Help! Lost WM5 Info Bar

[The Stranger]

My PPC has been acting up lately. While trying to fix some of its problems (fiddling with the registry, deleting some apps that I thought might be responsible, and cleaning up using MemMaid), I lost the top bar (whatever it is calld) that has the Windows logo, the drop down menu, the time and the OK/X-button. I think I can still access my file managers, including registry, and tools (if I am lucky, since the device's response time has deterioratd with everything that is happening). Any idea how to fix this problem short of a hard reset?

Regards
