Hi, while installing Windows-updates, the activation was gone (popup window and notice in the right corner of desktop). After restarting, it was still deactivated and the desktop was black. Strange: SLIC Toolkit V3.2 shows all green, SLIC found, Key found and cert found. I removed the key and installed cert and the same key as before, Windows is activated again. But this is weird. I'm sure that no virus or malware is on this computer. -Foxconn-Mainboard with Dell-SLIC 2.1 -Windows 7 Pro 64bit -SLIC Toolkit V3.2 shows "no SLP1.0" and vendor is "Foxconn" instead aof Dell (doesn't matter, right?) So, is it known, that some Windows-updates remove activation of SLP-computers? My laptop got the same updates (same OS) and was never deactivated.
