adblockThe use of ad-blocking software is growing as Internet users try to deal with the swelling number of ads delivered programmatically and the pervasive tracking of their online behavior.

This growth has set alarm bells ringing within the online advertising industry, with concerns that the use of ad blockers could damage publishers' online revenues. Just last week it emerged that two groups of publishers in France are considering a lawsuit against, Eyeo GmbH, the maker of AdBlockPlus. 

While behavioral advertising ideally makes advertising more relevant to viewers, some people find it "creepy"; data shows that last year’s revelations of the National Security Administration’s attempts to track citizens online has made them warier than ever.

If you don't have your Windows 7 disc handy—but want to create a custom installation, run Windows from a USB drive, or just do a fresh install—you'll need an ISO file of the disc. You used to be able to download them from Digital River's servers, but those links no longer work. Now, Microsoft has a Software Recovery Center where you can download those ISOs for free.

This isn't piracy, of course—you still need a valid Windows license to download the ISO and register Windows. If you purchased a retail version of Windows, enter the product key from the package. If you can't find it, use a program like Magical Jelly Bean KeyFinder. Once Microsoft confirms your product key, you can download Windows and use the Windows 7 USB Download Tool to put it on a thumb drive.

If your computer came with Windows, however, it's probably an OEM version, which will not work on Microsoft's new site. Instead, if you want to reinstall Windows without the bloatware, you'll probably need to borrow a disc from someone and use your product key when you resinstall.

Windows 8.1 users have always been able to download ISOs with Microsoft's tool, which you can now get here.

internet explorerWhile Microsoft has dropped hints that the Internet Explorer brand is going away, the software maker has now confirmed that it will use a new name for its upcoming browser successor, codenamed Project Spartan. Speaking at Microsoft Convergence yesterday, Microsoft's marketing chief Chris Capossela revealed that the company is currently working on a new name and brand. "We’re right now researching what the new brand, or the new name, for our browser should be in Windows 10," said Capossela. "We’ll continue to have Internet Explorer, but we’ll also have a new browser called Project Spartan, which is codenamed Project Spartan. We have to name the thing."

Internet Explorer will still exist in some versions of Windows 10 mainly for enterprise compatibility, but the new Project Spartan will be named separately and will be the primary way for Windows 10 users to access the web. Microsoft has tried, unsuccessfully, to shake off the negative image of Internet Explorer over the past several years with a series of amusing campaigns mocking Internet Explorer 6. The ads didn't improve the situation, and Microsoft's former Internet Explorer chief left the company in December, signalling a new era for the browser.

windowsWindows 10 will be a free upgrade for Windows 7 and Windows 8 users this summer, but Microsoft is also extending its offer to software pirates. "We are upgrading all qualified PCs, genuine and non-genuine, to Windows 10," says Terry Myerson, Microsoft’s Windows chief, in an interview with Reuters. The move means that thousands, perhaps millions, of machines will get a free copy of Windows 10 even if a license has not been properly acquired. "Anyone with a qualified device can upgrade to Windows 10, including those with pirated copies of Windows," says a Microsoft spokesperson in a statement to The Verge. "We believe customers over time will realize the value of properly licensing Windows and we will make it easy for them to move to legitimate copies."

If you recently installed or updated uTorrent on your PC, you may have have picked up an unwanted passenger: a bitcoin miner called Epic Scale. If you don't pay attention, that piece of code can be inadvertently installed with the latest uTorrent build (version 3.4.2). It can then use your computer as part of a bitcoin farm (Litecoin, to be exact) to generate revenue for third parties. Users first reported the situation on uTorrent's forums, and it was quickly confirmed by a senior support manager. He said that the app "cannot be installed without permission," but one user claimed that there was "never a warning about it," even though he opted out of other bundled software.

Lenovo bagged a paltry US$250,000 from the deal that saw it install the Superfish certificate slurper onto PCs, according to reports.

The PC maker was last month caught installing the ad/bloat/malware into its consumer PCs, sparking a very considerable backlash once the software's ability to intercept encrypted website communications was revealed.

Forbes sources' now say Lenovo made between US$200,000 to US$250,000 from the deal to pre-install Superfish, a paltry amount given its net profit was US$253 million in the three months to December.

At $250,000 the return on investment for Superfish is abominable: Lenovo initially defended the installation as a helpful tool for online shoppers, but quickly back-pedalled and started wheeling out senior execs at all hours of day and night to make apologetic utterances.

googleCAPTCHAs are an unfortunate side effect of the internet. They're those irritating collection of numbers and letters morphed into some Surrealist dreck that leaves us guessing, and guessing, and guessing. Google wants to improve all of that with updates to reCAPTCHA, a one-click solution for telling websites that you are, in fact, a human being.

Wouldn't abandoning those Dali-like distortions defeat the purpose of protecting websites from bots? Not really, Google says, because the old CAPTCHA system wasn't working that great anyways:

While the new reCAPTCHA API may sound simple, there is a high degree of sophistication behind that modest checkbox. CAPTCHAs have long relied on the inability of robots to solve distorted text. However, our research recently showed that today's Artificial Intelligence technology can solve even the most difficult variant of distorted text at 99.8% accuracy. Thus distorted text, on its own, is no longer a dependable test.

There has been a LOT of confusion around Windows, SSDs (hard drives), and whether or not they are getting automatically defragmented by automatic maintenance tasks in Windows.

There's a general rule of thumb or statement that "defragging an SSD is always a bad idea." I think we can agree we've all heard this before. We've all been told that SSDs don't last forever and when they die, they just poof and die. SSDs can only handle a finite number of writes before things start going bad. This is of course true of regular spinning rust hard drives, but the conventional wisdom around SSDs is to avoid writes that are perceived as unnecessary.

