Cum resetezi stiva de retea in Windows cand nu functioneaza internetul

Uneori, un PC nu mai are internet desi reteaua fizica este in regula: cablul e conectat sau WiFi-ul e asociat, alte dispozitive din aceeasi retea functioneaza, dar pe statia respectiva paginile nu se incarca, apar erori de DNS, sau conexiunea arata “No Internet” cu semnul de exclamare. Deseori acest lucru apare dupa dezinstalarea unui VPN sau antivirus, dupa o infectie curatata, sau dupa o configurare gresita ramasa in sistem.

In loc sa reinstalam Windows sau sa umblam prin zeci de setari, de multe ori este suficient sa resetam stiva de retea la starea implicita: cache-ul DNS, adresa IP, catalogul Winsock si stiva TCP/IP. Windows are comenzi dedicate pentru fiecare.

Cum gasesti si opresti aplicatiile care pornesc cu Windows si incetinesc pornirea

O plangere frecventa a utilizatorilor este ca PC-ul “porneste greu”: de la apasarea butonului pana cand se poate lucra efectiv trec minute intregi, desktopul apare dar ramane blocat, iar hard diskul sau reteaua sunt la 100% imediat dupa logare. Cauza cea mai comuna nu este un virus, ci multimea de aplicatii care s-au adaugat singure la pornirea Windows-ului: clienti de cloud, launchere de jocuri, agenti de update, aplicatii de chat, utilitare ale imprimantelor.

Windows are tot ce trebuie ca sa vedem si sa oprim aceste aplicatii, fara programe externe. In plus, este important sa stim ca “startup” inseamna mai multe locuri, nu doar lista din Task Manager.

Fix Game stuttering and Micro-Lags Caused by NPU/AI Features and “Recall / Copilot”

Problem: On newer laptops or PCs (especially those equipped with NPUs or Copilot+ features), games or graphics-intensive applications experience brief frame hitches (micro-stuttering), even though GPU and CPU usage are nowhere near 100%

Cause: Background local indexing and contextual analysis services (AI Core Services / WebExperienceHost) continuously attempt to process screen frames or text in real time.

How to fix Windows update error 0x800f0922 on Windows 11 via EFI System Partition cleanup

A Windows 11 cumulative update (24H2 or 25H2) downloads normally and asks for a restart. During the reboot phase the installation stalls at around 35–36%, displays the “Undoing changes” message, rolls back, and Windows Update history reports:

0x800f0922

The update is offered again on the next check and fails in exactly the same way. Disk Cleanup, sfc /scannow and the Windows Update Troubleshooter change nothing, because the partition causing the failure is not the one they clean.

Supporting symptoms that confirm the pattern:

  • the failure happens only during the reboot phase, never during download;
  • free space on C: is plentiful (tens or hundreds of GB);
  • the same update installed without issues on other machines from the same batch.

When this article applies. Error 0x800f0922 has several distinct causes, covered separately on this site: system repair commands (DISM/SFC), Registry settings, firewall rules, Windows Features (.NET 3.5) and UEFI Secure Boot. This article covers the remaining cause, and the most common one in 2026: insufficient free space in the EFI System Partition. If you have already worked through the articles above without success, and the failure occurs consistently at around 35% during reboot, this is the right place.
