Sometimes you just need to wipe the slate clean, especially if your system is corrupt or just clogged up. We can do a totally clean install of Windows or macOS for you. We'll save all your personal files first, then put them back afterwards. We'll hunt down all the correct drivers for your specific model and get all the updates done. The best bit? It comes back with none of that useless bloatware that manufacturers install. It will probably run faster than it did when you first bought it.

Popular os installation jobs by brand
Clean installs are the fastest way to fix a laptop that just feels broken. We do fresh Windows 11 setups on Dell Latitude business fleets, HP EliteBook rebuilds with driver stacks reinstalled, and ThinkPad clean installs after a swap to SSD. Add macOS reinstalls on MacBook Air and the odd ASUS ZenBook Windows reset, and that's a normal week. Every laptop brand we support is listed here.
