Computer Tricks and Secrets

Short answer: Open an Incognito window in Chrome with Ctrl+Shift+N (Cmd+Shift+N on Mac) and it will not save your history, cookies, or form data once you close it. It is perfect for a shared or borrowed computer, but it does not make you anonymous online, so I pair it with a few extra settings. When you browse on a friend's PC or a cafe machine, the last thing you want is your history and passwords left behind. Chrome has a private browsing mode built for exactly this, and it is one of the simplest privacy wins there is. Here is how it works and where its limits are. How do I open Incognito mode in Chrome? There are two quick ways, and the keyboard shortcut is the one I use every time. Press Ctrl+Shift+N on Windows or Linux, or Cmd+Shift+N on Mac. Or click the three-dot menu at the top right of Chrome and choose New Incognito window . A dark window opens with a hat-and-glasses icon confirming you are private. Browse as normal, then close the window when you finish; ever...

Short answer: Chrome slows down mostly from too many tabs and extensions, a bloated cache, and low system memory, not from a secret setting. The genuine fixes are Chrome's built-in Memory and Energy Savers, ruthless tab and extension management, and keeping it updated. Here is exactly what works, and what is a myth. 1. Turn on Memory Saver and Energy Saver In Settings > Performance, enable Memory Saver (frees RAM from inactive tabs and reloads them when you return) and Energy Saver . Memory Saver is the single most effective built-in speed feature for people who keep many tabs open. 2. Audit your extensions Extensions are the most common hidden cause of a slow Chrome. Each one runs in the background. Go to chrome://extensions and remove anything you do not actively use. Use the built-in Task Manager (Shift + Esc) to see which extensions and tabs eat the most memory and CPU, then act on the worst offenders. 3. Manage tabs like they cost money Every open tab holds mem...

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: Google+ shut down years ago, but your Google account is now the hub of far more useful tools. The tricks worth knowing today are about controlling your data and privacy, securing the account, and getting more out of Search, Photos and Drive. Here are the ones I actually use. Take control of your data See everything Google has: My Activity shows your searches, watched videos and more, and lets you delete it or set auto-delete. Auto-delete history: set Web, Location and YouTube history to auto-delete after 3 or 18 months. Download your data: Google Takeout exports everything from any Google service. Secure your account Turn on 2-Step Verification , the single most important account safety step. Run the Security Check-up to review devices and app access. Remove old third-party apps that still have access to your account. Hidden-gem Google tools Tool What it does Google Lens Search or copy text from any photo Google Keep Quick notes synced everyw...

Short answer: to find your biggest Google Drive files, go to the storage-management page, which sorts everything by size in one click. But remember your 15 GB free quota is shared across Drive, Gmail and Google Photos, so the real space hogs are often huge email attachments and photos, not Drive files. Here is how to clear space fast. Step 1: Sort Drive files by size instantly Go to drive.google.com/drive/quota (the storage page). It lists your files sorted largest-first automatically. Review the top items, delete what you no longer need, and empty the Trash (deleted files still count until Trash is emptied). Step 2: Remember storage is shared across Google This is the part people miss. Your free 15 GB is split across three services: Service Common space hog Drive Large videos, old backups Gmail Emails with big attachments Photos Full-resolution photos and videos Step 3: Clear big Gmail attachments In Gmail, search has:attachment larger:10M to find emails with...

Short answer: If you are on Windows 11 you already have Chrome-style tabs built into File Explorer, no extra software needed; just press Ctrl+T. On Windows 10 or older, a free tool like QTTabBar adds tabs and a bookmark-style toolbar. The old Clover add-on is discontinued, so I no longer recommend it. Years ago I wrote about adding Chrome-like tabs to Windows Explorer using a tool called Clover. That tool has since been abandoned and can cause instability on modern Windows, so this is the updated, safe way to get the same experience. The goal is the same as it always was: one window, many tabs, faster switching between folders. Does Windows 11 have tabs in File Explorer? Yes, and this is the biggest change. Microsoft added native tabbed browsing to File Explorer, so you no longer need any third-party helper on Windows 11. In my daily setup I keep four or five tabs open constantly, one for Downloads, one for my current project, one for screenshots. Open File Explorer (Windows key...

