I engaged "Dave's Computer" to build a new custom build Windows 11 computer as replacement for the Windows 10 machine. I presented my thoughts and needs to Dave about the new unit and he asked some basic questions as to my needs and want for the new unit. We touched on cost for the unit and I left...

Three Jobs, One Page: Repair, Reinstall, Upgrade
I pick the lightest path that will hold, and tell you which one before I start.
1
In-place repair install (Windows is damaged but still boots)
When the machine reaches the desktop but Windows Update fails, system files are corrupted or the Start menu is broken, a repair install rewrites the operating system underneath your files and programs. Microsoft's recovery documentation describes this route as one where "your personal files, apps, and settings are kept." I run it with current media, then confirm updates flow and your programs open.
2
Clean reinstall with your files preserved (Windows won't boot, or it's beyond repair)
When the machine loops on a repair screen, stops at Inaccessible Boot Device, or the install is too far gone to be worth patching, I clone the drive first. That clone is the safety net: documents, photos, bookmarks and mail data are copied off before anything is erased. Then a fresh Windows 11 goes on, drivers are brought current, updates are applied, activation is restored through the digital license tied to the board, and your files go back where they were. Programs are reinstalled from your list. It's the same process as my guide to a clean install of Windows 11, done by me.
If the drive is old or slow, this is the moment for an NVMe SSD. See my SSD upgrade service; the reinstall lands on the new drive and the old one stays as a backup.
3
Windows 10 to Windows 11 upgrade
Microsoft ended support for Windows 10 on October 14, 2025. The consumer Extended Security Updates program keeps security patches coming through October 12, 2027 for enrolled PCs, and after that the road ends. I check the desktop against Microsoft's Windows 11 requirements, fix the firmware settings that usually block the upgrade, then upgrade in place or do a clean install, whichever fits the machine.
What Each Path Keeps
The honest version of "will I lose anything," in one table.
| What's on the machine | Repair install | Clean reinstall (with clone) | Windows 10 to 11 in-place upgrade |
|---|---|---|---|
| Your files (documents, photos, desktop, downloads) | Kept in place | Copied off first, put back after | Kept in place |
| Installed programs | Kept | Reinstalled from your list | Kept, though a few very old programs may need a reinstall |
| Windows settings, Wi-Fi, printers | Kept | Set up fresh; I reconnect printer and network | Kept |
| Browser bookmarks and saved logins | Kept | Exported and restored | Kept |
| Outlook or other desktop email | Kept | Data files copied and reattached | Kept |
| Windows activation | Kept | Restored via the digital license on the board, or a retail key you supply | Carries over from Windows 10 |
| The corruption or malware that brought you in | Usually cleared; deep infections need a wipe | Gone | Carried along; upgrade a sick install and you get a sick Windows 11 |
Microsoft's "Reset this PC" option keeps files or removes everything, but either way "apps and settings are removed." That's why I clone before any reset or reinstall instead of trusting one option to keep what matters.
The Windows 10 to Windows 11 Upgrade, Step by Step
Most "can't run Windows 11" messages on a desktop are a settings problem.
Microsoft's published requirements for Windows 11 are a 1 GHz or faster 64-bit processor with two or more cores on its compatible list, 4 GB of RAM, a 64 GB drive, UEFI firmware that is Secure Boot capable, TPM 2.0, and DirectX 12 graphics. Nearly every desktop from the last several years clears the RAM, storage and graphics lines. Where towers fail is the firmware, the disk layout and the CPU list.
Firmware settings first. A desktop that shipped with Windows 10 often has the TPM (Intel PTT or AMD fTPM) switched off, Secure Boot disabled, and Windows installed in legacy BIOS mode on an MBR disk. None of those are hardware faults. I turn on the TPM, convert the disk to GPT without losing data, switch the board to UEFI boot and enable Secure Boot. The same machine then passes the check.
If the Windows 10 install is healthy, I upgrade in place and everything stays. If it's sluggish or half-broken, an in-place upgrade drags the problems forward, and I recommend the clean reinstall path instead, with a tune-up pass on the hardware side to finish the job.
