Enable File & Folder Properties 'Security' Tab in Windows XP Home

Update: This trick enables the display of pro security options in XP Home, but I'm not sure the permissions are actually valid...

If Microsoft ever found out about this, I'm sure they would "have a cow," as we used to say. Here is a simple patch (brilliant, really) that is small, harmless, reversible, which immediately and effectively enables the 'Security' tab in Windows XP Home to make it like XP Pro.

Scroll to the bottom and download "Security for files and folders."

Windows 2000 Server Display Problems

When I uninstalled PCanywhere from our Windows 2000 Server (Dell Poweredge 2600 Tower) at work, my display adapter stopped working (i.e. I could only display in 16 colors and at limited resolution).

My first attempt at troubleshooting was to buy a PCI video, card and install it, but that still didn't work. Whether it was the onboard video, or the new video card, it kept giving me "Code 31" errors when I clicked the device properties in the device manager.

I kept hunting around on the web, and this is what finally led me to a solution:

Even though this link is about CD-ROM devices, the problem was the same for me and my display adapter trouble. In the registry key [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E968-E325-11CE-BFC1-08002BE10318}] there was an entry called "UpperFilters" that was set to "aw_host." It turns out this was left over from PCanywhere (found that out by Googling "aw_host.") I deleted that registry entry, and now my video works again! (high color, higher resolution display settings work now.)

I haven't tried the regular on-board video, but it probably still works too.
