Windows-related issues

Is it OK to delete these entries?

Ciao, non riesco ad attivare il SECURE BOOT. Il sistema risulta soddisfare tutti i requisiti ma quando abilito il Secure Boot, il sistema al riavvio va in Diagnostica e mi dice di non essere riuscito nel ripristino ... quindi devo disabilitare per poter continuare.
Ho il BIOS aggiornato ed in modalita' UEFI, i dischi in Base GPT... ma nulla
Accetto suggerimenti.
Grazie mille.

I run Win 11 Pro on my laptop. Until late September, I've never had an issue with the Win backup process to an external SSD drive, It's been a weekly automated process since I bought my laptop 3+ years ago. Only suddenly, it's not. It appears all the desired content from my C: drive SSD gets backed up, but whatever normally happens next fails, and I ger a message the backup didn't complete. I tried unchecking the checkbox to create a system image file, in case that was a problem. It made no difference. I tested and even reformatted the backup drive to NTFS standards. I've run out of things to try, but I still very much want a successful weekly data backup that's NOT to the cloud. Any suggestions? Thanks for whatever guidance you can offer.

How to resolve / Cannot receive updates

Hello, I have downloaded your program to clean up my computer and it has helped a lot. It stopped crashing for a week or two but now crashes again randomly 2, 3 times a day. 95% of the time it makes a restart while 5% I have to unplug the PC to retart the PC.
Any ideas on whats happening. Don't think its a overheat problem as it sometime happens 10 minutes after I started the PC. Also tried different browser, Chrome, Edge and Brave , no difference.

Могли бы вы порекомендовать ВПН для обхода блокировок сайта и игры ?
