Most home users don’t know (or care) about Trim, but Trim support is something like the Holy Grail for commercial computing. Trim is a command that allows an operating system to mark blocks on solid-state drives (SSD) for cleaning and re-use. Doesn’t sound exciting yet? Without Trim, using solid-state drives in Redundant Array of Independent Disks (RAID) arrays becomes very hard because blocks that could be used can’t be easily identified, and in the end, the performance of the entire setup suffers. Intel has just indicated that it plans to offer Trim support in an upcoming Intel driver release.

Not The First Time Trim Support Has Been Announced

Keep in mind that this isn’t an official announcement for Trim support, and also keep in mind that we were led to believe that Trim support would be introduced in 2009. With that having been said, getting real Trim support could make life a lot less complicated for users who rely on RAID 0 storage schemes for data.

Home users aren’t likely to be impacted at all by the addition of Trim support, but enterprise users will welcome the ability to include SSD in RAID storage arrays. SSDs offer some big advantages over their traditional counterparts in terms of space, cost and reliability, but not being able to make efficient use of space has been a serious downer.

The changes, according to Intel, will be released in the 11.5 version of Intel’s Alpha Rapid Storage Technology (RST) driver. The next release is version 11.0, so Trim support is still on the horizon. The ability to support RAID 0 is the first step toward extending support to RAID 1 and RAID 5 setups.
Windows 7 already supports Trim for SSDs, but that support doesn’t extend to RAID arrays. In other words, Trim works on single SSDs in Windows 7, but not in storage arrays. Intel hasn’t provided a timetable for the release of its version 11.5 RST drivers, but the support will be welcome whenever it comes.

Currently, without Trim support, the performance of SSD arrays over time seriously degrades as storage disks become filled with data. Without the ability to identify disk blocks that can be wiped and re-used, the user effectively has no way to defragment an SSD RAID array. Any user who has worked on a badly fragmented drive will immediately understand the implications of that!

Microsoft announced last week that Windows 8 will not be a distribution channel for third-party application updates. The statement doesn’t change the current arrangement for (read: Windows driver updates ) in its regular “Patch Tuesday” loads. Some users had been hoping that Microsoft would tackle the responsibility of delivering application updates through a single, uniform updater tool, provided by Microsoft through the OS. Microsoft put the kibosh on that, saying that application updating is just too darned complicated.

Change Means That Third-Parties Are On Their Own For Distributions

This doesn’t change things for Windows driver updates, however, not all third-party manufacturers update their drivers through the Windows Update feature. The change in policy for Windows 8 means that users will have to remain on duty when it comes to keeping their Windows applications up-to-date.

In terms of device drivers, the status quo doesn’t guarantee that users have the latest device drivers, and that’s going to continue in Windows 8. Right now, the experience of updating device drivers is a mixed bag. With some third parties participating in Windows Update and others doing their own thing, users need to keep track of what’s being updated regularly and what isn’t.

For busy users, or for those who are not technically savvy, a better approach to driver maintenance is using a driver management utility like Driver Detective. Driver Detective determines – based on your computer system – what driver updates you need and downloads them right to your computer. The updates are installed and a backup copy of the current driver is stored locally, in case something happens to the active copy. You can also roll back to an older version of the driver if a new driver update doesn’t behave the way you think it should.

You don’t have to remember to check for updates. Driver Detective does that for you. You also don’t have to keep track of a lot of hardware configuration information, because Driver Detective does that, too! This is ideal for manufactures that use multiple third party component options within a single model. Driver Detective determines what your system needs – not based on the model number of your computer – but based on the components actually installed in your system. If you update a video card, add a different mouse, or attach a new peripheral device, Driver Detective can track and maintain those devices, too.

Driver Detective is one of the best driver management utilities available today. Millions of users have already downloaded it and rely on it to keep their computer systems up to date. Download your copy today and say goodbye to outdated device driver problems!

It’s hard to believe, but your Windows device drivers can have a profound effect on the battery performance of your laptop computer. How? As it turns out, the decision to enable or disable power management features at the device driver level can significantly improve or diminish your battery life.