When the CPU isn't on the list. Intel 7th generation and older, and AMD Ryzen 1000 series and older, aren't on Microsoft's supported processor list for Windows 11. Microsoft doesn't guarantee updates on unsupported hardware, so I don't quietly bypass the check. The real choices, from ESU enrollment to a board and CPU upgrade to replacement, are on my page about options when a desktop isn't compatible with Windows 11.
Want to try it yourself first? My guide to creating a bootable USB to install Windows covers the media; if you stall partway, bring the tower in. Staying on Windows 10 for now? See my Windows 10 repair and support page.
What It Costs
A flat number for the whole job, agreed before I touch the drive.
I quote the job at drop-off once I've seen the machine and what's on it, and nothing is charged until you approve the number. The three paths are different amounts of work, so they carry different quotes; the variables are how much data has to be cloned and restored, how many programs need reinstalling, and whether a new SSD makes sense at the same time.
✓ Flat rate, not hourly. The quote is the price; a reinstall that fights me for an extra hour doesn't cost you more. Most jobs are done in 24-48 hours, same-day rush is available, and most work carries a 30-90 day labor warranty.
Moving to a new desktop instead of fixing the old one? That's my old PC to new PC data transfer service, which uses the same cloning tools to move everything across.
Signs Your Desktop Needs This
Match the symptom to the path.
| What you're seeing | What it usually means | Likely path |
|---|---|---|
| Windows Update fails with the same error, or updates install and roll back | Damaged system files | Repair install |
| Blue screens with different codes, on a machine that passes hardware tests | Corrupted drivers or OS files | Repair install; clean reinstall if it recurs |
| Automatic Repair loop, Inaccessible Boot Device | Damaged boot files or registry; drive health checked first | Clean reinstall after a drive test |
| Slow from the first click after years of installs and uninstalls | A mess no cleaner will untangle | Clean reinstall, often with an SSD |
| "This PC doesn't currently meet Windows 11 system requirements" | Firmware settings, MBR disk, or an unsupported CPU | Windows 11 upgrade, or the options page if the CPU is out |
| Windows 10 nagging about end of support, no ESU enrollment | Unpatched OS on a machine that probably qualifies | Windows 11 upgrade |
| Pop-ups, hijacked browser, unknown programs appearing | Malware, not corruption | Virus removal first |
What I Need From You at Drop-Off
Five minutes at the counter saves a day of back-and-forth.
Bring the tower and the power cord; my page on bringing a desktop to the repair shop covers how to carry it safely. At the counter I'll ask for:
Your Windows sign-in password or PIN, and the Microsoft account email if the machine uses one. Without it I can't verify what's on the drive or confirm activation.
License keys or logins for programs you want back. Office is tied to your Microsoft account; Adobe, QuickBooks, tax software and antivirus each have their own login or key. Windows reactivates from the digital license on the motherboard, but the programs on top of it don't.
An idea of what matters on the drive. Family photos on a second drive, a QuickBooks company file, an old Outlook archive. The clone catches everything, but knowing what you care about tells me what to verify by hand, and a second drive is something I'd rather hear about before I start.
When a Reinstall Won't Fix It
There are three situations where I'll stop and call you before doing the work you asked for.
The drive is failing. A Windows install that keeps corrupting itself, boots that take longer every week, files that open as garbage: those are drive symptoms, and reinstalling onto a dying drive buys you a few weeks at most. Every reinstall at my bench starts with the health check I describe in how to check SSD health. If the drive is bad, the job becomes a new drive plus reinstall, and if the old one is already hard to read, it becomes data recovery first.
It's malware, not corruption. Redirecting browsers, fake antivirus warnings, programs that come back after you remove them: a repair install won't clear an infection, and a straight file restore can carry it back onto the fresh system. That's a virus removal job, $149 flat, and restored data gets scanned first.
