What this is

When do you need a Confirmation ID?

Microsoft sometimes refuses online activation and pushes you to activate by phone. That is normal, and it does not mean anything is wrong with your key.

Telephone activation

Windows or Office shows an activation wizard asking you to call Microsoft and read out a long Installation ID. This tool replaces that call.

After a hardware change

Replacing a motherboard, hard drive or a large amount of hardware can make Windows ask to be reactivated. Phone activation is the usual route.

Error 0xC004C003 and similar

Some activation errors send you to the telephone path. If you have been given an Installation ID, this is the right page.

Step by step

How to find your Installation ID

The Installation ID is a long number, usually nine groups of seven digits, that Microsoft shows you during telephone activation.

Windows 11, 10, 8 and 7

1

Open the activation wizard

Press the Windows key and R together, type slui 4 and press Enter.
2

Choose your country

Pick your country or region from the list, then click Next.
3

Copy the Installation ID

Windows displays it as nine blocks of seven digits. Type or paste it into the form above.
4

Enter your Confirmation ID

Back in the wizard, click Enter confirmation ID and paste the code this page gave you. Activation completes immediately.

Microsoft Office

1

Open any Office application

Word, Excel or any other app in the suite. Go to File, then Account.
2

Start activation

Choose Activate Product or Change Product Key, then pick the telephone option when it is offered.
3

Copy the Installation ID

Office shows the same style of long number. Paste it into the form above.
4

Enter your Confirmation ID

Type the code back into the wizard and confirm. Office activates without a call.
Tip: the form above also accepts a screenshot. If typing forty-odd digits is painful, use the Select image button or simply paste a screenshot of the wizard with Ctrl and V, and the Installation ID will be read from it.

Common questions

Still stuck? Email Support@kymakers.com and you will normally have a reply within the hour.

Yes, for Kymakers customers. Every order comes with a Tempcode that unlocks this tool, so there is nothing extra to pay. It is part of what you get when you buy your key here rather than somewhere that disappears after checkout.

In the email we sent when your key was delivered. If you cannot find that email, check your spam folder first, then write to Support@kymakers.com with your order number and we will resend it.

It is a long number that Microsoft generates on your computer during telephone activation, normally shown as nine groups of seven digits. It is unique to your machine and your product key, and it is what the Confirmation ID is calculated from.

No. Telephone activation is a normal Microsoft process and it is triggered by all sorts of ordinary things, including hardware changes, reinstalling Windows, or activating on a machine with no internet connection. Every key we sell is genuine and covered by our warranty.

Double-check that you copied the Installation ID exactly, with no missing digits, and that you did not close and reopen the wizard between generating the code and entering it. Reopening the wizard produces a new Installation ID, which makes the old Confirmation ID invalid. If it still fails, email us and we will sort it out.

This tool is for keys purchased from Kymakers, because the Tempcode comes with your order. If you bought elsewhere, your seller should be providing the same support.
