Critical Windows security update will require multiple restarts
For the first time in more than a decade, Microsoft has begun a major renewal process for Secure Boot keys, which will require users to restart their computers more frequently. Current credentials expire in June, which is why the technology giant has been distributing correction packages in a staggered manner since April.
The deadline for renewing system protection credentials
These digital signatures act as an essential shield, preventing malicious code, such as bootkits, from being executed before the operating system even loads. If the machine does not receive new certification within the stipulated deadline, serious verification failures may prevent the equipment from functioning correctly. Although the company initially stated that it would be enough to restart the PC once, recent communications confirm that the procedure may require several shutdown and restart cycles.

Consumers who purchased computer equipment in the last twenty-four months probably already have their systems protected invisibly. On the other hand, the scenario is worrying for older hardware, especially those running Windows 10, which are at risk of becoming vulnerable if continuous packet reception is not activated.
The financial impact of keeping old computers operating safely
Outdated equipment represents the biggest weak link during this structural change. For those who still use Windows 10 on old machines, the developer offers the Extended Security Updates (ESU) program, for a fee to guarantee protection for longer. In practice, this requirement creates a financial dilemma, forcing many individuals and companies to choose between paying additional subscriptions or purchasing computers compatible with Windows 11.

The strategy of releasing files gradually aims to avoid a widespread collapse of servers and daily operations. Even so, the number of times that machines will need to be restarted generates apprehension, especially in complex corporate networks and for professionals who use configurations with several simultaneous screens.
Unexpected crashes in recent packages affect the use of multiple screens
Adding to this transition scenario, the packages identified as KB5083769 and KB5082052, released recently to close critical loopholes, brought unexpected headaches. Several system administrators reported that files linked to Remote Desktop began to display distorted text boxes, transforming important data into visual blocks that were impossible to read.

This visual bug predominantly affects workstations that use two or more monitors operating at different resolutions and zoom scales. Microsoft’s engineering team has already publicly acknowledged the flaw and assured that it is developing a corrective patch, although there is still no exact date for the release of this solution.
The balance between the hassle of restarts and protection against malware
Having to stop work several times to restart the machine is the price to pay to maintain data integrity. The exchange of these cryptographic keys, originally implemented in the days of Windows 8, considerably raises the barrier against intruders, eliminating loopholes that cybercriminals could exploit to inject viruses directly into the motherboard’s firmware.

Consequently, this technical movement acts as a catalyst to accelerate the retirement of old operating systems. Computers that do not meet the minimum requirements for the latest versions will end up isolated, losing access to essential defenses unless their owners invest financially in long-term support.
Main points of attention during this update period:
- Original security signatures expire mid-year.
- Recent packages (KB5083769 and KB5082052) have generated GUI bugs.
- The paid ESU program appears as the only way to keep Windows 10 safe.
- A definitive patch for the corrupted texts is being created by the developer.
Preventative measures to avoid failures during the installation process
The main guideline is to access system settings and confirm that automatic download of improvements is enabled. For those who work with more than one monitor, the golden tip is to temporarily standardize the display scale of all screens before downloading the files. IT managers who manage large volumes of old PCs need to quickly calculate whether it is worth subscribing to extended support or starting to purchase new hardware.
As the June deadline approaches, the company responsible for the operating system continues to collect instability reports sent by the community. The expectation is that the definitive fix for the unreadable texts on the Remote Desktop will be distributed in the coming weeks, stabilizing the virtual environment.
