Windows 8 "license is invalid" after Windows updates (help please!)

Hello

I have a C540 all in one (no load) running Windows 8 and noticed yesterday that Windows updates have been failure for months then tried to run all the updates so that I can update to 8.1 (and, possibly, 10). At that time (and since purchase - I'm the original purchaser) Windows 8 has been activated very well.

There were various failures and reversions of updates and now Windows does not recognize the Activation Code. The key is material, it shows that I have a key in the registry, but when I entered in the service of Activation of Windows I get the error:

The following error occurred while trying to use the product key:

Code:
0xC004F01F

Description:
The Software Licensing Service determined that the license is not valid.

Microsoft helpfully told me this isn't their problem because it is an OEM license (even if the only thing I've done is apply the updates of Windows) and I need to buy a key to sales at retail. Lenovo speaks for me because I'm out of warranty.

Someone at - it ideas or experience or I'll just have to hit this PC with a massive hammer and not buy Lenovo or authorized OEM PCs again?

Thanks in advance!

I think I have a half today to answer my own question.

Today (without any changes made to anything) the key to Activation of Windows 8 was suddenly recognized and valid again. Now install each windows update individually also works.

I think that it is possible, but there is an intermittent hardware fault kind on the C540 causing quite different material for the MS license not to recognize the configuration (and think that the license is not valid for the PC), whatever it is not permanent.

Then - in terms of correction... Well I don't have - he went just by itself and I guess he'll be back one day...
