Installation help
Official Microsoft download links and step-by-step installation flows for every product we sell — Windows, Office, Server, SQL, Visual Studio, Project, Visio and Microsoft 365.
Before you start: a five-minute pre-flight
- Back up. Anything irreplaceable goes to OneDrive, an external drive or your cloud of choice. Windows reinstalls erase the system partition.
- Check hardware. Run Microsoft's PC Health Check for Windows 11. For Office, any PC made in the last decade qualifies.
- Confirm edition. The product page and your order email list the exact edition. Installing Home when you bought Pro causes 0xC004C003 at activation.
- Have the key ready. Copy it out of the order email; never re-type 25 characters by hand.
- Plug in. Laptops need to be on AC power during a Windows install — battery interruptions corrupt the system partition.
Windows 11 — clean install
- Go to microsoft.com/software-download/windows11 and download the Installation Assistant or the ISO.
- For a fresh install, write the ISO to USB with Rufus (8 GB+ stick). In Rufus, pick "Standard Windows installation" and tick "Remove requirement for 4 GB+ RAM, Secure Boot and TPM 2.0" if your machine fails the hardware check.
- Boot from USB (F12 / F10 / Esc varies by manufacturer). Choose "Custom: Install Windows only".
- Delete every partition on the target disk, then click Next — Windows creates the partitions it needs.
- Skip the product key prompt with "I don't have a product key".
- If asked about a Microsoft account on a Pro install, you can pick "Sign-in options → Domain join instead" for a local account.
- Once on the desktop, open Settings → System → Activation → Change product key, paste your key, click Activate.
Windows 11 — in-place upgrade from Windows 10
- Run the Installation Assistant inside Windows 10 — it keeps files, apps and settings.
- If the assistant blocks on TPM 2.0, enable PTT (Intel) or fTPM (AMD) in BIOS; both implement TPM 2.0 in firmware on most chipsets from 2017+.
- After upgrade, paste your Windows 11 key via Settings → Activation. Your Windows 10 digital licence is not consumed — it remains valid for a future re-downgrade.
Office 2024 / 2021 Pro Plus
- Uninstall any existing Office trial via Settings → Apps.
- Download the Office Deployment Tool from Microsoft Download Center.
- Use the configuration file we email with your order (it pins to the Perpetual channel).
- Run
setup.exe /configure config.xmlfrom an elevated CMD in the ODT folder. - Open Word → File → Account → Activate, paste your key.
Minimal ODT config — Word + Excel + Outlook only

</Configuration>Replace PIDKEY with your retail key (it's the 25-character string from the order email). Channel becomes PerpetualVL2021 for Office 2021.
Microsoft 365 (Family / Personal / Business)
- Sign in at account.microsoft.com (or admin.microsoft.com for Business).
- Open Services & subscriptions → Redeem a code → paste the key.
- Click "Install" on the dashboard; the Click-to-Run installer downloads the latest channel build.
- Share Family seats from family.microsoft.com → Add member.
Windows Server 2025 / 2022
- Download the evaluation ISO from Microsoft Evaluation Center.
- Install and choose your edition (Standard / Datacenter / Essentials).
- Open elevated PowerShell, run
dism /online /set-edition:<edition> /productkey:<your-key> /accepteulato convert from evaluation. - Reboot. Confirm activation via
slmgr /xpr.
SQL Server 2025 / 2022
Download from microsoft.com/sql-server, run setup, select the edition matching your key, paste the product key on the Product Key screen. For unattended deployments use setup.exe /Q /IACCEPTSQLSERVERLICENSETERMS /ACTION=Install /FEATURES=SQLEngine /PID=<key>.
Visual Studio 2025 / 2022
Download the bootstrapper from visualstudio.microsoft.com, install, then Help → Register Product → Unlock with a Product Key. Per-workload installs cut disk usage from ~50 GB (full) to ~12 GB (e.g. ASP.NET + Node.js).
Project & Visio (perpetual)
- Uninstall any C2R Microsoft 365 Project/Visio trials first — perpetual and C2R cannot coexist.
- Run ODT with the Project- or Visio-specific config from your order email.
- Activate from File → Account inside the app.

Common install errors
Pending Windows Update lock. Reboot and retry — or run sfc /scannow first.
Setup couldn't find a required file. Re-download the ISO; the previous copy is corrupted.
Driver incompatibility during Windows upgrade. Update GPU and storage drivers before retrying.
TLS / .NET update blocked. Confirm internet, disable VPN, disable third-party AV during install.
Office ODT couldn't download from the CDN. Allow officecdn.microsoft.com through your proxy/firewall.
Click-to-Run service stopped. Start the 'Microsoft Office Click-to-Run Service' from services.msc.

Frequently asked
- Where do I download Windows 11 or Office 2024?
- Always from Microsoft directly: Windows 11 from microsoft.com/software-download/windows11, Office 2024 from microsoft.com/microsoft-365/get-office. Never download installers from third parties — even from us.
- Do I need to uninstall the trial first?
- Yes — uninstall any pre-installed trial of Office before activating a perpetual Office 2021/2024 key, or activation will fail with error 0x80072F8F.
- Can I install on a new PC?
- Yes for retail keys (one transfer per replacement device). OEM keys are tied to the first motherboard. If unsure, the product page lists the license type.
- What are the Windows 11 hardware requirements?
- 1 GHz dual-core 64-bit CPU on Microsoft's CPU list, 4 GB RAM, 64 GB storage, TPM 2.0, Secure Boot capable UEFI firmware, DirectX 12 graphics. Run PC Health Check to confirm. Most PCs from 2018 onwards qualify.
- How do I avoid the Microsoft account prompt during Windows 11 setup?
- On the network screen press Shift+F10, run 'oobe\BypassNRO', the PC reboots and the next pass exposes a 'I don't have internet' option which unlocks the local-account path. (Removed in some 24H2 builds — install offline by unplugging the ethernet/disabling Wi-Fi.)
- Can I dual-boot Windows 11 with Linux?
- Yes. Install Windows first, shrink its partition from Disk Management, then install your Linux distro into the free space. Grub will pick up Windows automatically.
- How big is the Office 2024 installer?
- About 4 GB downloaded, ~7 GB on disk after install. ODT streams only the components in your config.xml — you can ship Word + Excel + Outlook only and save 2 GB.
- Does Microsoft 365 Family work outside the country of purchase?
- Yes. The 6 seats can be used worldwide; only the billing address must match the original storefront country. Travelling abroad does not interrupt the subscription.