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: Firefox usually slows down from too many extensions and tabs, a bloated profile, or hardware acceleration being off, not from a secret tweak. The genuine fixes are trimming extensions, managing tabs, keeping hardware acceleration on, clearing cache, and, if all else fails, the built-in Refresh Firefox. Here is what actually works. 1. Audit your extensions Extensions are the most common cause of a sluggish Firefox. Open the menu > Add-ons and themes, and remove anything you do not actively use. Each add-on runs in the background and adds up. Use Firefox's built-in Task Manager (type about:processes in the address bar) to see which extensions and tabs use the most memory and CPU. 2. Manage tabs Dozens of open tabs each hold memory. Close what you are done with, bookmark "read later" pages instead of keeping them open, and consider a tab-suspender extension only if it genuinely helps more than it costs. 3. Keep hardware acceleration on In Setting...

Short answer: before installing any recovery software, try the built-in options: the Recycle Bin, Windows File History and Previous Versions , and your cloud storage's version history. These often bring a file back with no extra tools. The key rule: the sooner you act (and the less you use the drive), the better your chances. Here is each method. 1. Check the Recycle Bin first The obvious one people skip in a panic: deleted files usually sit in the Recycle Bin. Open it, find the file, right-click > Restore , and it returns to its original location. (Shift+Delete or emptying the bin skips this, then you need the methods below.) 2. Restore with File History If File History was on (Settings > search "File History"), you can recover previous versions of files and folders: Open the folder that held the file. On the ribbon, choose History (or right-click the folder > Restore previous versions). Browse back to a time before deletion and restore the file. ...

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: WhatsApp does not store a separate contact list to export, it reads your phone's address book. So to "download your WhatsApp contacts," you back up your phone contacts to Google or iCloud, share individual contacts as vCards from within WhatsApp, and use WhatsApp's official Request Account Info to download your account data. I get asked this a lot, and the confusion is understandable. People assume WhatsApp keeps its own contact database. It does not. It matches your phone's address book against people who use WhatsApp. Once I explain that, the export options become obvious. Here are the legitimate, current ways to get your contacts out and safely backed up. Where do WhatsApp contacts actually live? Your WhatsApp contacts are simply the entries in your phone's address book that also have WhatsApp. That means the reliable way to "download" them is to back up and export your phone contacts, not to scrape WhatsApp itself. Get your pho...

Short answer: Export your Google Contacts to a CSV file, then import that file into Google My Maps. My Maps geocodes the postal addresses automatically and drops a pin for every contact, so you get an interactive map of where everyone lives or works in a few minutes. I keep hundreds of contacts in Google, and for years they were just a flat list of names. The moment I plotted them on a map, planning trips and meetups got dramatically easier. I could suddenly see which friends were clustered in one city and which addresses were worth a detour. Here is exactly how I do it, using only official Google tools that are free. Why map your contacts at all? A visual map answers questions a contact list never can. Who is near the conference I am flying to next month? Which clients are within a 30 minute drive of each other so I can batch visits? Where should I look for a place to stay when I visit a new region? Seeing addresses as pins instead of text turns your address book into a planning ...

Short answer: Facebook does not have a "reject" button that notifies the sender, it has Delete (or Ignore), which quietly removes the request without telling the person. If you keep getting unwanted requests, the real fix is to change who is allowed to send them. Here is exactly how it works and how to stop the flood. Delete does not mean reject When you tap Delete on a friend request, Facebook removes it from your list and the sender is not notified that you declined. To them, the request simply stays pending. They can send another later, which is why some requests feel like they will not go away. There is deliberately no confrontational "rejected" message. Why a request seems to come back If the same person keeps appearing, either they are re-sending, or you only removed it from your notifications, not the actual request. Go to your Friend Requests page directly and use Delete there. You can also mark a persistent, spammy request as spam. Stop unwanted...

