Hi there, I have a dell slic 2.1 tabel, with a DELL.XRM-MS digital license installed and a dell ultimate oem slp key. I activated a long time ago, can't remember when actually... Well anyways, a few days ago Windows was suddenly deactivated. My question is why and how do I solve it? I guess this happend after I updated my windows last time. Is there a new update that microsoft released that made this happen? I've tried several new slp keys but without success. Thanks for any answer.
