How to Use Windows 10's Storage Spaces to Mirror and Combine Drives

Le 28 septembre 2017, 06:21 dans Humeurs 0

The Storage Spaces feature built into Windows allows you to combine multiple hard drives into a single virtual drive. It can mirror data across multiple drives for redundancy, or combine multiple physical drives into a single pool of storage. Storage Spaces is similar to RAID or LVM on Linux.

This feature was added in Windows 8, and was improved in Windows 10. It's available on all editions of Windows 8 and 10, including Home editions.

What Are Storage Spaces?

To create a Storage Space, you need at least two physical drives on your PC. These can be internal drives or external drives connected via USB.

Storage Spaces allow you to create a "storage pool" of two or more physical drives, grouping them together. Once you've created a storage pool made up of two or more physical drives, you can create three types of "spaces" using that pool:

A simple space is designed to give you the most storage possible, but doesn't provide any protection against drive failure. Windows will store only a single copy of your data across all the drives. If one of these drives fails, your data will be lost and corrupted. This is ideal for temporary data.

A mirror space is designed to protect you from drive failure by storing multiple copies of your files. A single drive-or more than one drive, depending on how you configure things-can fail and you won't lose any data. This is ideal for protecting important data from hardware failure.

A parity space is designed as a compromise. Windows will keep a single copy of your data along with parity information. You'll have more space and you'll be protected if a single drive fails. However, parity spaces are slower than simple and mirror spaces. This solution is ideal for data archival, and not data you use frequently.

If you choose to format a mirror or parity space with the Windows Resilient File System (ReFS), Windows will automatically monitor and maintain file integrity to prevent file corruption.

How to Create a Storage Space

You can create a Storage Space from the Control Panel. First, connect the drives you want to group together to your computer. Then, head to Control Panel > System and Security > Storage Spaces. You can also just search for "Storage Spaces" in your Start menu.

Click the "Create a new pool and storage space" link to get started.

To test this, you'll have to get your computer's software fixed for your windows 10. If you're lucky, one of these steps may fix your software problem and allow you to boot Windows normally. If you can not find the previous activation code, you can click softkeyhome to buy genuine windows product key with the lowest price.

Select the drives you want to add to the pool and click "Create Pool" to create a storage pool from those drives.

Warning: All data on the drives you select will be erased, so back up any important data before continuing!

After creating a pool, you'll be prompted to configure your new storage space. Type a name for the storage space and select a drive letter. The storage space will appear with this name and drive letter in Windows.

You can select either the standard Windows NTFS file system or ReFS, the new resilient file system. If you'll be using mirroring or parity to protect against data loss, we recommend choosing ReFS for its file integrity protection features.

You'll need to choose a resiliency type. Select "Simple (no resiliency)" for a large pool of storage that provides no protection from drive failure. Select "Two-way mirror" to store two copies of your data across the drives or select "Three-way mirror" to store three copies of your data across the drives. Select "Parity" to be protected from a single drive failure and have more space, but remember that a parity space is noticeably slower than the other options here.

You'll also need to choose the size of your storage space here. The interface will show you the maximum available amount of storage you have, which will vary depending on the type of space you create.

This interface allows you to create pools of storage larger than the amount of physical storage space you have available. When the physical storage fills up, you can plug in another drive and take advantage of it with no additional configuration required.

Click "Create storage space" when you're done configuring your storage space.

How to Use Storage Spaces

The storage space you created will appear as a standard drive under This PC, with the name and drive letter you configured. It appears no different from a normal, physical drive to Windows and the desktop programs you use.

You can do anything you'd do with a normal drive with the storage space. For example, you can even enable BitLocker drive encryption for it.

What Is Memory Compression in Windows 10?

Le 25 septembre 2017, 08:33 dans Humeurs 0

Windows 10 uses memory compression to store more data in your system's memory than it otherwise could. If you visit the Task Manager and look at your memory usage details, you'll likely see that some of your memory is "compressed". Here's what that means.

What Is Memory Compression?

Memory compression is a new feature in Windows 10, and is not available on Windows 7 and 8. However, both Linux and Apple's macOS also use memory compression.

What Is the Windows Page File, and Should You Disable It? Traditionally, if you had 8 GB of RAM and applications had 9 GB of stuff to store in that RAM, at least 1 GB would have to be "paged out" and stored in the page file on your computer's disk. Accessing data in the page file is very slow compared to RAM.

With memory compression, some of that 9 GB of data can be compressed (just like a Zip file or other compressed data can be shrunk down) and kept in RAM. For example, you might have 6 GB of uncompressed data and 3 GB of compressed data that actually takes up 1.5 GB in RAM. You'd be storing all 9 GB of the original data in your 8 GB of RAM, as it would only take up 7.5 GB once some of it was compressed.

Is there a downside? Well, yes and no. Compressing and uncompressing the data takes some CPU resources, which is why not all data is stored compressed-it's only compressed when Windows thinks it's necessary and helpful. Compressing and uncompressing the data at the cost of some CPU time is much, much faster than paging the data out to disk and reading it from the page file, though, so it's usually worth the tradeoff.

