For personal devices, enable automatic updates, install security notifications promptly—ideally within a few days—and occasionally check that installation finished. If a vendor or security agency warns that a vulnerability is being actively exploited, do not wait for a weekly or monthly check: install the fix as soon as feasible. There is no single calendar schedule that fits every program, because vendors release updates at different times.
Is there a set schedule for updating software?
No. A weekly or monthly check is not a substitute for installing an urgent security fix when it becomes available. A safer routine is to let supported software update automatically where possible, respond promptly to update notices, and verify from time to time that updates succeeded.
That advice follows the release schedule of each product rather than an arbitrary calendar. The UK National Cyber Security Centre (NCSC) says, “Apply updates as soon as possible, and ideally automatically, in line with our best-practice timescales.” The U.S. Cybersecurity and Infrastructure Security Agency (CISA) similarly advises installing updates as soon as possible to protect devices against attackers exploiting vulnerabilities. See the NCSC’s policy to update by default and CISA’s Understanding Patches and Software Updates.

Apply the same principle to the operating system and the programs that handle everyday data or connect to the internet. That includes browsers, office applications, document and PDF readers, email clients, and security software, as well as the operating system on a phone, tablet, laptop, or desktop. Routers and other managed devices also need the vendor’s firmware process followed when updates are offered.
#1 Best Overall
Automatic updating is useful because different vendors publish fixes on different timetables. One application may update in the background while another waits for a restart or a user confirmation. A single monthly reminder can therefore leave a newly released fix unapplied for weeks. Keep an inventory of important programs, but use it to confirm completion rather than to postpone updates until a particular day.
How quickly should I install updates on a personal device?
For a phone, tablet, laptop, or desktop, install an available security update promptly—ideally within a few days—and restart if prompted. The NCSC’s consumer guidance does not set a universal number of hours or a recurring weekly deadline; it recommends acting promptly and checking occasionally that updates actually applied.
Set up automatic updates
Leave automatic updating enabled for the operating system, browser, office applications, document readers, and security software when the vendor offers that setting. CISA and the NCSC both recommend automatic updating where possible. This reduces dependence on remembering to check for every product, but it does not remove the need to notice whether an update has completed.
Respond to a notification
When a security update notice appears, install it as soon as practical rather than saving it for a routine maintenance day. If the notice requests a restart, complete it so the update process can finish. The NCSC’s device and software guidance recommends applying updates as soon as possible, ideally automatically, and says personal-device users should install prompts ideally within a few days.
Verify that updates worked
Check occasionally that the device or application reports as up to date. An automatic process can stall if the device lacks Wi-Fi, power, or free storage, or is waiting for a restart. If an update appears stuck, address the indicated requirement and check again; do not assume that enabling automatic updates proves the patch installed.

A practical routine for home users
- Turn on the vendor’s automatic-update setting. Use the operating system and each major application’s own settings rather than an unrelated updater.
- Read the notice. Distinguish a security update from an optional feature change, but do not ignore a notice that identifies a security fix.
- Choose a safe installation moment. Connect a laptop or phone to power, use a trusted Wi-Fi connection, close work that must be saved, and allow enough free storage.
- Restart when requested. A download may finish without the device actually applying the update until it reboots.
- Confirm the status. Look at the update page or application version after installation. If it still shows pending, resolve the stated problem and try again.
- Keep a current backup. Back up important files before a major update, especially when the device contains irreplaceable photos or documents. The backup is a precaution, not a reason to defer a security fix.
These steps address common reasons an automatic process does not finish. They also provide a simple check for a household with several devices: review update status occasionally instead of assuming every device succeeded silently.
When should I update immediately?
Do not wait for your next routine check when a critical security alert or known exploitation changes the urgency. Install the fix as soon as feasible and follow the vendor’s or incident responder’s instructions. The NCSC warns that ordinary vulnerability-management timelines are too long when a vulnerability is being exploited at scale; its business-as-usual targets should not be used to justify delaying an urgent fix.
Recommended Free Tools
This is especially important for organizations with internet-facing services or legacy systems, which the NCSC identifies as priorities. CISA’s business software update guidance also emphasizes keeping business software updated. The NCSC’s manufacturer guidance covers the importance of providing updates securely: Device security principles for manufacturers: Provide updates securely (version 2.1, reviewed 13 May 2025).
An urgent notice can arrive outside a planned maintenance window. For a personal device, install as soon as you can use a trusted connection and power source. For a business, record the alert, identify affected assets, and shorten the normal test-and-rollout path where the threat requires it. Do not interpret a five-, seven-, or fourteen-day business target as permission to wait that long for an actively exploited flaw.
What update deadlines should organizations use?
Organizations need a managed patch process with rollout controls and completion deadlines. The NCSC’s business-as-usual vulnerability-management guidance gives the following targets by estate type; they are organizational operational targets, not a universal home-user schedule.
| System or service | NCSC business-as-usual completion target | Practical implication |
|---|---|---|
| Internet-facing services and software | Within 5 days | Prioritize exposed systems in testing and rollout. |
| Operating systems and applications | Within 7 days | Apply automatically where possible and track completion across the estate. |
| Internal or air-gapped services and software | Within 14 days | Test and roll out according to the system’s role. |
These targets come from the NCSC’s organizational policy to update by default, accessed in 2026. They are completion targets for business-as-usual vulnerability management, not measurements of how much risk is reduced. The guidance recognizes testing and controlled rollout for business-critical systems, while calling for acceleration when exploitation is widespread. In other words, use testing to manage operational consequences, not as an open-ended reason to postpone a critical security fix.

