You have setup a new server, created users, deployed the application on the users desktop but the users complain they cannot see the clock in the task bar. You can log on every user’s desktop and enable the clock by yourself. You can write HOWTO and leave it on the user desktops so users can by themselves enable the clock or you can make a little registry change that will enable the clock. I would choose the last solution.
Go to the HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\StuckRects2 and note key Settings
When the clock is disabled, the Settings value looks like this:
28 00 00 00 FF FF FF FF 0A 00 00 00 03 00 00 00 3F 00 00 00 1E 00 00 00 FE FF Ff FF E4 03 00 00 02 05 00 00 02 04 00 00
When the clock is enabled, the Settings value looks like this:
28 00 00 00 FF FF FF FF 02 00 00 00 03 00 00 00 3F 00 00 00 1E 00 00 00 FE FF FF FF E4 03 00 00 02 05 00 00 02 04 00 00
The ninth pair of hexadecimal values is what we need to edit. The 0A turns into a 02.
Restart server or kill explorer exe.
For multiple users export new reg key, and apply this to logon script for all your users. Use regedit.exe /q to quietly import new reg data.
