I have been receiving a message recently saying my copy of windows is not genuine.  I bought it directly from Dell a few years ago and this problem just recently stated happening.


The associated code is 0x8004fe21.  Dell has been less than helpful, despite me having purchased the full warranty and them saying that I would be covered if I have any problems with the PC.  Other issues I've been having are my laptop randomly shutting off, but this is probably do to the huge motherboard flexing a little...another thing I've been trying to get Dell to fix properly for over 6 months.


Anyways...the issue is the 0x8004fe21 windows not genuine...any help would be appreciated!  Let me know what info you need and how to get it.

Check the report for the 0x8004FE21 validation code error. If, under the "file scan data" header, there is a "file mismatch" error, try running sfc /scannow from the command line.


If it's not a corrupt system file, try calling Microsoft and re-activing over the phone. At the Start menu, type slui.exe 4 and press enter. Enter the country you live in, and select the Phone Activation option. Call the number listed.


If that doesn't resolve it, it may be malware. Run a full scan and make sure your system isn't infected.

I ran in to that problem once and it turned out to be because I had replaced my HDD and when Windows tried to validate it thought it was on a different computer. A call to microsoft took care of the issue.

A change of hard drive should not impact PA...unless the replacement drive reflects a Windows install from another system/motherboard.