Maintain an asset list showing which operating systems, applications, internet-facing services, and legacy products an organization uses. When a patch arrives, assess exposure and business role, test it on a representative small group or test environment where practical, then deploy in stages and monitor completion. Internet-facing systems receive the shortest normal target because they are reachable by attackers; internal or air-gapped systems have a longer fourteen-day business-as-usual target.
Document exceptions, owners, and a new deadline when a system cannot be updated immediately. An exception should have a reason and compensating plan, not simply remain open. If the vulnerability is being exploited at scale, reassess the normal test window and accelerate deployment in line with the NCSC warning.
How can I make updates safer without delaying them?
Use trusted update channels and prepare appropriately for larger changes. CISA cautions against relying on unsolicited email or advertising links for updates. Get updates through the device’s built-in update mechanism or the software vendor, and back up important data before a major update.
- Keep automatic updates enabled. Use the setting supplied by the operating system or application vendor when available.
- Use a trusted route. Open the device’s built-in update settings or go directly to the vendor’s update channel; do not follow unsolicited links in email or ads.
- Back up important data before a major update. Treat a current backup as a prudent precaution, not as a reason to leave a security fix pending.
- For a managed estate, test and stage broad rollouts where appropriate. NCSC business guidance recognizes testing and controlled deployment, particularly for business-critical systems. When exploitation is active, reassess the normal rollout and accelerate.
- Confirm completion. Check update status, resolve requirements such as power, Wi-Fi, storage, or restart, and verify again.
Common mistakes to avoid
- Waiting for a weekly “update day” even after an urgent security warning.
- Assuming a download completed means the patch is active when a restart is still required.
- Using an unsolicited email or advertisement link instead of the built-in updater or vendor site.
- Letting a failed update remain unresolved because automatic updates are enabled.
- Keeping an unsupported application installed and believing antivirus or a paid updater can supply the missing vendor fix.
What if my software no longer receives security updates?
A routine update check cannot protect software for which the vendor has stopped supplying security fixes. Track support end dates and plan to replace or retire unsupported software or devices. CISA and the NCSC treat end of support as a separate security problem, not something solved by installing updates more often.

This applies to both applications and devices. If the product is still in support but updates are failing, resolve the installation issue; if support has ended, identify a supported replacement or retire the product. The NCSC’s keeping devices and software up to date guidance and CISA’s business software guidance support maintaining updated, supported products.
Check support status when buying or deploying equipment, not only when an update fails. A replacement supported device is the appropriate remedy when security updates have ended; installing another updater cannot extend the vendor’s support period.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How much does an update schedule reduce security risk?
The cited official guidance gives practical update recommendations and organizational completion targets, but it does not establish a defensible percentage reduction in risk for a particular personal update schedule. The five-, seven-, and fourteen-day targets are operational deadlines, not risk-reduction statistics. It would be misleading to promise that a particular cadence makes a device a stated percentage safer.
The useful decision is therefore not to seek a magic interval. Keep automatic updates on, install prompts quickly, verify completion, respond faster to urgent exploitation, and replace products after security support ends.
Frequently Asked Questions
Do I need to update an app if I rarely use it?
The official guidance applies to software and devices that need to remain updated, not only to frequently opened programs. If you no longer need an application, retiring it avoids relying on an update routine for software you do not use.
Can antivirus replace software security updates?
No. CISA and the NCSC recommend vendor-provided updates and supported products; antivirus is not a substitute for a security fix or ongoing vendor support.
Why do business deadlines differ from advice for home devices?
Organizations manage estates with different exposure and operational roles, so the NCSC specifies rollout targets by system type and recognizes testing. Those organizational targets are not a recommended waiting period for an individual facing an urgent alert.
Is installing updates every month enough?
No. A monthly check can miss a fix released today. Enable automatic updates and install security prompts promptly, ideally within a few days; act as soon as feasible when exploitation is reported.
What if an update keeps failing?
Check the device’s message for requirements such as power, Wi-Fi, free storage, or a restart, correct the problem, and verify the status again. If the product is still supported and cannot update, contact the vendor or administrator; if support has ended, replace or retire it.
Should I postpone an update to avoid disrupting work?
For business-critical systems, organizations can test and stage a rollout to manage operational consequences. That is controlled deployment, not indefinite delay. When a vulnerability is actively exploited, shorten the process and follow the vendor or incident responder’s instructions.
Are updates from an email link safe?
Use the device’s built-in update mechanism or the software vendor’s trusted channel. CISA cautions against relying on unsolicited email or advertising links, which may be fraudulent.
What should I do before a major update?
Back up important data, connect the device to power, use a trusted connection, ensure sufficient storage, and allow time for a restart. Keep the backup as a precaution while still installing the security fix promptly.