Laptops Are Meant To Use Low Power

Laptops are meant to use low power, and that sometimes means making adjustments to the way devices consume power. When you do a driver install and you just do the default configuration, (as most users do – because it’s the “safest” installation, right?) most often, you’re guaranteeing that your battery life will be short. Why? In the absence of any other configuration, the default firmware initialization for most devices calls for the highest available power. If all of your laptop devices use high power, your battery life will definitely suffer. Select devices in high power mode can reduce your battery life by as much as 25%!

The default configuration can’t possibly take into account what your actual power usage needs are, so it assumes the worst and makes as much power as possible available to a device. On a desktop computer, power management is generally not a consideration. On a laptop, where the manufacturers have already made compromises on the chipsets, the maximum memory capacity and the processor speed, these concessions must extend through to your devices as well.

If you’re not in a situation where you need your wireless mouse, or your network card, you can manage the power consumption of these devices much more effectively, and ensure that you have enough battery life to get your work done.

Doing power management via the device driver also means having the most recent device driver loaded. Manufacturers often tweak their driver-level power management capabilities, and the only way to take advantage of this is to make sure you have the most recent device driver for your computer.

With Windows, you can’t always be certain that Microsoft will pass through device driver updates to you. That has nothing to do with Microsoft; some third-party developers don’t give their driver updates to Microsoft. For those devices, it’s up to you to go out and get the latest driver updates – or at least check regularly for them.

That’s why I recommend Driver Detective. Driver Detective takes the guesswork out of device driver maintenance. It’s highly reliable and helps to ensure that you’ll always have the drivers your computer needs.

A Windows kernel driver vulnerability got no love from Microsoft on Patch Tuesday this week. Microsoft did fix a host of important vulnerabilities, but the Duqu hack was as yet untouched in a permanent way. That’s not to say that Microsoft has done nothing about Duqu. If you were paying attention to your updates last week, you’ll know that Microsoft zinged out a little stinger designed to help vulnerable systems dodge the Duqu bullet. The little fix simply eliminates access to T2EMBED.DLL, a dynamic linked library used to display True Type fonts.

Expect Duqu Fix Soon

What exactly is Duqu? It’s a computer worm that is thought to be related to last year’s Stuxnet. In fact, Duqu is somewhat like Stuxnet in that it is a zero-day vulnerability – meaning that malefactors discovered and exploited the flaw before Microsoft knew about it. An infected Microsoft Word .doc file that contains the malicious code delivers Duqu. Duqu accesses the vulnerable library and gains access to kernel mode operations. This enables the worm to run arbitrary code that can install other programs, create new user accounts and access or change stored data. Microsoft has said that it is actively seeking a permanent fix to the Duqu exploit. Duqu also uses a stolen digital certificate pinched from C-Media in Taiwan.

Another exploit Microsoft did fix on Patch Tuesday involved TrueType fonts, but wasn’t related to Duqu. The patch for this potential DOS attack does not change the Duqu vulnerability at all. This particular vulnerability would have limited ability to affect users, and would require some significant effort on the part of the user in order to be successful.

Patch Tuesday did clean up four vulnerabilities that Microsoft says could have supported an exploit that would run arbitrary code on a vulnerable computer. In addition, Microsoft repaired a few “theoretical” problems that had the potential to put network users at some level of risk. The new patches change the way Windows handles and tracks UDP packets, but Microsoft stressed that these driver vulnerabilities were never actually exploited. The company also cast some doubt on whether the vulnerabilities could lead to an exploit.

Most of the vulnerabilities repaired in the Patch Tuesday release were aimed at the newer versions of Windows, including Windows Vista, Windows 7 and Windows Server 2008. Keep an eye out for a fix for Duqu. While Microsoft does tend to reserve updates for Patch Tuesday, they usually offer a low-key Patch Tuesday on the fourth Tuesday of the month, and they always reserve the right to send out-of-band updates whenever the risk justifies an instant update.
