PC with real work I do seven things in order: fully update Windows, install my own browser, sort out security, strip the bloatware, install my core apps in one pass, make a full backup image, and only then touch drivers. The backup image is the step almost everyone skips and later regrets, so do not skip it. 1. Update Windows until it stops finding updates Settings > Update and Security > Windows Update. Install, reboot, and repeat until it comes back empty. A PC that sat in a warehouse for months can need several rounds. I never browse the web on an unpatched machine. 2. Install the browser I actually use I do not live in whatever shipped by default. Direct links: Chrome , Firefox , Opera . 3. Sort out security (usually by removing things) Modern Windows ships with Microsoft Defender, which is good enough for most people. The catch is that PC makers often preinstall a trial of Norton or McAfee that disables Defender. So...
