What is the difference between Microsoft and Windows?

Windows Time Service Registry Entries

When my computer crashes and I get it serviced at a computer shop, does that mean I lose ALL information on my computer?

Memory and Address Space Limits

Computer names are separated by commas, with no spaces. The default value is 3. Allowed range is Tells a computer that it should resynchronize its clock as soon as possible, throwing out all accumulated error statistics. If not specified, the local computer will resynchronize. Otherwise, wait for the resynchronize to complete before returning. Not useful, provided for compatibility.

Display a strip chart of the offset between this computer and another computer. The default is 2s. If not specified, the default is the local computer.

When specifying multiple peers, this option must be enclosed in quotes. YES NO - set whether this computer is a reliable time source. This setting is only meaningful on domain controllers. YES - this computer is a reliable time service. NO - this computer is not a reliable time service. Display the values associated with a given registry key.

This parameter was first made available in the Windows Time client versions of Windows Vista, and Windows Server Display a computer's Windows Time service information. If not specified, the default value is the local computer. Source - Display the time source. Configuration - Display the configuration of run time and where the setting comes from. In verbose mode, display the undefined or unused setting too.

Enable or disable the local computer Windows Time service private log. Valid numbers are 0 to A range of numbers is valid, in addition to single numbers, such as ,, Value is for logging all information. Entry indicates that non-standard mode combinations are allowed in synchronization between peers. Entry specifies a space-delimited list of peers from which a computer obtains time stamps, consisting of one or more DNS names or IP addresses per line.

Computers connected to a domain must synchronize with a more reliable time source, such as the official U. The default value on stand-alone clients and servers is time. Entry is maintained by W32Time. It contains reserved data that is used by the Windows operating system, and any changes to this setting can cause unpredictable results. Entry indicates which peers to accept synchronization from: The time service does not synchronize with other sources.

The time service synchronizes from the servers specified in the NtpServer. The time service synchronizes from the domain hierarchy. The time service uses all the available synchronization mechanisms.

The default value on domain members is NT5DS. The default value on stand-alone clients and servers is NTP. Entry controls whether this computer is marked as a reliable time server. A computer is not marked as reliable unless it is also marked as a time server. The default value for stand-alone clients and servers is Entry controls the events that the time service logs.

The default value on stand-alone clients and servers is 2. Entry controls the rate at which the clock is corrected. If this value is too small, the clock is unstable and overcorrects. If the value is too large, the clock takes a long time to synchronize. The default value on domain members is 4. The default value on stand-alone clients and servers is 4. Note that 0 is an invalid value for the FrequencyCorrectRate registry entry.

Entry controls the period of time for which spike detection is disabled in order to bring the local clock into synchronization quickly. A spike is a time sample indicating that time is off a number of seconds, and is usually received after good time samples have been returned consistently. The default value on domain members is 5. The default value on stand-alone clients and servers is 5.

Entry specifies that a time offset greater than or equal to this value in 10 -7 seconds is considered a spike. A network disruption such as a large amount of traffic might cause a spike. A spike will be ignored unless it persists for a long period of time. Entry controls the dispersion in seconds that you must assume when the only time source is the built-in CMOS clock. Entry specifies the maximum offset in seconds for which W32Time attempts to adjust the computer clock by using the clock rate.

When the offset exceeds this rate, W32Time sets the computer clock directly. The default value for domain members is See below for more information. Entry specifies the largest negative time correction in seconds that the service makes.

If the service determines that a change larger than this is required, it logs an event instead. The default value for stand-alone clients and servers is 54, 15 hrs. For more information, see What is 4GT. Limits on physical memory for bit platforms also depend on the Physical Address Extension PAE , which allows bit Windows systems to use more than 4 GB of physical memory.

The following table specifies the limits on memory and address space for supported releases of Windows. Unless otherwise noted, the limits in this table apply to all supported releases. If the memory is remapped, X64 Windows can use this memory. Any X64 Windows or X86 Server release can. The limit that these versions impose is the highest permitted physical RAM address, not the size of the IO space.

Putting together Nokia's smartphone hardware and Microsoft's software and marketing power seemed to be a reasonable bet, but it was by no means a certain one. But the phones' hardware and software was not the problem: Nokia's long history of creating elegant hardware meant that the Lumias won plaudits for smart design.

And, after a few false starts, Windows Phone with its tiled user interface seemed far cooler than iOS. Nonetheless, together, they just didn't sell enough phones.

In its best-ever quarter Microsoft managed to sell To put those numbers into context, Apple sold 61 million iPhones in its most recent quarter. For Microsoft, that's just nowhere near good enough. Partly that was because Android and iOS were well entrenched by the time Windows Phone had matured, but also because Windows Phone has never built up the same app ecosystem the other two operating systems did. This meant that some top apps would not arrive on Windows Phone for a long time, if they ever arrived at all.

Microsoft's mobile strategy has at times been hard to fathom too. It has favoured a scattergun approach, launching an array of different smartphones and then waiting to see which ones find favour - in contrast to the measured approach of Apple. Lumias found most of their success at the entry level.

Indeed, there hasn't really been a 'flagship' Lumia a clear top of the range device released for a while. In the meantime, Microsoft has been experimenting with putting its services onto iOS and Android devices instead Nokia even testing out an Android device which may have given some customers one less reason to buy its hardware.

Why is Windows Phone outselling the iPhone in Poland? Poland was one of seven countries Microsoft named where Windows Phone is more popular than Apple's iPhone. A mixture of brand perception, operator support and good, old-fashioned pricing. Microsoft is, it appears, aiming to be device-agnostic here: It's not a terrible strategy but at the moment consumers still prefer those services on handsets that aren't made by Microsoft. The benefit of making your own hardware is that you can tightly embed your own software and services, making them the default options.

When you are piggybacking on someone else's operating system, those close ties are much harder to achieve.
