Ljetno računanje vremena (DST)^{(Daylight Saving Time (DST))} , također ljetno računanje vremena^{(daylight savings time)} ili ljetno vrijeme^{(daylight time)} , a ljetno^(summertime) računanje vremena je praksa pomicanja satova tijekom toplijih mjeseci tako da mrak pada svaki dan kasnije prema satu. Ako primijetite visoku potrošnju CPU^(CPU) -a i memorije u sustavu Windows 10 kada je konfiguriran DST^{(Windows 10 when DST is configured)} , onda vam ovaj post treba pomoći. U ovom ćemo postu identificirati mogući uzrok, a zatim ponuditi odgovarajuće rješenje, kao i rješenje koje možete pokušati riješiti problem.

Pogledajmo tipičan scenarij u kojem možete naići na problem s postavkama DST -a koji uzrokuje visoku potrošnju CPU^(CPU) -a i memorije u sustavu Windows 10^{(Windows 10)} .

Imate računalo sa sustavom Windows 10 za korištenje vremenske zone u kojoj se promjene ljetnog računanja vremena ( DST ) događaju u ponoć (00:00) umjesto u 2:00. U ovoj situaciji možete naići na sljedeće probleme.

1. problem^{(Issue 1)}
Proces TaskHostw.exe troši 100 posto CPU resursa. Stoga se performanse sustava^{(system performance)} i trajanje baterije^{(battery life decrease)} dramatično smanjuju. Na uređajima s malim faktorom oblika, ovaj problem može utjecati na upravljanje toplinom, budući da se proces nastavlja raditi u petlji radeći izračune pretvorbe vremena.

2. problem^{(Issue 2)}
Datoteka stranice^(pagefile) troši prekomjerne resurse diska, što pokreće visoku iskorištenost diska .

Problem 3 Događa se ^{(Issue 3)}
prekomjerna upotreba memorije^{(Excessive memory use)} .

Problem 4. ^{(Issue 4)}
Prekomjerna upotreba diska, CPU-a ili memorije^{(Excessive disk, CPU, or memory use)} uzrokuje da računalo visi ili se zamrzne.

Postavka ljetnog računanja vremena^{(Daylight Saving Time)} uzrokuje veliku potrošnju CPU^(CPU) -a i memorije

Ovaj problem s postavkom ljetnog računanja vremena (DST) uzrokuje veliku upotrebu CPU-a i memorije^{(high CPU & memory usage)(Daylight Saving Time (DST) setting causes high CPU & memory usage)} u sustavu Windows 10^{(Windows 10)} nastaje zbog uvjeta utrke u procesu TaskHostW.exe^{(TaskHostW.exe process)}  (generički host proces za Windows usluge) koji pokreće jedan od zakazanih zadataka energy.dll . Ovaj zakazani zadatak izvodi se^{(scheduled task runs)} prema vremenu koje je postavljeno na računalu. Ovaj problem se javlja samo na dan kada se DST promijeni.

Datoteka energy.dll učitava se kada dođe do promjene zimskog vremena u ponoć umjesto u 2:00 ujutro .^(DST)

Ako ste suočeni s ovim problemom, možete isprobati naše preporučeno rješenje ili zaobilazno rješenje (prema vašim zahtjevima) opisano u nastavku kako biste ublažili problem.

Da biste riješili ovaj problem^{(resolve this issue)} , nadogradite svoje računalo na najnoviju verziju sustava Windows 10 .

Ako iz jednog ili drugog razloga želite ostati na trenutačnoj instalaciji sustava Windows 10^{(Windows 10)} i ne vršiti nadogradnju ili nadogradnju na najnoviju verziju sustava Windows 10 ili već koristite najnoviju verziju sustava Windows 10 , ali problem nije riješen možete isprobati rješenje koje se nudi u nastavku.

Da biste zaobišli problem^{(work around the issue)} , morate onemogućiti zadatak dijagnostike energetske učinkovitosti^{(disable the Power Efficiency Diagnostics task)} pomoću jedne od sljedećih metoda.

1. Koristite korisničko sučelje Planera zadataka^{(Task Scheduler UI)} ( korisničko sučelje^{(User Interface)} )
2. Koristite naredbeni redak

Pogledajmo opis koraka jer se odnosi na svaku od metoda za rješavanje DST postavke koja uzrokuje veliku potrošnju CPU^(CPU) -a i memorije u sustavu Windows 10^{(Windows 10)} .

1] Koristite^(Use) korisničko sučelje Planera zadataka^{(Task Scheduler UI)} ( korisničko sučelje^{(User Interface)} )

Da biste pomoću Planera zadataka ^{(use the Task Scheduler)}onemogućili zadatak dijagnostike energetske učinkovitosti, ^{(disable the Power Efficiency Diagnostics task, )} učinite sljedeće:

• Pritisnite tipku  Windows key + R  da biste pozvali dijaloški okvir Pokreni.
• U dijaloškom okviru Pokreni upišite  taskschd.msc  i pritisnite Enter da otvorite konzolu Task Scheduler .^{(open the Task Scheduler)}
• Na konzoli Task Scheduler idite na sljedeće:

Task Scheduler Library > Windows > Power Efficiency Diagnostics

• U srednjem oknu odaberite i desnom tipkom miša kliknite  AnalyzeSystem.
• Kliknite Onemogući^(Disable) .

Možete izaći iz konzole Task Scheduler .

