Fast User Switching Slow

[Jamie]

Within the last week or so, fast user switching has gone from fast to very
slow. It takes 45-60 seconds, once a switch command is issued, until I see
the screen to pick the user. In the meantime, Vista displays a Please Wait
screen.

I believe this began after applying several Windows Updates. I've installed
no other software recently. I manually applied KB938194 and KB938979 on
8/19. Automatic updates applied KB935652 on 8/20 and a Windows Update
software update (no KB mentioned in update history) on 8/22.

Anyone experienced this problem? Anyone applied the four updates above and
see any problems?

Running Vista Ultimate 32-bit. 2 GB RAM. P4 2.53 GHz. Raptor 150 GB SATA
with ~75 GB free.

Wanted to add that I'm using a ATI Radeon X1300 AGP graphics card with 256
MB RAM.

I'm seeing the same thing on both Vista 64 and Vista 32. Saw a
reference that it may be related to anti-virus. Are you running AVG?

Further information: I uninstalled AVG, restarted, and user switching
became normal again. However, after re-installing AVG, the problem has
not recurred.

During the reboot, Windows said it was installing and configuring
updates, so it may have been a Windows update (probably from 8/20)
that didn't force a reboot, but needed one.

Issue seems to be related to a pending restart due to update. Not sure why
Vista doesn't just reboot automatically after installs as it is configured
to do. Something hardware or software related is likely preventing the
automatic restart.

Manual restart clears up the slow switching. It's occured again since my
original problem. Manual restart cleared it up again.