Short answer: the free VLC media player you already use to watch videos can also convert them, change MKV to MP4, extract audio to MP3, and more, all offline and free, no extra software or sketchy converter sites needed. Here is how to use VLC's built-in Convert feature and keep good quality. How to convert a video in VLC Open VLC and go to Media > Convert / Save (Ctrl+R). Click Add and select your video file, then click Convert / Save . Choose a Profile (the output format), e.g. "Video, H.264 + MP3 (MP4)" for a widely-compatible MP4. Set the destination filename (add the correct extension like .mp4). Click Start . VLC converts the file; the progress shows on the playback bar. Common conversions Goal Profile to pick MKV to MP4 Video H.264 + MP3 (MP4) Extract audio to MP3 Audio - MP3 For a specific device A matching device profile Keep the quality up Click the wrench/edit icon next to the profile to adjust the bitrate and resolution. Higher b...

Short answer: you can make a Windows folder effectively invisible by giving it a blank name and a transparent icon, so it sits on your desktop with nothing showing. It is a fun trick for casual privacy, but remember it only hides the folder, it does not protect the contents. Here is how to do it and how to find it again. Step 1: Give the folder a blank name Right-click the folder > Rename . Delete the name, then hold Alt and type 0160 on the numeric keypad (this inserts an invisible character), then release Alt and press Enter. The folder now has no visible name. (The Alt+0160 code enters a non-breaking space, so Windows accepts the "blank" name.) Step 2: Give it a transparent icon Right-click the folder > Properties > Customize tab > Change Icon . Scroll through the icon list to find a blank/transparent icon (there are empty gaps among the icons), select it. Apply. Now both the name and icon are invisible, the folder is effectively hidden in p...

Short answer: to find when a web page was published, check the visible byline first, then dig into the page source or URL for a date, use a Google date filter, and confirm with the Wayback Machine, which shows when the page first appeared online. This matters for research, fact-checking, and judging whether information is current. Here is how. 1. Look for a visible date Many articles show a publish or "last updated" date near the title or byline. Start there, but be aware sites sometimes bump this date to look fresh without changing the content. 2. Check the page source Right-click and View Page Source, then search (Ctrl+F) for "datePublished", "dateModified", "published_time" or "date". Sites with proper structured data include the real publish and modified dates in the code, even when they are not shown on the page. 3. Use a Google date trick Search for the page, then use the Tools menu to filter by date, or check the small...

Short answer: You do not need cracked APKs to get paid Android apps for free. Watch for temporary price drops and giveaways, earn Play Store credit through Google Opinion Rewards, use free trials, and swap in free and open-source alternatives from F-Droid. Every method below is completely legal and keeps your phone safe. Let me be blunt about why I stopped chasing pirated apps years ago. Cracked APKs from random sites are the number one way people get malware, banking trojans, and hijacked accounts on Android. The irony is that with a little patience you can get almost any paid app for free or nearly free through official channels. Here is exactly how I do it. Can I get paid Play Store apps for free legitimately? Often, yes, because developers regularly make paid apps free for a limited time to boost visibility. The trick is knowing when. I use a price tracker so I never miss a drop. Use a price tracker like AppSales I keep a wishlist in a tracker such as AppSales . It monitors ...

Short answer: you can hide a file inside an ordinary JPG image on Windows with a one-line Command Prompt trick: zip your files, then combine the image and the ZIP into a single picture that opens normally but secretly contains your data. It is a fun, classic trick, but it is concealment, not encryption. Here is how it works and its limits. How to do it Put the files you want to hide into a ZIP archive (e.g. secret.zip). Pick a cover image, e.g. photo.jpg. Put both in the same folder. Open Command Prompt in that folder and run: copy /b photo.jpg + secret.zip output.jpg The output.jpg opens and displays as a normal image, but the ZIP is tucked inside it. How to open the hidden files Change the file extension of output.jpg to .zip, or open it directly with a ZIP tool like 7-Zip . 7-Zip (right-click > Open archive) reads the hidden ZIP straight from the .jpg, no renaming needed. Your hidden files are inside, extract them as normal. Why it works The copy /b comman...
