Had 8GB of spare memory so popped it into an old Intel Core 2 Duo E4600 and installed Windows 7 x64 bit as the processor was x64 compatible.
Checked windows system and noticed it had 8GB (3.25GB usable). Strange, so I upgraded the bios to the latest version and checked that it was seeing 8GB, which it was.
I noticed under msconfig.exe (just type it into search and you will find it, or usually under C:\Windows\System32)
Click "Boot" Tab
Click "Advanced options"
"Maximum Memory" was ticked - so I un-ticked it and rebooted
And now I have the full 8GB of ram available.
If you want to be able to search Active
Directory in Windows 7 this is quite easy.
First install the Remote Server Administration Tools for Windows 7 (currently with
Service Pace 1 (SP1)) at:-
The install will looks something like this:-
Once Installed you now need to add this feature.
Go to Control Panel - Programs
Under "Programs and Features" select "Turn Windows Features on or Off"
Scroll down and expand "Remote Server Administration Tools"
Expand "Role Administration Tools" and select all under "AD DS and AD LDS Tools"
Click OK and these will install.
Now under Start Button - All Programs - Administrative Tools you will have some new programs. The main one to use is "Active Directory Users and Computers".
