Windows Vista computers that come equipped with more than 4 GB of system memory have limited shut-down options. Essentially, the Hibernate option is no longer available on Vista machines that feature in excess of 4 GB of RAM. This scenario affects both the 32-bit and the 64-bit editions of Vista, but at the same time also Windows XP and Windows Server 2003. Microsoft has confirmed that the issue is related to the large quantity of random access memory.
“This issue occurs because hibernation is disabled on computers that have more than 4 GB of RAM. Hibernation requires sufficient disk space to contain the contents of the computer’s memory. Performance is poor on a computer that has more than 4 GB of memory and that has support for hibernation. (more…)

Managing PC memory isn’t as big an issue as it used to be, but freeing up memory can still provide benefits. Rather than spending a lot of time closing old processes, installing Instant Memory Cleaner is a quick solution.
Once installed, this tiny app (and it really is tiny at 1.8MB) sits in your system tray and if you hover your mouse, it will tell you how much memory is available. To free up memory all you have to do is right click on the icon and select ‘Clean Memory’. Within seconds your PC will have more memory available, which will make all those resource hungry apps you run, move along that little bit faster. (more…)

When it comes down to the 32-bit Windows Vista vs. 64-bit Windows Vista, the comparison generally focuses on the added benefits synonymous with handling system memory. Because the address space of 64-bit Vista is not limited to 4GB, users are able to use a maximum of 128 GB of RAM with the Ultimate, Business and Enterprise SKUS. But at the same time, there are added benefits, and one of them is in terms of security. The 64-bit editions of Vista come to the table with PatchGuard (Kernel Patch Protection), Address Space Layout Randomization (ASLR), Heap and Stack randomization, and even heap corruption detection.
As far as Heap Based Buffer Overruns are concerned, both 32-bit and 64-bit Vista offer protection, but only in the x64 versions of the operating system is the even heap corruption detection enabled by default. Michael Howard, Senior Security Program Manager in the Security Engineering group at Microsoft, explained that, in x86 Vista, software developers have to call the HeapSetInformation API in order to enable heal corruption detection.

Too much Windows Vista cache, a bad ting? Well, apparently yes, through Excessive Cached Write I/O and Excessive Cached Read I/O. As you probably know by now, cache is connected with boosting the performance of data accessing processes that target sluggish storage media. In an ideal scenario, the data or the code pages would be completely located within the system memory. The speed at which data is accessed, in the physical RAM, exceeds by far that of similar processes that involve a hard disk, by approximately 1 million times. But, because of the usually limited amount of RAM, the operating system will have to deal with system cache. (more…)

We’ve filtered and sorted through the hundreds of Vista hints and tweaks to find the ones that we think the most readers will find useful. While Vista still feels new, these hints and tweaks might help you settle into your OS.
Introduction
So you’ve installed Vista, perhaps against your better judgment, and now you’re wondering what you can do to spruce it up a bit. We’re right there with you, and have poured over the Web looking for the coolest, most-useful tweaks we could find. We searched high and low, and completed this list of tweaks so that you did not have to. We have personally tested all of these tweaks and employ most of them on our own systems. (more…)

Windows XP contains several tweakable memory settings in the registry, one of which is the DisablePagingExecutive registry key. This controls whether the operating system will transfer its essential driver and kernel files to the ‘virtual memory’ (the page file on the hard disk). It defaults to allowing this.
Obviously, transferring portions of the system to hard drive memory can considerably slow things down, and it appears that Windows XP does this periodically, whether or not the system is actually low on physical memory (RAM).
If you have 256MB of system memory or more, try this registry tweak to force Windows to keep its operating data in main memory: (more…)

Few days back, I bought Windows Vista Business Upgrade the other day so I could start playing with it. Since I did not want to mess up the configuration of my current computer, I thought I would install Vista on a blank hard drive.
Sounds easy enough, after all the previous versions of Windows required you to have a legitimate copy of an older Windows operating system and simply asked for that copy during the install so they could verify upgrade compliance.
Before installing Windows Vista, I ran the Windows Vista Upgrade Advisor on my current system. As I suspected, my video card was not up to Vista standards and the 512MB of RAM was on the low end of what Vista wanted. (more…)
