A Good Time to Give Your Computer Some Attention
Computers accumulate clutter just like desks, filing cabinets, and storage rooms.
Old downloads pile up. Applications get installed and forgotten. Files are saved in multiple locations. Browser extensions accumulate. Updates get postponed. Storage slowly fills. Employees learn to live with computers that take longer to start or regularly interrupt their work.
National Clean Out Your Computer Day is a useful reminder to address some of that digital clutter.
But cleaning up a business computer is about more than freeing disk space.
Done properly, computer maintenance can help improve:
- performance,
- productivity,
- organization,
- security,
- reliability,
- and the useful life of your equipment.
You do not need to wait for one particular day each year, either. These are good habits to incorporate into regular computer maintenance throughout the year.
Here are 10 practical places to start.
1. Delete Files You No Longer Need
The Downloads folder is often a good first stop.
It may contain:
- old installers,
- duplicate documents,
- exported reports,
- temporary PDFs,
- images,
- ZIP files,
- outdated project files,
- and documents that were only needed once.
Desktop folders can become cluttered in the same way.
Deleting files you genuinely no longer need makes important information easier to find and can free storage space.
But in a business environment, do not simply delete everything that looks old.
Some files may be subject to:
- company retention policies,
- customer requirements,
- legal requirements,
- accounting requirements,
- or compliance obligations.
If you are unsure whether a business record should be retained, check before deleting it.
Once unnecessary files have been removed, empty the Recycle Bin or Trash if you are certain you no longer need them.
2. Organize the Files You Need to Keep
Cleaning out a computer is also an opportunity to improve organization.
If employees routinely save files to:
- the desktop,
- Downloads,
- random local folders,
- email attachments,
- USB drives,
- or multiple different cloud locations,
finding the correct version of a document can become unnecessarily difficult.
Create a logical filing structure based on how your organization actually works.
That might involve folders organized by:
- customer,
- department,
- project,
- year,
- job number,
- document type,
- or another business-specific structure.
Use descriptive file names instead of names such as:
document1.docx
newversion.xlsx
final-final2.pdf
A clear naming convention makes information much easier to locate months or years later.
The goal is not to create dozens of complicated folders.
It is to create enough structure that employees know where information belongs and where to look for it later.
3. Remove Applications You No Longer Use
Over time, computers often accumulate software that nobody needs anymore.
That might include:
- trial software,
- old utilities,
- applications related to former vendors,
- software installed for a one-time project,
- outdated versions of applications,
- and programs employees no longer recognize.
Unused software can consume storage and sometimes continue running services in the background.
More importantly, unnecessary applications represent additional software that may need to be patched and maintained.
Before uninstalling business software, make sure you understand what it does.
Employees should not randomly remove applications from company-managed computers simply because they do not recognize them.
When in doubt, ask IT.
A good cleanup should eliminate software that is genuinely unnecessary without accidentally removing something another system depends on.
4. Review Programs That Start Automatically
Some applications configure themselves to launch every time Windows or macOS starts.
One or two may not matter.
Over time, however, numerous startup applications can:
- increase login time,
- consume memory,
- run unnecessary background processes,
- and contribute to a computer feeling slower than it should.
Review the programs configured to start automatically.
Applications that employees use constantly may belong there.
Applications that are rarely used may not need to start every time the computer does.
Again, company-managed security, backup, monitoring, or IT-management software should not be disabled just because it appears to be running in the background.
If you are unsure what a startup program does, leave it alone and ask IT.
5. Install Operating System and Application Updates
Computer cleanup should include checking whether important software is current.
Updates frequently contain:
- security patches,
- reliability improvements,
- compatibility updates,
- bug fixes,
- and performance improvements.
That includes more than Windows or macOS.
Applications such as browsers, PDF software, productivity software, accounting applications, remote-access tools, and other business programs also require maintenance.
For business environments, patching is better handled as an ongoing managed process rather than relying on individual employees to remember to check for updates.
If a computer repeatedly cannot install current updates, that may also indicate that the hardware or operating system is reaching the end of its useful life.
6. Check Your Browser Extensions
Browser extensions are easy to install and easy to forget.
Employees may have added extensions for:
- screenshots,
- PDF conversion,
- shopping,
- search tools,
- password management,
- productivity,
- video,
- AI tools,
- or other purposes.
Periodically review what is installed.
Remove extensions that are:
- no longer needed,
- unfamiliar,
- unsupported,
- or not appropriate for business use.
Browser extensions can potentially access significant amounts of browser activity depending on the permissions they have been granted.
Businesses should consider having guidelines around which extensions are appropriate for company computers.
A browser with fewer unnecessary extensions is also easier to troubleshoot.
7. Review Browser Data—But Don’t Clear Everything Automatically
You will often see advice telling users to clear all cookies and browser cache as part of routine computer cleanup.
That is not always necessary.
Browser cache can help websites load efficiently, and deleting all cookies may sign you out of websites and remove useful preferences.