Does Windows really defrag your SSD?

I've seen statements around the web like this:

I just noticed that the defragsvc is hammering the internal disk on my machine.  To my understanding defrag provides no value add on an SSD and so is disabled by default when the installer determines the disk is SSD.  I was thinking it could be TRIM working, but I thought that was internal to the SSD and so the OS wouldn’t even see the IO.

One of the most popular blog posts on the topic of defrag and SSDs under Windows is by Vadim Sterkin. Vadim's analysis has a lot going on. He can see that defrag is doing something, but it's not clear why, how, or for how long. What's the real story? Something is clearly running, but what is it doing and why?

I made some inquiries internally, got what I thought was a definitive answer and waded in with a comment. However, my comment, while declarative, was wrong.

Windows doesn’t defrag SSDs. Full stop. If it reports as an SSD it doesn’t get defraged, no matter what. This is just a no-op message. There’s no bug here, sorry. - Me in the Past

I dug deeper and talked to developers on the Windows storage team and this post is written in conjunction with them to answer the question, once and for all

"What's the deal with SSDs, Windows and Defrag, and more importantly, is Windows doing the RIGHT THING?"

It turns out that the answer is more nuanced than just yes or no, as is common with technical questions.

The short answer is, yes, Windows does sometimes defragment SSDs, yes, it's important to intelligently and appropriately defrag SSDs, and yes, Windows is smart about how it treats your SSD.

The long answer is this.

Actually Scott and Vadim are both wrong. Storage Optimizer will defrag an SSD once a month if volume snapshots are enabled. This is by design and necessary due to slow volsnap copy on write performance on fragmented SSD volumes. It’s also somewhat of a misconception that fragmentation is not a problem on SSDs. If an SSD gets too fragmented you can hit maximum file fragmentation (when the metadata can’t represent any more file fragments) which will result in errors when you try to write/extend a file. Furthermore, more file fragments means more metadata to process while reading/writing a file, which can lead to slower performance.

As far as Retrim is concerned, this command should run on the schedule specified in the dfrgui UI. Retrim is necessary because of the way TRIM is processed in the file systems. Due to the varying performance of hardware responding to TRIM, TRIM is processed asynchronously by the file system. When a file is deleted or space is otherwise freed, the file system queues the trim request to be processed. To limit the peek resource usage this queue may only grow to a maximum number of trim requests. If the queue is of max size, incoming TRIM requests may be dropped. This is okay because we will periodically come through and do a Retrim with Storage Optimizer. The Retrim is done at a granularity that should avoid hitting the maximum TRIM request queue size where TRIMs are dropped.

Wow, that's awesome and dense. Let's tease it apart a little.

When he says volume snapshots or "volsnap" he means the Volume Shadow Copy system in Windows. This is used and enabled by Windows System Restore when it takes a snapshot of your system and saves it so you can rollback to a previous system state. I used this just yesterday when I install a bad driver. A bit of advanced info here - Defrag will only run on your SSD if volsnap is turned on, and volsnap is turned on by System Restore as one needs the other. You could turn off System Restore if you want, but that turns off a pretty important safety net for Windows.

One developer added this comment, which I think is right on.

I think the major misconception is that most people have a very outdated model of disk\file layout, and how SSDs work.

First, yes, your SSD will get intelligently defragmented once a month. Fragmentation, while less of a performance problem on SSDs vs traditional hard drives is still a problem. SSDS *do* get fragmented.

It's also worth pointing out that what we (old-timers) think about as "defrag.exe" as a UI is really "optimize your storage" now. It was defrag in the past and now it's a larger disk health automated system.

Fragmentation has long been considered as primarily a performance issue with traditional hard drives. When a disk gets fragmented, a singular file can exist in pieces in different locations on a physical drive. That physical drive then needs to seek around collecting pieces of the file and that takes extra time.

This kind of fragmentation still happens on SSDs, even though their performance characteristics are very different. The file systems metadata keeps track of fragments and can only keep track of so many. Defragmentation in cases like this is not only useful, but absolutely needed.

SSDs also have the concept of TRIM. While TRIM (retrim) is a separate concept from fragmentation, it is still handled by the Windows Storage Optimizer subsystem and the schedule is managed by the same UI from the User's perspective. TRIM is a way for SSDs to mark data blocks as being not in use. Writing to empty blocks on an SSD is faster that writing to blocks in use as those need to be erased before writing to them again. SSDs internally work very differently from traditional hard drives and don't usually know what sectors are in use and what is free space. Deleting something means marking it as not in use. TRIM lets the operating system notify the SSD that a page is no longer in use and this hint gives the SSD more information which results in fewer writes, and theoretically longer operating life. 

In the old days, you would sometimes be told by power users to run this at the command line to see if TRIM was enabled for your SSD. A zero result indicates it is.

However, this stuff is handled by Windows today in 2014, and you can trust that it's "doing the right thing." Windows 7, along with 8 and 8.1 come with appropriate and intelligent defaults and you don't need to change them for optimal disk performance. This is also true with Server SKUs like Windows Server 2008R2 and later.


No, Windows is not foolishly or blindly running a defrag on your SSD every night, and no, Windows defrag isn't shortening the life of your SSD unnecessarily. Modern SSDs don't work the same way that we are used to with traditional hard drives.

Yes, your SSD's file system sometimes needs a kind of defragmentation and that's handled by Windows, monthly by default, when appropriate. The intent is to maximize performance and a long life. If you disable defragmentation completely, you are taking a risk that your filesystem metadata could reach maximum fragmentation and get you potentially in trouble.