Is Compressed Memory Bad?

Compressing data in memory is much better than the alternative, which is paging that data out to disk. It's faster than using the page file. There's no downside to compressed memory. Windows will automatically compress data in memory when it needs space, and you don't need even to think about this feature.

But memory compression does use some CPU resources. Your system may not perform as fast as it would if it didn't need to compress data in memory in the first place. If you see a lot of compressed memory and suspect it's the reason your PC is a bit slow, the only solution for this is installing more physical memory (RAM) in your system. If your PC doesn't have enough physical memory for the applications you use, memory compression is better than the page file-but more physical memory is the best solution.

How to View Compressed Memory Details on Your PC

To view information about how much memory is compressed on your system, you'll need to use the Task Manager. To open it, either right-click your taskbar and select "Task Manager", press Ctrl+Shift+Esc, or press Ctrl+Alt+Delete and then click "Task Manager"

If you are experiencing any problems with Windows 10, then Microsoft urges you to use the Feedback Hub to submit complaints or search for possible similar cases that may have been resolved. If need some help you can check goodkeyhome to find windows product key online with the lowest price. If you see the simple Task Manager interface, click the "More details" option at the bottom of the window.

Click the "Performance" tab and select "Memory". You'll see how much memory is compressed under "In use (Compressed)". For example, in the screenshot below, the Task Manager shows that our system is currently using 5.6 GB of its physical memory. 425 MB of that 5.6 GB is compressed memory.

You'll see this number fluctuate over time as you open and close applications. It will also just fluctuate as the system does work in the background, so it'll change as you stare at the window here.

If you mouse over the the left-most part of the bar under Memory composition, you'll see more details about your compressed memory. In the screenshot below, we see that our system is using 5.7 GB of its physical memory. 440 MB of this is compressed memory, and this compressed memory stores an estimated 1.5 GB of data that would otherwise be stored uncompressed. This results in a 1.1 GB memory savings. Without memory compression, our system would have 6.8 GB of memory in use rather than 5.7 GB.


Does This Make the System Process Use a Lot of Memory?

In the original release of Windows 10, the "compression store" was stored in the System process and was "the reason the System process appears to be consuming more memory than previous releases", according to a Microsoft blog post.

However, at some point, Microsoft changed the way this works. Compressed memory is no longer displayed as part of the System process in the Task Manager (probably because it was very confusing to users). Instead, it's visible under Memory details on the Performance tab.

On Windows 10's Creators Update, we can confirm that compressed memory is only displayed under Memory details, and the System process stays at 0.1 MB of usage on our system even when the system has a lot of compressed memory. This saves confusion, as people won't wonder why their System process is mysteriously using so much memory.

Windows 10 troubleshooting tools

Le 21 septembre 2017, 07:54 dans Humeurs 0

You can find all tools in the troubleshooting widget of the control panel. To get to it, type "troubleshoot" in the search box and then, choose the "View all" option. This is what you'll see:

If you're thinking that this list is similar to the one found in Windows 8.1, you're absolutely right. However, there are five features in Windows 10 that can make a huge difference in terms of performance.

New troubleshooting features in Windows 10

Here are the five important troubleshooting tools you can find in Windows 10:

Background Intelligent Transfer Service

Background Intelligent Transfer Service, also known as BITS, is used to transfer files asynchronously between a client and a server. Though it is present in Windows 8, too, the latest version is available only in Windows 10, and it comes with the following new features:

If you are experiencing any problems with Windows 10, then Microsoft urges you to use the Feedback Hub to submit complaints or search for possible similar cases that may have been resolved. If need some help you can check softkeyhome to find windows product key online with the lowest price.

You can now use BITS COM APIs and BITS PowerShell cmdlets in a remote PowerShell session. This is particularly useful for long-running transfers.

It allows owners to set helper tokens, even if the user is not an administrator. This reduces the problems and vulnerabilities that come with background download, as it allows even a lower-privileged account to have control over downloads. This way, administrative privileges can be protected for more critical operations.

Blue Screen

As a PC user, you'll never want to see a blue screen, as this simply means your PC has crashed. In Windows 10, a Blue Screen troubleshooting tool has the capability to go through the dumps generated when your PC crashes, and provide possible pointers and fixes, like the message below:

Keyboard issues

As frustrating as it may sound, keyboard issues are a staple for PC users. The good news is the keyboard troubleshooter can get misconfigured keyboards to work again within a short time. Ironically, this tool has a typo in its description as it reads "comupter's keyboard settings!"

Speech troubleshooter

Cortana, the virtual helper, is an essential part of Windows 10. However, its functionality is lost when there are issues with speech recognition. If you encounter such problems, try the speech troubleshooter as it checks if the microphone is connected to the PC and if it is configured correctly for speech recognition.

Windows Store

Another unique feature of Windows 10 is Windows Store, an online area that allows you to download hundreds of free and paid apps. There are some troubleshooting apps available here.