Instead, clear browser data when there is a reason to do so, such as:
- troubleshooting a website,
- resolving corrupted cached content,
- removing unwanted site permissions,
- or addressing a specific privacy or security concern.
A more useful routine task is reviewing browser settings and removing unnecessary:
- extensions,
- saved site permissions,
- notification permissions,
- and unwanted downloads.
This is especially important if a website has been allowed to display suspicious browser notifications or fake security warnings.
8. Check Endpoint Security and Security Alerts
Computer cleanup should include a basic security check.
For a business computer, that means more than simply running an antivirus scan once per year.
Verify that the organization's endpoint-security tools are:
- installed,
- active,
- current,
- communicating properly,
- and not reporting unresolved alerts.
Depending on the environment, that may include antivirus, endpoint protection, EDR, DNS filtering, or other security software.
Employees should not disable security software because it appears to slow down the computer or generates a warning they do not understand.
If security software repeatedly reports a problem, IT should investigate the underlying cause.
Cleaning up the machine is useful.
Making sure the machine is properly protected is more important.
9. Verify Your Backups Before Deleting Important Data
Before making major changes, make sure important business information is protected.
That does not simply mean asking:
“Do we have backups?”
A better question is:
“Do we have backups that we know we can restore?”
Important files may exist in:
- cloud storage,
- Microsoft 365,
- local computers,
- file servers,
- line-of-business applications,
- databases,
- and other systems.
Do not assume that every cloud application automatically provides the type of backup and recovery your business requires.
Backups should be:
- monitored,
- tested,
- retained appropriately,
- and protected against the same threats that could damage production data.
If the only copy of an important file exists on one employee's computer, that is a business risk worth correcting.
10. Look for Signs the Computer Needs More Than a Cleanup
Sometimes a computer is slow because it is cluttered.
Sometimes it is slow because something else is wrong.
Pay attention to recurring problems such as:
- unusually long startup times,
- frequent freezing,
- application crashes,
- recurring disk-space problems,
- excessive fan activity,
- unreliable Wi-Fi,
- repeated update failures,
- hardware warnings,
- or applications that no longer perform well.
If cleanup does not resolve the problem, the computer may need additional troubleshooting, more memory or storage, an operating-system repair, or replacement.
Employees should not have to spend months working around a machine that consistently interrupts their work.
This is one of the technology issues we discuss in Factors That Hinder Business Productivity — It’s Not Your Employees.
Sometimes the most productive solution is not another cleanup.
It is replacing technology that has reached the end of its useful business life.
Don’t Forget the Physical Computer
A computer cleanup can include the physical workstation too.
Dust can accumulate around:
- air vents,
- cooling fans,
- docking stations,
- monitors,
- keyboards,
- and other equipment.
Blocked airflow can contribute to excess heat and poor reliability.
Use appropriate cleaning methods and follow the equipment manufacturer's recommendations.
Avoid spraying cleaning products directly into electronics.
For laptops in particular, keeping ventilation areas clear is important.
Also take the opportunity to inspect:
- damaged power adapters,
- frayed cables,
- loose connections,
- unreliable docking stations,
- and other physical issues employees may have learned to tolerate.
Should Employees Clean Up Their Own Business Computers?
There are some cleanup tasks employees can safely perform themselves.
Organizing documents or cleaning out a Downloads folder usually does not require IT expertise.
Other changes should be managed centrally.
Employees should generally avoid independently:
- uninstalling unfamiliar business software,
- disabling startup services,
- removing security software,
- changing system policies,
- modifying network configurations,
- deleting business records without authorization,
- or installing unapproved cleanup utilities.
Be particularly cautious with programs advertised as:
“PC cleaners,” “registry cleaners,” “driver updaters,” “speed boosters,” or “system optimizers.”
A business computer should not require a collection of third-party utilities to remain functional.
If a system is performing poorly, identify the cause rather than installing another program that promises to make the computer faster.
Make Computer Maintenance an Ongoing Process
National Clean Out Your Computer Day can be a useful reminder, but business technology should not be maintained only once a year.
Some activities should happen continuously.
Updates should be managed.
Security tools should be monitored.
Backups should be checked.
Storage should be watched.
Aging hardware should be planned for before it fails.
Recurring problems should be investigated rather than accepted as normal.
That is one of the differences between reactive IT support and proactive technology management.
A well-managed computer should not require employees to become their own IT department.
Businesses that want ongoing management of workstations, users, updates, security, infrastructure, and technology planning can learn more about our Managed IT Services.
A Cleaner Computer Is Only Part of a Healthy IT Environment
Cleaning unnecessary files and applications is worthwhile.
But the larger goal is not simply to make a desktop look tidy.
It is to maintain computers that are:
- secure,
- supported,
- reliable,
- organized,
- backed up,
- appropriately configured,
- and capable of supporting employees without unnecessary interruptions.
Use National Clean Out Your Computer Day as a reminder to clean things up.
Then build processes that keep your computers healthy the rest of the year.
