What Was Happening
A customer in Putney SW15 brought us a custom-built PC with an instruction we hear less often than you might expect: wipe the whole thing and install a fresh copy of Windows 10 Pro. Nothing on the drive needed keeping.
Most machines arrive with a symptom and a question. This one arrived with a decision already made. There was no fault to chase and no data to nurse — the customer knew exactly what they wanted the machine to become and simply wanted it done properly.
A brief like that is deceptively simple, and its two halves matter equally. “Wipe it” is the destructive half. “No data required” is the half that makes the destructive half safe. There was a third detail worth noticing too: the request was for Windows 10 Pro, by name, not just “Windows” — and people rarely name an edition unless the machine has a job that needs it.

Our Diagnosis
There was no fault-finding to do here, and we won’t dress the job up as if there were. But every wipe has to pass through a gate before any work starts, and we treat that gate seriously precisely because this kind of job is easy to do and impossible to undo.
A proper wipe is irreversible in a way very little else on our bench is. Replace a screen and the old panel still exists. Reinstall Windows over a damaged copy and the files can often be preserved. Wipe a drive and that’s the end of it — no undo, no realistic recovery afterwards. So before anything destructive happened, the question was put plainly: is there truly nothing on this drive you’ll want next month? Not “probably nothing” — nothing. The answer was recorded on the job when it was booked in — no data required — so the decision existed in writing before the wipe, rather than being remembered differently after it.
We labour the point out of experience. The photographs people forget about live in odd folders. Older email setups keep years of messages in local files that don’t follow a webmail login around. It is a far better conversation to have before the drive is blank.
With the gate passed, the rest was quick. Being custom-built counted in the machine’s favour: no manufacturer recovery partition to preserve, no preloaded extras to work around. A clean install on a custom build, from standard media onto an empty drive, is about as clean as clean gets.
How We Fixed It
The work was exactly what was asked for.
The hard drive was wiped back to blank — the old operating system, the old partitions and everything the customer had decided not to keep, all of it gone. That is the point of the job: nothing survives to travel forward with the machine.
Onto the empty drive went a clean installation of Windows 10 Pro. A fresh install with nothing carried over is the one state of Windows where you know precisely what is on the computer: the operating system, and nothing else. We made sure it started properly and settled reliably at the desktop before calling the job done.
It’s worth being equally clear about what this job was not. A wipe-and-reinstall renews the software side of a computer completely and the hardware side not at all. The same drive, memory and power supply stayed exactly as they were — reinstalling Windows services none of them, and says nothing about how much life an ageing drive has left. The machine left us with a genuine fresh start, not a new lease of mechanical life, and we’d rather say that plainly than let a clean desktop imply more than it should.
The Result
Everything done as briefed: drive wiped, Windows 10 Pro installed, the PC running cleanly. We phoned to say it was ready and — in the time-honoured way of these things — reached voicemail, so the message was left and the machine sat finished, waiting for collection.
The work carried our standard 90-day warranty. On a job like this that covers the installation itself: if the fresh copy of Windows misbehaved through some fault in our work, we’d put it right. What no warranty can cover is what gets installed on top of a clean system afterwards, or an unrelated hardware failure further down the line — a boundary we spell out at handover rather than leave to be discovered.
Why This Happens
Windows installations age in a way that has little to do with the hardware underneath them. Years of programs installed and half-uninstalled, trial software that outstayed its welcome, start-up entries nobody remembers approving — it all accumulates, and Windows faithfully carries the sediment forward through every update. Clean-up tools help at the margins. A wipe is the only version of “clean” that genuinely resets the story to zero, which is why, on an otherwise healthy machine, it remains one of the most transformative jobs we do for the least drama.
The Pro request deserves a word, because most home users never think about editions at all. Windows 10 shipped as Home and Pro: Pro adds full-drive encryption with BitLocker, proper inbound remote access, and the management features workplaces rely on. This job came through in the late summer of 2020, when a great deal of London was abruptly working from spare rooms and personal machines were being pressed into work service. Someone asking for Pro by name usually isn’t guessing — the edition is the point.
One more honest note for machines of this vintage. This PC’s storage was a mechanical hard drive, and a clean install makes a hard-drive machine feel better without making it fast: Windows sheds its sediment, but the drive still reads and writes at mechanical speeds. Had the brief been “make it quicker” rather than “make it clean”, the conversation would have been an SSD — for computers of that era, the single biggest improvement available. The brief here was a clean slate, so that is what was delivered.
Finally, honesty demands a time-stamp, because this page describes a 2020 job and operating systems don’t stand still. Windows 10 — current and correct then — reached the end of its support life in October 2025. The same fresh-start request today would be a Windows 11 conversation, and on an older custom build that’s a real conversation rather than a formality, because Windows 11’s hardware requirements exclude plenty of perfectly serviceable machines. If yours is one of them, we’d rather tell you so at the counter than install something unsupported and call it a fresh start.
What to sort out before you ask for a wipe
This customer had the easy version of the pre-wipe checklist: nothing to keep. If you’re less certain, the time to become certain is before the machine reaches the bench. The usual casualties, in rough order of heartbreak: photos and documents living outside the obvious folders, browser-saved passwords that were never synced to an account, local email archives, and licence keys for paid software — the installer can usually be downloaded again; the key often can’t. Anything that only syncs when told to should be told to, and given time to finish, before the drive is handed over.
And if the machine won’t start at all, that is not the moment to authorise a wipe out of frustration. Getting data off a drive first is routine work — and where a drive has genuinely failed, our data recovery is charged only if the recovery succeeds, so finding out what’s retrievable doesn’t cost you a gamble.
Local Help in Putney SW15
If a computer of yours has reached the point where a fresh start makes more sense than another round of clean-up — slowed to a crawl, cluttered beyond rescuing, or changing roles and you want nothing carried over — a wipe and clean install is quick, decisive and completely effective, provided the data question is answered first. That part we’ll always insist on getting in writing.
