Hi :thumbsup:.

If your desktop is frozen...how can you check Winlogon usage of the CPU? If your desktop is not frozen, then you can easily check the status of any process, including Winlogon.

I don't know much...but it hardly seems likely that any user would ever be able to see Winlogon taking 99% of CPU cycles, unless something really atypical has occurred.

How long did this 99% for Winlogon last? What were you doing just before this occurred?

Are you using a firewall?

Do you have an AV program installed, updated, and running?

What programs do you use to scan your system for malware/spyware, etc.?

The problem could be that a program is starting up when you boot into your computer. Try clicking on start -> run -> and then type in "msconfig" and click on the startup tab. Afterwards, uncheck any program that you don't need running.

For example some of the programs that don't need to be in startup are: AOL, Quicktime, winamp, Itunes, etc.etc.
