The reading list
Your photos, your accounts, your connection. Clear explanations for the technology you rely on.
Accounts & trust

Review recent Google Account sessions, understand duplicate entries and sign out of devices you no longer use.
Read the guideA website notification says your computer has a virus. Who sent it?
Identify the sender of a browser notification and block an unwanted site in Chrome without following its warning or installing a suggested cleaner.
Read the guideThe app is gone. Why is the subscription still renewing?
Find who bills your subscription, cancel renewal in the right account and check the confirmation before uninstalling the app.
Read the guideYou deleted the app. Can it still access your account?
Review connected apps, distinguish sign-in from data permissions and remove access you no longer need without losing a useful login.
Read the guideStill using Windows 10? Check the support, not just the update button
A working PC and a supported PC are different things. How to check your Windows edition, security coverage and next step in 2026.
Read the guideDoes that browser extension need access to every website?
A practical way to review extension permissions, narrow site access and remove tools you no longer use.
Read the guideBefore selling your phone, move the things that let you sign in
Photos are only part of a phone handover. Check account access, transfers and the manufacturer’s erase procedure before giving it away.
Read the guideRecovery codes are useful only if you can reach them
Where to keep account recovery codes, how they differ from passwords and what to check before losing access to your phone.
Read the guideAn email mask hides an address, not the whole account
Email aliases can help organise registrations and unwanted mail. They still depend on a working forwarding service and inbox.
Read the guideYour password export needs a short, careful journey
Moving passwords between managers can create a readable file. Plan where it goes, check the import and clean up unnecessary copies.
Read the guideA matching checksum is useful—but where did the checksum come from?
File hashes detect mismatches. Authenticating the published checksum answers a different question about the download’s origin.
Read the guidePasskeys are convenient. What happens if you lose your phone?
Before replacing a password, find out where your passkey lives and how you would sign in without your usual device.
Read the guideHTTPS protects the connection. Does it make a site trustworthy?
The browser can check a secure connection without vouching for every claim on the page.
Read the guidePhotos & storage
You saved over the right file. Can version history help?
Inspect an older OneDrive version, preserve the current file and restore deliberately without treating sync as a backup.
Read the guideShould your iPhone stop charging at 80 percent?
Understand the difference between a charge limit and Optimized Battery Charging, including why an iPhone may occasionally reach 100 percent anyway.
Read the guideA black rectangle does not necessarily remove text from a PDF
Use real PDF redaction, remove hidden information and inspect the saved copy before sharing. A visual cover is not proof of deletion.
Read the guideFind your BitLocker key before the laptop needs a repair
Check where your BitLocker recovery key is stored and whether you can reach it without the laptop. Your Windows PIN is not a replacement.
Read the guideA shared cloud file needs an exit plan
How to choose access for a shared document, review who can open it and close access after the task is finished.
Read the guideWhy one USB-C cable charges your laptop but will not run the display
The connector shape does not specify every capability. Match power, data and video requirements across the whole connection.
Read the guideFree disk space by identifying files, not guessing from their size
A careful cleanup starts with storage categories and recoverable copies. Large folders are not automatically disposable.
Read the guideSaving a JPEG as PNG will not bring back lost detail
Choose image formats according to the original and the next use. A larger file is not necessarily a better image.
Read the guideBefore going offline, open the files with the connection off
A filename in a cloud folder does not guarantee the contents are on the device. Prepare and test the files you will need away from the network.
Read the guideYour cloud folder is in sync. Is it also backed up?
A deletion can travel just as efficiently as a new file. The difference matters when you need an earlier version.
Read the guideKeep a photo archive you can open without your cloud account
An independent export protects more than the pictures. It gives you a way to check what you actually have.
Read the guideA home NAS or cloud storage: choose the chores as well as the space
The useful comparison includes maintenance, recovery and how you reach your files—not just terabytes.
Read the guideThe backup finished. Now try restoring one file.
A small recovery rehearsal can expose missing passwords, unreadable files and the wrong version—before an emergency.

Wi-Fi 6E is on the router box. Will your device use 6 GHz?
Check router and client support, network naming and the actual connection before expecting the 6 GHz band.
Read the guideUsing a phone hotspot? Tell Windows the connection is metered
Mark a phone hotspot as metered in Windows 11, review background transfers and check usage. The setting reduces traffic rather than imposing a hard cap.
Read the guideA mesh point also needs a good connection back to the router
Ethernet backhaul can help a mesh network, but compatibility, wiring layout and a simple comparison matter more than adding another point.
Read the guideWhy a photo upload can spoil a video call
A connection can have good download speed and still become unresponsive under load. Compare latency during an upload before changing your equipment.
Read the guideIPv6 is another network path to understand, not a switch to fear
A home network may use IPv4 and IPv6 together. Keep security and troubleshooting checks consistent across both.
Read the guideYour router can keep working after its security support ends
Check the exact model, hardware revision and update policy before assuming that a stable connection means the router is still maintained.
Read the guideWhy a website can feel slow on a fast internet connection
A speed test measures one part of the journey. A page still has to wait, download and become usable.
Read the guideFull Wi-Fi bars, broken video call: what to check first
The signal indicator tells you about one connection. A call depends on the rest of the path too.
Read the guideYou moved a website. Why do some visitors still see the old one?
DNS caching explains part of the delay, but browser and content caches can create a similar symptom.

The AI formula looks right. Test it on five rows first
Build a tiny spreadsheet with known answers and test blanks, zeros, dates, units and range boundaries before trusting an AI-generated formula.

Separate information requests from actions in connected apps, check Gemini’s supported operations and verify the result in the calendar itself.
Read the guideA document gives instructions to the AI. Should the assistant follow them?
Recognise when source material tries to change the task, keep quoted instructions separate from your request and check unexpected actions.
Read the guideDeleting an AI chat: what happens to memory and connected data?
Use Gemini as a concrete example to separate chat deletion, memory settings, connected apps and public sharing links.
Read the guide“On-device AI” is a starting point for a privacy check
A feature can combine local processing and online services. Check the particular task, data sent and settings rather than relying on one label.
Read the guideBefore asking AI about a PDF, check what it can actually read
Scanned pages, tables and faint digits can change what reaches an AI tool. A few checks make document questions easier to verify.
Read the guideThe most useful part of a document may be what the AI summary leaves out
Short summaries can lose conditions, exceptions and uncertainty. Ask for those explicitly and compare them with the original.
Read the guideContent Credentials describe a file’s history, not the whole truth
What provenance information can tell you about an image, why missing credentials prove little and where ordinary verification still matters.
Read the guideAn AI answer has citations. Do they support what it says?
A short checking routine for confident explanations, impressive links and claims that may have changed.
