Multiple RDP Session in Windows 7 Professional

I’ve been searching for something like this for a loooooong time, and I was hoping way back before that it could be also done in Windows XP. So I was happy to I found a super simple one-work-done tutorial for Windows 7.

There’s a different version of tutorial actually base on what build you are using, and I took the chance of trying it for the Build 7100.

Anyway, just to proof that it is working. Am going to use my Sony Ericsson Xperia X1 with Windows Mobile 6.5 Remote Desktop Mobile installed. Below are the screen shots for proof that it is working.

I have 2 user accounts in my Windows 7, one is the default Administrator account, and one was the User account created while installing Windows 7 named “Chevi” (my son’s name).

To All Computer Cafe's providing games

While searching a way to Hide/UnHide my desktop icons in Group Policies. I noticed the Windows Components and tried to explore until I saw this functionality sitting there, waiting to be discovered ... and It's a way to disable/enable Windows+X key!!

Microsoft Windows Explained: Turn off Windows+X hotkeys.

Keyboards with a Windows key provide users with shortcuts to common shell features. For example, pressing the keyboard sequence Windows+R opens the Run dialog box; pressing Windows+E starts Windows Explorer. By using this setting, you can disable these Windows+X shortcut keys.

If you enable this setting, the Windows+X shortcut keys are unavailable.

If you disable or do not configure this setting, the Windows+X shortcut keys are available.

I know its so frustrating for gamers when they accidentally pressed the Window Key 20070529-windowskey-f1specially when they're playing on full screen mode. And some Computer Cafe's last resort is to pop out that key on the keyboard. But hey, there's a solution for this, Windows (at least 2000) provides a way to disable the Window Key.

Here's how to do it:

1. Open Group Policy: C:\WINDOWS\system32\gpedit.msc
(here's a screen shot)
run window 
2. Expand Adminstrative Templates Folder
3. Expand Windows Components Folder
4. Click Windows Explorer Folder
5. On the right panel, search for Turn off Windows+X hotkeys and double click on it
(here's a screen shot)
Group Policy
(after you doubled click on it)
turn off windows-x
6. Click Enabled and click OK Button
7. Log Off your computer session or Restart if needed.

and that's pretty much it.

whew! another trojan attack.. lucky i survived!

Thanks to Autoruns from SysInternals



Just downloaded a screensaver recently and enjoying the great 3d solar system view but after a couple of second a balloon pop-up notifying me that my Windows Firewall and Windows Update was disabled! So it got me thinking that the screensaver I've just downloaded was a trojan!! (stupid-stupid-stupid!)

A bit lucky i got my Windows Firewall back but ... I couldn't turn Windows Update on! its like something's monitoring it and keeping it disabled! hmmm.... tricky situation...

After a half hour of hunting ... I thought of using Autoruns to look more deeply in Windows autoruns and saw some weird dll filenames in:
  • Logon
  • Explorer - HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\ShellExecuteHooks
  • Internet Explorer - HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects
  • LSA Providers - HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SecurityProviders
I listed them and made a batch file so i don't have to type and delete them manually

----- deltroj.bat -----
@echo off
cls
echo deleting stupid trojans
echo deleting
echo d:\windows\system32\tptdclih.dll
del d:\windows\system32\tptdclih.dll

echo deleting
echo d:\windows\system32\pmnkkcsl.dll
del d:\windows\system32\pmnkkcsl.dll

echo deleting
echo d:\windows\system32\pmnmklbb.dll
del d:\windows\system32\pmnmklbb.dll

echo deleting
echo d:\windows\system32\jmvqbh.dll
del d:\windows\system32\jmvqbh.dll

echo done

pause
---- end ----

oh and btw, those are locked! means you can't delete them while WindowsXP is running or download Unlocker - that should help you delete those files ... or you can boot up in DOS mode ... errrrr .... how? I used BootCD from Hiren

hmmm... so after those stuff, I rebooted and bootup in normal WindowsXP, got some notifications about missing files... that means my OS is clean but I should do some manual clean up ... run Autoruns again and look on the tabs where I found the trojan files and deleted the entry!

and that's it!! :P stupid-me .... and dump-ass-a-hole trojan creator *wink*

Netlog and Fiendster SPAMMERS!

Have you been spammed lately?? I mean, someone's sent you a personal message or comment asking you to go to their site by clicking the link included in their message. Who want's to click that link?? I mean, yeah, might be someone out there who jut love porn sites. I mean, they just click it, wait for the p age, and after that, you computer go, BOOM!! not really BOOM like exploded, i mean SPYWARES!. Heh! too bad.

Anyway, did i say someone to the spammer? i mean something. That means, the profiles owner is not a Human! This is not a joke, and i'm talking technical. Ok, long story, short. They are called BOTS. NetlogBOT, FriendsterBOT, MySpaceBOT, BOT! BOT! BOT! an ugly, irritating BOT!

How are they created?
Of course, creating or registering a new profile is done with a human interaction. :p

THEN!
The BOT is released, sending cookies to the server acting they are logged in.
The BOT goes to some page where it can look for online members or new members.

The BOT is not choosy!
So, it goes through all those members, open their profile, and the BOT starts dumping crap!
And the bot will do the same thing to the others, and others, and others. And make the master satisfied and happy. :p

Ok. End of story, hope you guys learned something with this bit of information. I don't want to go deep, creating video or a flow, other might get confused, just want to give you a basic idea on how's and why's.
