A slow, cluttered, or corrupted operating system is one of the most common reasons office computers underperform, and in many cases a clean operating system installation resolves issues that no amount of software tweaking or antivirus scanning ever quite fixes. Bestcare Facilities Management provides this service across Nairobi offices running Windows, and where applicable, Linux-based systems for specialized workstations.
Why Businesses Need This Service
Operating systems accumulate clutter over time — leftover files from uninstalled programs, fragmented registry entries, and background processes that were never properly closed out. Eventually this buildup slows a machine down to the point where a fresh install genuinely outperforms weeks of troubleshooting. New computers also arrive needing proper configuration beyond the factory default, particularly for businesses with specific software, security, and network requirements that a generic setup doesn't account for.
An operating system installation is also the standard response to persistent malware infections that survive repeated cleaning attempts, since some infections embed themselves deeply enough that a full reinstall is the only reliable way to guarantee a clean system.
What the Service Includes
A proper installation goes well beyond just loading the OS. Bestcare technicians back up existing files before any wipe occurs, install and activate the correct license, configure user accounts and permissions appropriate to the office environment, and install essential drivers so hardware — printers, network adapters, peripherals — functions correctly from the first login. Business-critical software is reinstalled and configured as part of the same visit, minimizing the gap between wipe and full productivity.
For offices running multiple machines needing the same setup, a standardized image can be created and deployed across several units, saving considerable time compared to configuring each computer individually from scratch.
"A clean install done properly, with everything backed up and reconfigured correctly, solves more problems in one visit than months of patchwork fixes." — IT Support Technician, Bestcare
Estimated Cost of Service
| Service | Approximate Cost (KES) |
| Standard OS installation (single machine) | 2,500 – 5,000 |
| OS installation with data backup and restore | 3,500 – 7,000 |
| Business software reinstallation and configuration | 2,000 – 5,000 |
| Standardized multi-machine deployment (per unit) | 1,800 – 4,000 |
| Driver installation and hardware configuration | 1,000 – 2,500 |
Costs vary depending on the number of machines involved, whether data backup is required, and how much business-specific software needs reconfiguring afterward.
What to Expect During the Process
The process typically begins with a backup of all existing user files and settings, followed by the wipe and fresh installation itself. Once the base system is running, drivers and updates are applied, business software is reinstalled, and a final check confirms everything — network access, printer connectivity, and saved files — is back in working order before the visit is considered complete.
Frequently Asked Questions
Will I lose my files during an operating system installation? Not if backup is handled correctly beforehand — this is a standard part of our process, and files are restored once the new system is set up.
How long does a typical installation take? Most single-machine installations are completed within a few hours, though this can extend depending on how much software needs reinstalling afterward.
Do I need a valid license for my operating system? Yes, a genuine license is required for activation, and our technicians can advise on this if you're unsure of your current licensing status.
Can this fix a computer that's been running very slowly? In many cases yes, particularly when the slowdown is caused by accumulated software clutter rather than failing hardware.
