(*): ISC rating
  • We use 4 levels:
    • PATCH NOW: Typically used where we see immediate danger of exploitation. Typical environments will want to deploy these patches ASAP. Workarounds are typically not accepted by users or are not possible. This rating is often used when typical deployments make it vulnerable and exploits are being used or easy to obtain or make.
    • Critical: Anything that needs little to become "interesting" for the dark side. Best approach is to test and deploy ASAP. Workarounds can give more time to test.
    • Important: Things where more testing and other measures can help.
    • Less Urt practices for servers such as not using outlook, MSIE, word etc. to do traditional office or leisure work.
    • The rating is not a risk analysis as such. It is a rating of importance of the vulnerability and the perceived or even predicted threatatches.

Win7/64bit computer stuck at Stage 1 of 3 - 23% complete. (after being told to reboot after patching)

I seem to remember this happening 2-3 months ago.

Looks like KB3061518 is breaking client communications with Catia (DSLS) license servers. Removing the update fixes the problem.

Systems stuck on configuring updates stage 3 of 3. [can also be 1 of 3 or 2 of 3 as noted above]

Solution: hit control alt delete.

No root cause, no one particular update has been identified.

Had one of those happen today, where CTRL-ALT-DEL worked. My system from yesterday tho was completely locked up and its problem happened BEFORE the reboot. The little circle was not spinning and there was no hard drive activity. Did a hard reset on that one and everything came up fine.... and all patches showed as installed.
