To support 64-bit platforms such as Intel Xeon, Intel Core 2, AMD Opteron and AMD Athlon 64, Microsoft released 64-bit versions of every edition of Windows Vista except for the Starter edition. These editions can run 32-bit programs by running them within the WOW64 subsystem. Most 32-bit programs can run natively, though applications that rely on device drivers will not run unless those device drivers have been written for 64-bit Windows. Older hardware doesn't have the necessary support to get the drivers written.
Other applications may have difficulty as well. For example, the Visual Basic 6 IDE will run natively on 32-bit editions, but will not run at all on 64-bit editions. Some application vendors will only provide full / premium product versions for 64-bit Vista and cut down versions for 32-bit Vista (e.g. Adobe Premier Elements is 32-bit and the full Adobe Premier is available for 64-bit Vista - with more capability but at a much higher price).
Various reviewers have reported that the 64-bit editions of Windows Vista outperform their 32-bit counterparts in synthetic benchmarks such as Pass Mark. For example, in early testing of 64-bit support in Photoshop for Windows, overall performance gains ranged from 8% to 12%. Those who work with extremely large files may realize noticeably greater gains in performance, in some cases as dramatic as ten times the previous speed. This is because 64-bit applications can address larger amounts of memory and thus result in less file swapping - one of the biggest factors that can affect data processing speed.
All 64-bit versions of Microsoft operating systems currently impose a 16 TB limit on address space. Processes created on the 64-bit editions of Windows Vista can have 8 TB in virtual memory for user processes and 8 TB for kernel processes to create a virtual memory of 16 TB. In terms of physical memory Windows Vista 64-Bit Basic supports up to 8 GB of RAM, Windows Vista 64-Bit Home Premium supports up to 16 GB of RAM, and Windows Vista 64-Bit Professional/Enterprise/Ultimate supports up to 128 GB of RAM.
With its unique features, Windows Vista partitions are often difficult to handle. Most partition software cannot work under Windows Vista environment. Fortunately, MiniTool Partition Manager, developed by Mt Solution, is the best partition manager for Windows Vista partitions.
First, launch the software and you will see its user friendly interface.
The property of each partition is clearly displayed.
Second, select the partition you want to resize, then click the Move/Resize button or right click the selected partition and click Move/Resize. You will see a pop up window like below.
Here we choose to resize partition O. From the picture above, we can see partition O is 80G, while partition C is less than 30G. At the same time, we find that this disk has a large amount of free space. With the increase of applications installed, it is necessary for us to enlarge the backup partition O and the system partition C.
Next, we will resize partition O with MiniTool Partition Manager.
Enlarge partition O from 80 G to 150 G. Enlarge the whole partition by 60 G. Resize the system partition C and enlarge the partition C:
Lastly, apply changes, after that you will see:
Now, partition O and C are resized just by a few simple steps. All these processes are carried out under Enhanced Data Protection Mode, so you never have to worry about any data loss. MiniTool Partition Manager will ensure you the safety of your data.
This process would be finished under special protection mode in minutes. This entire feature will ensure the safety of your data.
MiniTool Partition Manager support both MBR and GUID partition table format running on 32/64 bits operating system, including Windows XP, Vista, Windows Server 2000/2003/2008 and the latest Windows 7.
As a professional Partition Manager, Partition Wizard can save you as much as 80% of time in partition management tasks.
