Windows never logs off

[Zenun]

For the past week or so, every time I try to turn off my PC it just hangs on the logging off screen, even if I leave it on over night i'll come back in the morning to see it in the same state. This is especially annoying when I have a windows update and it tells me "Updating windows, do not turn off" Well, over 12 hours later it's still updating it... Any solutions?

Many thanks in advance

Have you installed anything that would have services/software running in the background, because I have seen this when Windows fails to unload a service.

Try uninstalling any new software you have installed recently, and see if it fixes it.

 

[anything I don't mind]

have you disabled prefetch?

you should not disable prefetch completely as it can cause problems with shutdown, if you have an ssd change the prefetch level in the registry.

1. Click Start – RUN, type “regedit”

2. Navigate to the following Regsitry key

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters]

HKEY_LOCAL_MACHINE
\SYSTEM
\CurrentControlSet
\Control
\Session Manager
\Memory Management
\PrefetchParameters

3. In the right-pane, look for the key “EnablePrefetcher” edit and set one of the following values as you require:

0 – Disable Prefetch in Windows

1 – Prefetch only Application Lauunch files

2 – Prefetch only Boot files

3 – Prefetch all

Say, you don’t need Application caching then simply set the value to “2″ which will prefetch only Boot files.

4. Reboot the system for the changes to take effect.