2] Koristite naredbeni redak

Da biste pomoću naredbenog retka^{( use the Command Prompt)} onemogućili zadatak dijagnostike energetske učinkovitosti, ^{(disable the Power Efficiency Diagnostics task, )} učinite sljedeće:

• Pritisnite tipku Windows key + R da biste pozvali dijaloški okvir Pokreni.
• U dijaloškom okviru Pokreni upišite cmd , a zatim pritisnite CTRL + SHIFT + ENTER da biste open Command Prompt in admin/elevated mode .
• U prozoru naredbenog retka kopirajte i zalijepite donju naredbu i pritisnite Enter .

schtasks /Change /TN "\Microsoft\Windows\Power Efficiency Diagnostics\AnalyzeSystem" /DISABLE

Sada možete izaći iz naredbenog retka nakon što se naredba izvrši. Ali možete upitati status zadatka da potvrdite da su promjene primijenjene tako što ćete pokrenuti sljedeću naredbu:

schtasks /Query /TN "\Microsoft\Windows\Power Efficiency Diagnostics\AnalyzeSystem"

Izlaz bi trebao izgledati kako slijedi:

Folder: \Microsoft\Windows\Power Efficiency Diagnostics
TaskName Next Run Time Status
===================== =========== ===============
AnalyzeSystem N/A Disabled

That’s it!

Nakon dovršetka zaobilaznoga rješenja ili samog rješenja, trebalo bi riješiti problem visoke potrošnje CPU-a i memorije^{(high CPU & memory usage)} u sustavu Windows 10 uzrokovan postavkom ljetnog računanja vremena (DST) .^{(Daylight Saving Time (DST) setting )}

DST setting causes high CPU & memory usage on Windows 10

Daylight Saving Time (DST), also daylight savings time or daylight time and summertime is the practice of advancing clocks during warmer months so that darkness falls later each day according to the clock. If you notice high CPU and memory usage in Windows 10 when DST is configured, then this post is intended to help you. In this post, we will identify the possible cause and then offer the corresponding workaround as well as the solution you can try to remediate the issue.

Let’s take a look at a typical scenario where you can encounter this issue of DST setting causes high CPU & memory usage on Windows 10.

You have a computer that’s running Windows 10 to use a time zone where daylight saving time (DST) changes occur at midnight (12:00 AM) instead of at 2:00 AM. In this situation, you may experience the following issues.

Issue 1
The TaskHostw.exe process consumes 100 percent of CPU resources. Therefore, system performance and battery life decrease dramatically. On small form factor devices, this issue may affect thermal management, as the process keeps running in a loop doing time conversion calculations.

Issue 2
The pagefile consumes excessive disk resources, which triggers high disk utilization.

Issue 3
Excessive memory use occurs.

Issue 4
Excessive disk, CPU, or memory use causes the computer to hang or freeze.

Daylight Saving Time setting causes high CPU & memory usage

This issue of Daylight Saving Time (DST) setting causes high CPU & memory usage on Windows 10 occurs because of a race condition in the TaskHostW.exe process (a generic host process for Windows services) that runs one of the energy.dll scheduled tasks. This scheduled task runs according to the time that’s set on the computer. This issue occurs only on the day when DST changes.

The energy.dll file is loaded when DST changes occur at midnight instead of at 2:00 AM.

If you’re faced with this issue, you can try our recommended solution or workaround (per your requirement) described below to mitigate the issue.

To resolve this issue, upgrade your computer to the latest version of Windows 10.

If for one reason or the other, like you prefer to stay on your current Windows 10 install and not upgrade or upgrading to the latest version of Windows 10 or you’re already running the most current version of Windows 10 but the issue is not resolved you can try the workaround offered below.

To work around the issue, you need to disable the Power Efficiency Diagnostics task by using one of the following methods.

1. Use the Task Scheduler UI (User Interface)
2. Use the Command Prompt

Let’s take a look at the description of the steps as it concerns each of the methods to resolve the DST setting causes high CPU & memory usage on Windows 10.

1] Use the Task Scheduler UI (User Interface)

To use the Task Scheduler to disable the Power Efficiency Diagnostics task, do the following:

• Press Windows key + R to invoke the Run dialog.
• In the Run dialog, type taskschd.msc and hit Enter to open the Task Scheduler console.
• In the Task Scheduler console, navigate to the following:

Task Scheduler Library > Windows > Power Efficiency Diagnostics

• In the middle pane, select and right-click AnalyzeSystem.
• Click Disable.

You can exit the Task Scheduler console.

2] Use the Command Prompt

To use the Command Prompt to disable the Power Efficiency Diagnostics task, do the following:

• Press Windows key + R to invoke the Run dialog.
• In the Run dialog box, type cmd and then press CTRL + SHIFT + ENTER to open Command Prompt in admin/elevated mode.
• In the command prompt window, copy and paste the command below and hit Enter.

schtasks /Change /TN "\Microsoft\Windows\Power Efficiency Diagnostics\AnalyzeSystem" /DISABLE

You can now exit the command prompt once the command executes. But, you can query the status of the task to confirm that the changes applied by running the following command:

schtasks /Query /TN "\Microsoft\Windows\Power Efficiency Diagnostics\AnalyzeSystem"

The output should appear as follows:

Folder: \Microsoft\Windows\Power Efficiency Diagnostics
TaskName Next Run Time Status
===================== =========== ===============
AnalyzeSystem N/A Disabled

That’s it!

After completing the workaround or the solution itself, the issue of high CPU & memory usage on Windows 10 caused by Daylight Saving Time (DST) setting should be resolved.
