The most time-consuming ticket in most queues isn’t a hardware failure. It’s the PC infection that started when a user installed something they shouldn’t have been able to. Or the broken configuration left behind after someone changed a setting nobody can trace.
Local administrator rights, the ability to install software, modify system settings, and override security controls, get handed out to end users far more often than the risk warrants. The usual reason is efficiency. The practical result is the opposite: machines drift from baseline, infections spread before they’re caught, and remediation tickets pile up that nobody planned for.
Revoking local admin rights directly removes the root cause of most of those tickets, and tightens endpoint security in the same change.
What the data says
The connection between admin rights and security incidents is well-documented.
The BeyondTrust Microsoft Vulnerabilities Report has consistently found that removing administrative privileges would mitigate 75% of all Critical Microsoft vulnerabilities. Most critical vulnerabilities require elevated permissions to fully execute. An attacker who compromises a standard user account gets that user’s data and session. An attacker who compromises an admin account gets the machine, and often the network behind it.
IBM’s 2025 Cost of a Data Breach Report puts the global average breach cost at a record high. The remediation cost for breaches that start through compromised endpoints is consistently higher when the affected user holds elevated privileges. Revoking local admin rights doesn’t eliminate the risk, but it significantly reduces what an attacker or an infected machine can actually do.
The three ticket categories that disappear
- Malware infections and their cleanup.
Most ransomware and many Trojans require admin-level permissions to install, disable security tools, and spread. A standard user account doesn’t eliminate phishing risk, but it limits what malware can do after it lands. An infection on a standard account is typically contained to one user’s profile. On an admin account, the same infection can encrypt shared drives and require a full OS rebuild. A contained event might be one ticket and thirty minutes. An admin-level infection often runs to several tickets and several hours. - Self-inflicted configuration breaks.
Users with admin rights occasionally try to fix their own problems by changing settings, uninstalling software, or modifying network configurations. When it goes wrong, IT inherits the result with little visibility into what changed. Standard accounts remove this category almost entirely, because those changes are no longer possible without an elevation request. - Patch and compliance drift.
Endpoints where users have admin rights tend to diverge from the managed baseline over time. Software installed outside the approved process doesn’t pick up updates through standard management tools. Devices accumulate inconsistencies that show up later during vulnerability scans and audits. Revoking admin rights and enforcing managed software deployment closes the drift at the source.
“But I need to install things”
The concern is legitimate. Users do occasionally need elevated access for a specific task. The answer isn’t permanent admin rights. It’s just-in-time (JIT) elevation.
JIT gives a user temporary elevated access for a defined task. The request is approved through an automated policy or by IT, and the elevation expires automatically once the task is done. Every elevation is logged. Unapproved actions don’t happen silently.
The volume and pattern of requests becomes useful data in its own right. After a few weeks of JIT, you can see exactly which tasks genuinely need elevation and which ones users were doing only because nothing was stopping them.
Standard accounts support normal application use, browser activity, printing, file access, and the great majority of day-to-day tasks without any escalation at all. The friction people anticipate is usually larger than the friction they actually experience once JIT handles the edge cases.
How to roll this out
A least-privilege rollout isn’t dramatic. It’s incremental.
Start with a small group, often the partners and senior managers who have the broadest access today. Run JIT alongside the change so they have a quick path to elevation when they genuinely need it. Communicate the change a week in advance, explain why, and provide the JIT request process in writing.
Expand from there in waves. By the time the rollout reaches the wider team, the elevation process is familiar and the helpdesk has data on the kinds of requests to expect.
The takeaway
For most firms, this is a low-cost, high-impact change. It reduces malware blast radius, eliminates a category of avoidable tickets, and aligns the endpoint estate with the principle of least privilege, which CISA names as one of its core cybersecurity practices.