The hardware is the problem. Random restarts, crashes under load, freezes with the fans screaming: Windows gets blamed for a failing power supply or a memory fault all the time. If the pattern points at hardware, a reinstall is the wrong purchase and the tower goes through the diagnostic side of the shop.
And if the desktop isn't worth the work at all, I'll say so; my page on whether a computer is worth repairing shows how I make that call.
What I See on the Bench in New Jersey
Composite examples, built from the kinds of jobs that come across my Somerville counter.
A Bridgewater customer's Dell office tower stuck on Windows 10. PC Health Check said it couldn't run Windows 11. The 8th generation Intel processor was well inside the supported list; the blockers were PTT turned off in the BIOS and an MBR disk from a Windows 7 era install. TPM on, disk converted to GPT, UEFI with Secure Boot, upgraded in place. Every program and file stayed put.
A Hillsborough family's home-built gaming desktop that wouldn't finish booting. Spinning dots, then Automatic Repair, every time. The NVMe drive tested healthy, so I cloned it, did a clean Windows 11 install, restored the user folders and reinstalled the game launchers. The second drive full of games was left untouched and relinked.
A Franklin Township customer's HP desktop that "needed Windows reinstalled" for slowness. The health check showed a hard drive with a growing reallocated sector count. I called before doing anything and quoted a new SSD plus the reinstall instead. Files came off fine, Windows 11 went on the SSD, and the old drive went home as a spare copy.
Bring the tower to Somerville and I'll tell you at the counter which path it needs. The job is quoted flat once I've seen the machine, and nothing is charged until you approve it.

I have been going to Dave's Computers for years because he always fixes my problems. I also use his anti-virus and it is as good as any, if not better, than others that I would have to pay much more for. If you're having problems, go to Dave's. He doesn't break the bank and he solves the problems.

Over the last decade or so, whenever I had a computer problem, I went to Dave. I recently had a very worrisome crash; the system failed to boot up. (I hadn't needed to use him for about 3 years.) I paid the "rush fee" on Saturday when dropping the machine off with the weekend agent. By Monday...

Windows Reinstall and Upgrade Questions From NJ Customers
What people ask at the counter before handing over the tower.
What does a Windows reinstall service include?
For a desktop tower: cloning the drive first so your files are safe, a fresh installation of Windows 11 (or Windows 10 where the hardware requires it), current drivers, all updates, activation restored, your files put back where they were, and the programs you asked for reinstalled. You pick it up signed in and ready to use.
How much does a Windows reinstall or Windows 11 upgrade cost in NJ?
I quote the job at drop-off once I've seen the machine and what's on it, and nothing is charged until you approve the number. It's a flat rate for the whole job, not hourly. Most jobs are done in 24-48 hours, and same-day rush is available.
Will I lose my files if you reinstall Windows?
No. Before a clean reinstall I clone the drive, so documents, photos, desktop, downloads, bookmarks and email data are copied off and put back afterward. A repair install keeps files and programs in place without a wipe. The only thing a clean reinstall doesn't bring back on its own is programs, which I reinstall from your list.
Do I need my Windows product key for a reinstall?
Usually not. Most desktops from the last several years carry a digital license tied to the motherboard, and Windows reactivates on its own once the fresh install connects to the internet. If your copy was activated with a retail key, bring the key or the Microsoft account it was linked to.
Can you upgrade my Windows 10 desktop to Windows 11?
If the processor is on Microsoft's supported list and the board has TPM 2.0 and UEFI with Secure Boot, yes. Often the hardware is fine and only the firmware settings or the disk partition style are blocking the upgrade, which I fix at the bench. If the CPU itself isn't supported, I'll lay out the options instead of forcing it.
Is Windows 10 still safe to use in 2026?
Microsoft ended Windows 10 support on October 14, 2025. A PC enrolled in Microsoft's consumer Extended Security Updates program keeps getting security updates through October 12, 2027. A Windows 10 machine that isn't enrolled is no longer being patched, and it needs a plan rather than being left alone.
