New Windows 11 update generates slowness and high resource consumption problems on several PCs
A recent cumulative update for Windows 11, identified by the code KB5072033, is generating a wave of complaints from users around the world. Reports indicate a significant degradation in computer performance after installing the patch, with symptoms including general system slowdowns, crashes and abnormally high consumption of resources such as CPU, RAM and disk.
The issue appears to affect a wide range of hardware configurations, from older machines to high-end equipment. User frustration has been widely shared on online forums and social networks, where many are looking for solutions to reverse the negative impact of the update and restore their devices to their original performance.
Initial investigations by the technical community point to a specific change in an operating system service as the likely cause of the failure. Microsoft has not yet issued an official statement acknowledging the error, but the number of reports suggests a widespread problem that may require a future correction by the company.

Symptoms reported by affected users
The main symptoms reported after installing the KB5072033 update are consistent among different users. The most common is a marked slowdown in everyday tasks, such as starting the operating system, opening applications or simply navigating between windows.
Another critical point is the high consumption of system resources. Muitos observed on Gestor of Tarefas that CPU and disk usage spikes to levels close to 100% for no apparent reason, even when the computer is idle. Este behavior overloads the hardware and makes the system practically unusable in some cases.
Computers equipped with traditional hard drives (HDD) appear to be the most severely impacted. The nature of the problem, which involves intensive disk reads and writes, means that these slower devices become a major bottleneck, resulting in long wait times and frequent freezes.
Although systems with SSDs, especially faster NVMe models, suffer less from the problem, they are not immune. Utilizadores with high-end hardware also reported a notable loss of agility and responsiveness, indicating that the flaw resides in the software and is not limited to more modest configurations.
What is the AppXSVC service and its relationship to the problem
In-depth technical analysis indicates that the culprit for the chaos is “AppX Deployment Service”, or AppXSVC. Este is a legitimate component of Windows, responsible for installing, uninstalling and updating applications from Microsoft Store and other apps in the AppX/MSIX format. Under normal conditions, this service is configured to start “manually”, that is, it is only activated when necessary, such as when installing a new program. However, update KB5072033 appears to have improperly changed the startup type of this service to “Automatic”. Esta change causes AppXSVC to constantly run in the background from Windows startup, continuously scanning and processing application packages, which consumes an excessive amount of system resources and causes the widespread slowdowns that users are experiencing. Constant disk activity is particularly detrimental to overall performance, explaining why the symptoms are so pronounced.
Technical details of the update failure
Changing AppXSVC’s startup mode from “manual” to “automatic” is a subtle change, but with drastic consequences for system performance. Quando a service is set to automatic, it competes for CPU, RAM and disk I/O resources from the moment the system is turned on. Para a service like AppXSVC, which does not need to be always active, this configuration represents a continuous waste of processing capacity, impacting all other tasks that the user tries to perform.

In corporate environments, the problem can be even more serious. Performance degradation can lead to a drop in productivity and generate an increase in the number of calls for IT teams. Administradores systems may be forced to manually intervene on dozens or hundreds of machines to reverse the change, a process that consumes valuable time and resources. The failure highlights how a small change not properly tested can have a ripple effect across the entire Windows ecosystem.

How to check if your system is affected
To check if your computer is affected by this specific problem, the process is relatively simple. Basta access the “Services” application of Windows. Pode do this by pressing the “Win + R” keys, typing “services.msc” in the dialog box and pressing Enter. In the list of services, look for “AppX Deployment Service (AppXSVC)”. If the “Type of Arranque” column says “Automatic”, it is very likely that your system’s slowness is being caused by this fault.
Temporary solution to fix slowdown
While Microsoft does not release an official fix, the user community has discovered an effective workaround. The method is to manually revert the AppXSVC service startup type to its default setting, which is “Manual (Triggered)”.
Para To apply this fix, you must use PowerShell or Terminal from Windows with administrator privileges. To do this, right-click on the Iniciar menu, select “Terminal (Admin)” and, in the window that opens, paste the following command: `sc config AppXSVC start= demand`.
After executing the command, it is essential to restart the computer for the change to take effect. Most users who have applied this procedure have reported an immediate and substantial improvement in performance, with the system returning to its normal speed.
Positioning of Microsoft and next steps
So far, Microsoft has not officially recognized the flaw as a known bug resulting from the KB5072033 update. The company normally uses its official channels, such as the Windows health status page, to report these types of problems, but the case has not yet been listed.

However, the expectation is that, with the increasing number of reports, the Windows engineering team will investigate the problem. The definitive solution should come in the form of a new patch in a future cumulative update, which reverts the AppXSVC service configuration to its correct state.
Other patch improvements and fixes
Despite the performance issue, update KB5072033 is designed to bring important improvements to Windows 11. The patch is part of the Microsoft monthly security update cycle, known as “Patch Tuesday”, and includes fixes for several operating system vulnerabilities.
In addition to security fixes, these cumulative updates often address other minor bugs and improve overall system stability. For this reason, simply uninstalling the patch is not the most recommended solution, as it would leave the system exposed to security flaws that have already been fixed.
