Windows Dynamic lock uses a paired phone's Bluetooth signal to lock a PC when you leave. Pairing, range and a practical test matter; it does not replace Windows+L or automatically unlock the computer on return.
A phone left charging beside the laptop cannot tell Windows that you have walked away. Windows Dynamic lock depends on the paired phone leaving Bluetooth range. That makes a short practical test more useful than simply enabling the switch and assuming the desk is protected.
Pair the intended phone, enable Dynamic lock in Accounts and Sign-in options, then take the phone away and check that the PC locks. Windows describes locking within a minute after the phone leaves Bluetooth range. Press Windows+L for an immediate manual lock. There is no need to replace a keyboard for this setting; a Logitech K120 listed at R129 on 13 October 2026 is a separate hardware purchase.
Start by checking Bluetooth pairing on the PC and phone. Make sure you recognise the device name, especially if several family phones have connected to the computer. A remembered entry is not the same as proof that the intended phone is present and usable for this test.
Open Settings, Accounts and Sign-in options, then locate Dynamic lock. If the computer belongs to an organisation, its settings can be controlled by policy. Ask the administrator when the option is unavailable. Changing unrelated account settings adds uncertainty without establishing that the Bluetooth condition is working.
Save current work and run the test at a time when a locked screen will not interrupt a call. Take the phone with you and move beyond the connection's normal range. Return and inspect the PC. The result you need is an actual locked session, not just a disconnected phone icon.
Repeat this in the places where you normally leave the desk. Radio range varies with the room and equipment, so do not describe the feature as a fixed number of metres. If the phone stays near the computer, automatic departure detection cannot represent your own movement. That is particularly relevant when it remains on a desk charger.
Windows+L provides an immediate deliberate action. Use it before leaving a shared desk or a screen containing private work. Dynamic lock is useful as an additional automatic behaviour, but its detection delay makes it a poor substitute for that habit when the lock needs to happen now.
The feature also does not provide automatic sign-in when you return. Choose an appropriate supported sign-in method separately. Avoid interpreting a successful lock test as evidence that every account or security setting is configured correctly; it establishes only the departure behaviour being tested.
If Bluetooth itself is missing or unreliable, identify that problem before browsing keyboards on special. A R129 keyboard cannot supply the phone-pairing function. Keep the accessory budget separate from the diagnosis so a security setting does not become an unnecessary replacement.
For a new desktop build, all intel motherboards can be compared for the connectivity actually required, including the exact wireless provision. Check the complete product specification rather than infer Bluetooth from a familiar chipset name. On an existing PC, record the pairing result and lock test first; that evidence gives support a specific failure to investigate.
The documented feature relies on a Bluetooth-paired phone. Set up the intended device before testing departure.
Not necessarily. Bluetooth range and detection take time. Test the behaviour in your own room rather than assuming a fixed distance.
Dynamic lock is an automatic locking feature. Returning with the phone is not an automatic sign-in method.
Press Windows+L when leaving the desk. Use it when an immediate lock matters, even if Dynamic lock is enabled.
No. Dynamic lock depends on pairing and settings. A Logitech K120 was R129 on 13 October, but buying it does not fix a Bluetooth issue.
Ask the device administrator about the policy. Do not work around an organisation's sign-in controls.
Prove the lock before relying on it. Pair the intended phone, test departure and keep Windows+L as your immediate desk-leaving habit.

Windows Delivery Optimisation can share update files with other PCs. Review its activity, choose local-only sharing or turn peer sharing off, and use bandwidth controls; those choices do not disable Windows Update.

Windows touch indicator adds visual feedback where you touch a screen. Change it in Accessibility, Mouse pointer and touch; a feedback circle is different from inaccurate input, ghost touches or a damaged panel.

Windows underline access keys makes supported menu letters easier to see. Enable the keyboard accessibility option, then follow the app's displayed Alt cues; this does not remap keys or create missing app shortcuts.

Windows notification duration controls how long supported banners stay visible. Adjust the dismissal time in Accessibility, Visual effects, then test a real alert; app permissions and Do not disturb remain separate settings.

Windows flash screen options provide visual feedback for audio notifications. Check Accessibility, Audio when flashes track alerts; random flicker, signal loss and panel faults need a separate diagnosis.

RTX 5090 should be enough for Palworld at 1080p when the rest of the PC is balanced. Use this SA-focused guide to weigh settings, monitor refresh, CPU balance, and upgrade room without relying on unsupported FPS claims.
A second-hand GPU on a R5,000 SA budget can save money but adds condition risk. Check warranty, temperatures, fan noise, ports, seller proof, power draw, and return options first.
student laptop guide for Gqeberha gamers should be shortlisted around the job it must do. South African buyers should compare CPU, GPU, RAM, and screen quality, warranty path, and upgrade room before treating any pick as best.
Recommended build for Expedition 33 at R40 000 gives SA buyers premium 1440p headroom and selective 4K potential. Spend on the GPU, CPU balance, cooling, NVMe storage, power quality, and the right display pairing.
Windows transparency effects can be switched off to make supported backgrounds more opaque. Use Accessibility, Visual effects or the colour settings, then compare a menu against your wallpaper. This R0 preference changes appearance; it is not a promised.
Windows title bar window shake can minimise other open windows when you shake the active window by its title bar. Inspect the Multitasking setting and switch it off if that gesture interrupts your work. The preference costs R0 and does not require new hardware.
Windows Print Screen opens Snipping Tool when its keyboard preference is enabled. Change the option under Accessibility, Keyboard to choose another workflow. Test whether you need a clipboard image or a saved file.
Windows desktop icons missing may be a visibility setting. Right-click the desktop, choose View and inspect Show desktop icons. If only system icons are absent, use Desktop icon settings. Check the Desktop folder before assuming files were deleted.
Intel Core Ultra can look weaker in Roodepoort gaming benchmarks when tests are GPU-limited or tuned poorly. Check power settings, drivers, memory, game mix, and cooling before judging CPU value for an SA gaming PC.
RTX 5090 alternatives make more sense for office and study PCs in South Africa when the goal is smooth screens, quiet use, and sensible cost. Focus on display support, reliability, power use, desk space, and whole-system balance first for SA buyers.
Spider-Man 2 low FPS on RTX 5070 needs settings, driver, power, and background-load checks. For SA players, check updates, verify files, test overlays, reset graphics options, and keep changes reversible before reinstalling.
An RTX 4080 alternative can prioritise competitive shooters speed over excess. Compare high refresh, low latency, CPU balance, ZAR value, and monitor upgrade room before buying for a South African esports setup.
